Biotin Quantitation/Biotinylation
ReadiLinkTM Protein Biotinylation Kit * Powered by ReadiViewTM Biotin Visionization Technology*
Cat # Size Storage Condition5521 1 kit < - 15 oC
Biotin is widely used for labeling biomolecules, in particular, antibodies. This kit is primarily optimized for the preparation of biotin-labeled antibodies for enzyme immunoassay. However, it can also be used to label any proteins and biomolecules that contain primary amines. The kit uses our ReadiView™ Biotin (3059) that reacts with an amino group of antibodies and other biomolecules. Our unique biotin contained in the kit carries a color tag to indicate the degree of biotinylation, thus eliminating the troublesome HABA biotinylation determination step. The HABA biotinylation assay is notoriously inaccurate although many efforts have been taken to improve the HABA assay accuracy (including our kit 5522). The color tag is carefully selected to avoid the interference of either biotin binding or fluorescence detection.
This kit contains all the necessary reagents for labeling and purifica-tion. On our hands, 5 to 8 biotin molecules can be conjugated to each IgG molecule using this kit. The kit is designed for 3 conjuga-tion reactions. For each conjugation reaction the amount of mate-rial can label up to 10 mg protein. The entire process only takes less than an hour. The degree of biotinylation can be readily calculated by the following equation with a simple absorption spectrum.
Number of Biotin/Conjugate = [A351/29300] ÷ [A280/ξprotein]

AmpliteTM Colorimetric Biotin Quantitation Kit
Cat # Size Storage Condition5522 1 kit < - 15 oC
The avidin/streptavidin-biotin interaction is the strongest known non-covalent biological interaction (Kd = 10-15 M-1) between a pro-tein and its ligand. The bond formation between biotin and avidin/streptavidin is very rapid and unaffected by pH, organic solvents, and other denaturing agents. Both avidin and streptavidin have essentially irreversible biotin-binding properties since bound biotin can only be released by denaturing the subunits of the proteins. The tight and specific binding of biotin and its derivatives to various avidins has been extensively explored for a number of biological applications.
Amplite™ Colorimetric Biotin Quantitation Kit is used for determin-ing the molar ratio of biotin incorporated into a protein using the HABA-Avidin method. The HABA dye (4´-hydroxyazobenzene-2-car-boxylic acid) binds to avidin to produce a yellow-orange colored complex which absorbs at 500 nm. Free biotin will displace the HABA dye and cause the absorbance to decrease. A standard curve can be established using the free biotin to estimate the number of moles of biotin incorporated after biotinylating a protein. The kit provides a convenient method for estimating the molar ratio of biotin to protein in biotin-protein conjugates or for quantitating biotin concentration in a solution. It is best used to determine biotin concentration in the range from 1 to 20 µM.

ReadiLinkTM KLH Conjugation Kit *For Antibody Development*
Cat # Size Storage Condition5502 1 kit 2-6 oC
Keyhole Limpet Hemocyanin (KLH) is one of the most commonly used carrier proteins in the conjugation of peptides for antibody production. Mariculture keyhole limpet hemocyanin (mcKLH) is a hemocyanin from the Concholepas concholepas mollusk with immunogenic properties similar to those of KLH. However, mcKLH is a more stable and efficient carrier protein for the production of antibodies to haptens and peptides. It contains numerous sites per molecule for effective conjugation of peptides and other antigens using amine-reactive or carboxy-reactive crosslinkers. mcKLH is currently the industry standard for antibody production against a hapten or peptide. This ReadiLink™ KLH Conjugation Kit is primarily optimized for the simple preparation of hapten-carrier conjugates for immunization and antibody production.
Our ReadiLink™ KLH Conjugation Kit provides a one-step conjuga-tion method of a hapten to a carrier protein using the carboxy-reac-tive carbodiimide as the crosslinker. The resulting conjugate is used for eliciting an immune response and antibody production against the hapten. The carboxy-reactive carbodiimide reacts with exposed carboxy and amino groups on peptides and proteins to form stable bonds. The kit contains mcKLH formulated in buffers compatible with the carboxy-reactive carbodiimide reactions and desalting spin columns, which offer exceptional protein recovery with a simple centrifugation step.
ReadiLinkTM BSA Conjugation Kit *For Antibody Development*
Cat # Size Storage Condition5501 1 kit < - 15 oC
Bovine serum albumin (BSA) is the most abundant protein used for numerous biochemical applications including ELISAs (Enzyme-Linked Immunosorbent Assays), immunoblots, and immunohisto-chemistry. Like most abundant plasma proteins, BSA is very stable and soluble. In addition, the 67 kDa protein is sufficiently large and complex to be fully immunogenic. It contains numerous sites per molecule for effective conjugation of peptides and other antigens using amine-reactive or carboxy-reactive crosslinkers. Consequent-ly, BSA is a popular carrier protein for conjugation to haptens and other weak antigens to make them more immunogenic for antibody production. This ReadiLink™ BSA Conjugation kit is primarily opti-mized for the simple preparation of hapten-carrier conjugates for immunization and antibody production.

AmpliteTM Fluorimetric Maleimide Quantitation Kit*Green Fluorescence*
Cat # Size Storage Condition5523 1 kit < - 15 oC
Sensitive assays of maleimide and thiol groups are required for the efficient conjugation of proteins that are expensive and available only in small amounts. A variety of crosslinking reagents with a ma-leimide group are widely used for crosslinking proteins to proteins or proteins to other biomolecules. There are few reagents or assay kits available for quantifying the number of maleimide groups that are introduced into the first protein. All the commercial kits have tedious protocols.
Our Amplite™ Fluorimetric Maleimide Qutitation kit uses a pro-prietary dye that has enhanced fluorescence upon reacting with a maleimide. The kit provides a sensitive, one-step fluorimetric method to detect as little as 10 picomoles of maleimide in a 100 µL assay volume (100 nM). The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to au-tomation without a separation step. Its signal can be easily read by a fluorescence microplate reader at Ex/Em = 490/520 nm. Compared to kit 5525, this fluorometric assay is more sensitive, and has less interference from biological samples.
Amplite™ Colorimetric Maleimide Quantitation Kit
Cat # Size Storage Condition5525 1 kit < - 15 oC
Maleimides can be directly assayed spectrophotometrically at 302 nm. However, the small extinction coefficient of 620 M-1cm-1 renders this assay insensitive, and the assay is further complicated by the protein absorbance at the same wavelength.
This colorimetric maleimide assay kit quantifies maleimide groups by first reacting a sample with a known amount of thiol present in excess and then assaying the remaining unreacted thiol using 4,4'-DTDP with a molar extinction coefficient of 19,800 M -1cm-1. The amount of maleimide is calculated as the difference between the initial amount of thiol and the amount of unreacted thiol after the complete reaction of all maleimide groups. This spectrophotometric assay for the determination of maleimide groups is a reverse GSH assay. It takes advantage of the high reactivity of thiols of GSH with the maleimide moiety. Maleimide of the sample is allowed to form a stable thiosuccinimidyl linkage with GSH. After the reaction of the sample is complete, the excess GSH, i.e., the remaining thiols of GSH in the reaction mixture, is estimated by using 4,4'-DTDP. The amount of GSH reacted with the sample is titrated to determine the extent of maleimide.

Amplite™ Fluorimetric Thiol Quantitation Assay Kit*Green Fluorescence*
Cat # Size Storage Condition5524 1 kit < - 15 oC
The detection and measurement of free thiol (such as free cysteine, glutathione, and cysteine residues in proteins) is one of the essential tasks for investigating biological processes and events in many bio-logical systems. There are a few reagents or assay kits available for quantitating thiol content in biological systems. All the commercial kits either lack sensitivity or have tedious protocols.
Our Amplite™ Fluorimetric Thiol Qutitation Assay Kit provides an ultrasensitive fluorimetric assay to quantitate thiol content that exists either in a small molecule or on a protein. The proprietary non-fluorescent dye used in the kit becomes strongly fluorescent upon reacting with thiol. The kit can detect as little as 1 picomole of cysteine or GSH in a 100 µL assay volume (10 nM). The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step. The thiol sensor used in the kit generates a strongly fluorescent ad-duct upon reacting with a thiol compound. The resulted adduct has the spectral proterties almost identical to those of fluorescein. In addition, both absorption and emission spectra of the thiol adduct are pH-independent, making this assay kit highly robust. The signal can be easily read by a fluorescence microplate reader at Ex/Em = 490/520 nm.
Amplite™ Fluorimetric Fluorescamine Protein Quantitation Kit *Blue Fluorescence*
Cat # Size Storage Condition11100 1 kit < - 15 oC
Protein quantification is necessary in protein purification, electro-phoresis, cell biology, molecular biology, and other research ap-plications. Biuret, Lowry, BCA and Bradford assays are routinely used for estimating protein concentration. However, these colorimetric assays are less sensitive, and require large sample volume to ensure higher accuracy. Our fluorescamine-based protein quantification kit is significantly more sensitive than existing standard colorimetric measurements, e.g., Bradford and Bicinchoninic acid (BCA) assays.
Fluorescamine is intrinsically nonfluorescent but reacts rapidly with primary aliphatic amines, including those in peptides and proteins, to yield a blue-green-fluorescent derivative. The Amplite™ Fluor-escamine Protein Quantitation Kit provides a simple method for quantifying protein concentration in solutions. As little as 3 µg/mL of BSA can be detected. The kit can be performed in a convenient 96-well or 384-well microtiter-plate format. It can be completed within 30 minutes with the fluorescence signal easily monitored at Ex/Em = 380/470 nm. This kit has been used for (1). studying protein/protein interactions; (2). measuring column fractions after affinity chromatography; (3). estimating percent recovery of mem-brane proteins from cell extract; and (4). high-throughput screening of fusion protein.

PhosphoWorks™ Fluorimetric ADP Assay Kit *Red Fluorescence*
Cat # Size Storage Condition21655 1 kit < - 15 oC
All signal transduction pathways are regulated on some level by phosphorylation, making phosphorylation relevant to most, if not all, areas of cell signaling and neuroscience research. Kinases are of interest to researchers involved in drug discovery due to their broad relevance to diseases. Most of the commercial protein kinase assay kits are either based on monitoring the phosphopeptide formation or ATP depletion. For the kinase assay kits that are based on the detection of phosphopeptides, one has to spend time and efforts to identify an optimized peptide substrate.
The PhosphoWorks™ Fluorimetric ADP Assay Kit is used for monitor-ing ADP formation, which is directly proportional to enzyme phos-photransferase activity and is measured fluorimetricaly. This kit pro-vides a fast, simple, and homogeneous assay for the measurement of kinase activities. It is a non-radioactive and no wash method to detect the amount of ADP produced as a result of enzyme activity. Its characteristics of high sensitivity (<0.3 μM ADP) and broad ATP tolerance (1-300 μM) make it an ideal kit for determining kinase Michaelis-Menten kinetics as well as for screening and identifying kinase inhibitors. The kit has been used for screening kinase inhibi-tors and profiling kinase activities.

Amplite™ Fluorimetric Acetylcholine Assay Kit *Red Fluorescence*
Cat # Size Storage Condition11403 1 kit < - 15 oC
Acetylcholine (ACh) and its metabolites are involved in three main physiological purposes: structural integrity and signaling roles for cell membranes, cholinergic neurotransmission (acetylcholine syn-thesis), and as a major source for methyl groups via its metabolite. Acetylcholine is a neurotransmitter in both the central and periph-eral nervous systems. It is one of many neurotransmitters in the au-tonomic nervous system (ANS) and the only neurotransmitter used in the motor division of the somatic nervous system. It is involved in a number of biological events that are related to diabetic vasculopa-thy, hypertension, and Alzheimer’s disease.
Our Amplite™ Fluorimetric Acetylholine Assay Kit provides one of the most sensitive methods for quantifying acetylcholine. The kit uses Amplite™ Red to quantify acetylcholine through the choline oxidase-mediated enzyme coupling reactions. The fluorescence in-tensity of Amplite™ Red is proportional to acetylcholine formation. The kit is an optimized “mix and read” assay. It provides an ultrasen-sitive one-step fluorimetric assay to detect as little as 0.01 nano-moles ACh in a 100 µL assay volume (0.1μM). Its signal can be easily read with a fluorescence microplate reader at Ex/Em = ~540/590 nm or an absorbance microplate reader at ~576 nm.

10052 1 kit < - 15 oC
The formation, reactivity and toxicity of aldehydes originating from the peroxidation of lipids of cellular membranes have received great attention in recent years. Rapid and accurate measurement of aldehydes is an important task for biological research, chemical research, food industry and environmental pollution surveillance. There are a few reagents or assay kits available for quantifying the number of aldehydes. Most of the existing aldehyde test methods are based on separations either by the tedious and expensive HPLC-MS or GC-MS.
Both our Amplite™ Colorimetric Aldehyde Qutitation Kit (10051) and Amplite™ Fluorimetric Aldehyde Qutitation kit (10052) are used for quantifying aldehydes at higher pH. Kit 10052 uses a proprietary fluorogenic dye that generates a strongly fluorescent product upon reacting with an aldehyde. Kit 10052 is much more sensitive than Kit 10051. This fluorimetric kit provides a sensitive mix-and-read method to detect as little as 0.1 nanomole of aldehyde in a 100 µL assay volume (1 µM). The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step. Its signal can be easily read by a fluorescence microplate reader at Ex/Em = 365/435 nm.

Very reactive aldehydes, namely 4-hydroxyalkenals, were first shown to be formed in autoxidizing chemical systems. It was subsequently shown that 4-hydroxyalkenals, particularly 4-hydroxynonenal, were formed in substantial amounts under biological conditions, i.e. during the peroxidation of lipids of liver microsomes incubated in the NADPH-Fe system. Many other aldehydes were also identified in peroxidizing liver microsomes or hepatocytes, e.g., alkanals , alk-2-enals, and 4-hydroxyalkenals.
Most of the existing aldehyde test methods are based on separa-tions either by the tedious and expensive HPLC-MS or GC-MS. Our Amplite™ Colorimetric Aldehyde Quantitation kit uses a proprietary dye that generates a chromogenic product upon reacting with an aldehyde. The kit provides a sensitive, one-step colorimetric method to detect as little as 1 nanomole of aldehyde in a 100 µL assay vol-ume (10 µM). The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and readily adapted to automation without a separation step. Its signal can be easily read with an ab-sorbance microplate reader at 405 or 550 nm. This kit has been used for monitoring activities of oxidases that convert an amino group to an aldehyde group.
Figure 4.3. Aldehyde dose response was measured in a 96-well clear plate with Amplite™ Colorimetric Aldehyde Quantitation Assay Kit. As low as 10 µM (1 nanomol/well) of aldehyde can be detected.
Figure 4.4. Formaldehyde dose response was measured in a 96-well black plate with Amplite™ Fluorimetric Aldehyde Quantitation Kit. As low as 1 µM (0.1 nanomol/well) of formaldehyde can be detected with 15 minutes incubation time (n=3).

PhosphoWorks™ Luminometric ATP Assay Kit*Steady Glow*
Cat # Size Storage Condition21609 1 kit < - 15 oC
Firefly luciferase is a monomeric 61 kD enzyme that catalyses a two-step oxidation of luciferin, which yields light at 560 nm. The first step involves the activation of the protein by ATP to produce a reactive mixed anhydride intermediate. In the second step, the ac-tive intermediate reacts with oxygen to create a transient dioxetane, which quickly breaks down to the oxidized product oxyluciferin and carbon dioxide along with a burst of light. When ATP is the limiting component, the intensity of light is proportional to the concentra-tion of ATP. Thus the measurement of the light intensity can be used to quantify ATP with a luminometer.
As Kit 21610, this assay is also based on the detection of ATP using firefly luciferase to catalyze the release of light with ATP and lucif-erin. Complementary to Kit 21610, this kit provides a more stable luminescence signal that lasts for a few hours, making it convenient to be used with the luminometers that are not equipped with liquid handling capacity. Although Kit 21609 is less sensitive than Kit 21610, its more stable signal provides advantages for some particular applications, such as rapid diagnostic applications. This kit has been used successfully for rapid food safety inspection with a hand-held luminometer.

Adenosine triphosphate (ATP) plays a fundamental role in cel-lular energenics, metabolic regulation and cellular signaling. The quantitation of ATP can be used for a variety of biological applica-tions. Because ATP is the energy source for almost all living organ-isms and rapidly degrades in the absence of viable organisms, its existence can be used to identify the presence of viable organisms. The measurement of ATP has been used for cell cytoxicity, detection of bacteria on surfaces, quantification of bacteria in water, somatic cells in culture and food quality.
The PhosphoWorks™ Luminometric ATP Assay Kit comes with all the essential components and provides a fast, simple and homoge-neous luminescence assay for the determination of cell proliferation and cytotoxicity in mammalian cells. This assay is based on the de-tection of ATP using firefly luciferase to catalyze the release of light by ATP and luciferin. It can be performed in a convenient 96-well or 384-well microtiter-plate format and run with many luminescence instruments. The assay is extremely sensitive and can detect 10-100 cells/well. Its high sensitivity permits the detection of ATP in many biological systems, environmental samples and foods. This assay kit has higher sensitivity while Kit 21609 has more stable signal.
Figure 4.5. CHO-K1 cell number was measured with the PhosphoWorks™ Luminescence ATP Assay Kit on a 96-well white plate using a NOVOstar plate reader (BMG Labtech). The kit can detect as low as 10 cells per well. The integration time was 1 sec.

Cholesterol is required to build and maintain cell membranes. It modulates membrane fluidity over the range of physiological temperatures. Within cells, cholesterol is the precursor molecule in several biochemical pathways. Cholesterol is also an important precursor molecule for the synthesis of Vitamin D and the steroid hormones, including the adrenal gland hormones cortisol and aldosterone as well as the sex hormones progesterone, estrogens, together with testosterone and their derivatives.
This Amplite™ Cholesterol Quantitation Assay Kit provides one of the most sensitive methods for quantifying cholesterol. The kit uses Amplite™ Red to quantify the concentration of cholesterol, which is related to the production of hydrogen peroxide in the cholesterol oxidase-mediated enzyme coupling reactions in the presence of cholesterol. The amount of cholesterol is proportional to the con-centration of hydrogen peroxide formed in the enzyme coupling reaction cycle. In the presence of peroxidase, the fluorescence intensity of Amplite™ Red is proportional to the concentration of hydrogen peroxide that is converted to the concentration of choles-terol.

Calcium is essential for all living organisms, particularly in cell physiology, where the movement of calcium ion into and out of the cytoplasm functions as a signal for many cellular processes. Calcium also plays an important role in mediating the constriction and relax-ation of blood vessels, nerve impulse transmission, muscle contrac-tion, and hormone secretion. The serum level of calcium is closely regulated (9 to 10.5 mg/dL) in the human body. Both hypocalcemia and hypercalcemia are serious medical disorders.
Amplite™ Calcium Quantitation Kit provides a simple method for detecting calcium in physiology solutions by using our proprietary red fluorescence probe. The fluorescence signal can be easily read with a fluorescence microplate reader at Ex/Em = 540/590 nm. The kit can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step. The assay can be completed within 30 minutes. With the Am-plite™ Calcium Quantitation Kit, we have detected as little as 0.03 mM calcium. The kit has a broad dynamic range (30 µM to 10 mM). If more sensitive calcium detection is required, we recommend that Quest Fluo-8™ or Fluo-3 be used instead. Both Quest Fluo-8™ and Fluo-3 can be used for determining calcium in nM range.

Choline and its metabolites play an important role in the structural integrity and signaling of cell membranes and cholinergic neuro-transmission (acetylcholine synthesis). It is a major source for methyl groups via its metabolite, trimethylglycine that participates in the S-adenosylmethionine synthesis pathways. Choline deficiency may cause liver disease, atherosclerosis and possibly neurological disorders. Despite its importance in the central nervous system as a precursor for acetylcholine and membrane phosphatidylcholine, the role of choline in mental illness has been little studied.
This Amplite™ Choline Quantitation Kit provides one of the most sensitive methods for quantifying choline. The kit uses Amplite™ Red to quantify the concentration of choline, which is related to the production of hydrogen peroxide in the choline oxidase-mediated enzyme coupling reactions. The amount of choline is proportional to the concentration of hydrogen peroxide formed in the enzyme coupling reaction cycle. In the presence of peroxidase, the fluores-cence intensity of Amplite™ Red is proportional to the formation of hydrogen peroxide that is converted to the concentration of cho-line. The assay can be readily read with a fluorescence microplate reader at Ex/Em = ~540/590 nm. Alternatively the assay can also be read at ~570 nm with an absorption microplate reader.

Ethanol is a powerful psychoactive drug and one of the oldest recreational drugs. It is best known as the type of alcohol found in alcoholic beverages and thermometers. In common usage, it is often referred to simply as alcohol or spirits. Ethanol is a central ner-vous system depressant and has significant psychoactive effects in sublethal doses. A blood ethanol level of 0.5% or more is commonly fatal. Ethanol levels of even less than 0.1% can cause intoxication, with unconsciousness often occurring at 0.3–0.4%. The amount of ethanol in the body is typically quantified by blood alcohol content.
The ability to rapidly perform quantitative measurements of ethanol is highly desirable in life science research, clinical evaluations, food, and pharmaceutical industries. Our non-radioactive ethanol assay is based on the oxidation of ethanol by alcohol oxidase. The kit uses our Amplite™ Red reagent that makes the kit recordable in a dual mode, the fluorescent signal can be easily read by a fluorescence microplate reader at Ex/Em = ~540/590 nm, or its absorption can be readily read by an absorbance microplate reader at ~570 nm. The Amplite™ Fluorimetric Ethanol Quantitation Kit can be performed in a convenient 96-well or 384-well microtiter-plate format. The assay can be completed within 30 minutes and as little as 0.0003% ethanol can be detected.

Glucose, a monosaccharide, is the most important carbohydrate in biology. It is a source of energy and metabolic intermediate for cell growth. As one of the main products of photosynthesis, glucose starts cellular respiration in both prokaryotes and eukaryotes. Glucose level is a key diagnostic parameter for many metabolic disorders, e.g., diabetes.
This Amplite™ glucose assay kit provides a quick and sensitive method for the measurement of glucose. It uses glucose oxidase-based enzyme coupled reactions to detect glucose through the pro-duction of hydrogen peroxide, which is monitored by our Amplite™ Red peroxidase substrate. Amplite™ Red peroxidase substrate can be recorded in a dual mode, the fluorescent signal can be easily read by a fluorescence microplate reader at Ex/Em = 540/590 nm, or its absorption can be read by an absorbance microplate reader at ~570 nm. The assay is robust, and can be readily adapted for a wide variety of applications that require the measurement of glucose. The assay has very low background since it is run in the red visible range that significantly reduces the interference from biological samples. It has demonstrated high sensitivity and low interference with excitation at 570 nm and emission at 590 nm. With the Amplite™ Glucose Quantitation Kit, we can detect as little as 3 μM D-glucose.

Glutamate is a key molecule in cellular metabolism. It is the most abundant excitatory neurotransmitter in the vertebrate nervous system. Nerve impulses trigger release of glutamate from the pre-synaptic cells. In the opposing post-synaptic cell, glutamate recep-tors, such as the NMDA receptor, bind glutamate and are activated. Glutamate works not only as a point-to-point transmitter but also as a spill-over synaptic crosstalk between synapses.
This Amplite™ Fluorimetric Glutamic Acid Assay Kit provides one of the most sensitive methods for quantifying glutamic acid. The kit uses Amplite™ Red to quantify the concentration of glutamic acid, which is related to the production of hydrogen peroxide in the glu-tamate oxidase-mediated enzyme coupling reactions in the pres-ence of glutamic acid. The amount of glutamic acid is proportional to the concentration of hydrogen peroxide formed in the enzyme coupling reaction cycle. In the presence of peroxidase, the fluores-cence intensity of Amplite™ Red is proportional to the formation of hydrogen peroxide that can be converted to the concentration of glutamic acid. The assay can be readily read with a fluorescence microplate reader at Ex/Em = ~540/590 nm. Alternatively the assay can also be read at ~570 nm with an absorption microplate reader, but the sensitivity is reduced by ~10 times.

The monitoring of reduced and oxidized glutathione (GSH) in bio-logical samples is essential for evaluating the redox and detoxifica-tion status of cells and tissues in relation to the protective role of glutathione against oxidative and free-radical-mediated cell injury. Cysteine metabolism disorders include cystinosis, an autosomal recessive disease produced by a defect in lysosomal transport, and cystinuria, a common heritable disorder of amino acid transport. Cysteine is unique among the amino acids found in proteins.
There are a few reagents or assay kits available for quantitating thiols in biological systems. However, all the commercial kits either lack sensitivity or have tedious protocols. Our Amplite™ Fluorimetric GSH Qutitation Kit provides an ultrasensitive fluorimetric assay to quantitate GSH in sample. The kit uses a proprietary non-fluorescent dye that becomes strongly fluorescent upon reacting with thiol. The kit provides a sensitive, one-step fluorimetric method to detect as little as 1 picomole of cysteine or GSH in a 100 µL assay volume. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step.

The Amplite™ Fluorimetric NADP/NADPH Assay Kit provides a sensi-tive, one-step assay to detect as little as 1 picomoles of NADP(H) in a 100 µL assay volume (10 nM). The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and read-ily adapted to automation. Its signal can be easily read by either a fluorescence microplate reader at Ex/Em = 540/590 nm or an absorbance microplate reader at ~576 nm. The longer red emission minimizes the interference from the autofluorescence of biological samples.

Amplite™ Fluorimetric NADP/NADPH Ratio Assay Kit *Red Fluorescence*
Cat # Size Storage Condition
15264 1 kit < - 15 oC
The traditional NAD/NADH and NADP/NADPH assays are done by monitoring the changes in NADH or NADPH absorption at 340 nm. These methods suffer low sensitivity and high interference since the assays are done in the UV range that requires expensive quartz microplates. The low sensitivity of the absorption-based NADP/NADPH assays makes the assays difficult to be automated for high throughput screening that often uses small sample size.
This Amplite™ Fluorimetric NADP/NADPH Ratio Assay Kit provides a convenient method for sensitive detection of NADP, NADPH and their ratio. The enzymes in the system specifically recognize NADP/NADPH in an enzyme recycling reaction that significantly increases detection sensitivity. In addition, this assay has very low background since it is run in the red visible range that considerably reduces the sample interference. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format. Its signal can be easily read by either a fluorescence microplate reader at Ex/Em = 530-570/590-600 nm (maximum Ex/Em = 540/590 nm) or an absorbance microplate reader at ~576 nm. This also provides NADP, NADPH extraction buffer, and cell lysis buffer.

21659 1 kit < - 15 oC
Phosphate is involved in many biological processes. For example, phosphatases, ATPases and several other enzymes catalyze bio-chemical reactions in which inorganic phosphate (Pi) is released from a phosphoester substrate. The detection of many phospho-ester–metabolizing enzymes is difficult because suitable substrates are not available. It is usually necessary to determine inorganic phosphate release using tedious colorimetric assays or radioiso-tope-based methods.
This PhosphoWorks™ Colorimetric MESG Phosphate Assay Kit has been developed for measuring the activity of any Pi-generating enzyme using MESG reagent. The measurement of Pi is based on absorbance change of MESG by phosphate. In the presence of inorganic phosphate, MESG is converted to 2-amino-6-mercapto-7-methlpurine by purine nucleoside phosphorylase with absorption wavelength shift to red. This feature has been used to develop our convenient MESG phosphate assay kit, an alternative to hazard-ous radioactive methods. The MESG substrate gives an absorbance increase at 360 nm on phosphorylysis at pH 6.5-8.5. The assay is shown to quantitate phosphate at the final concentration as low as 0.2 µM. The kit has been used for monitoring ATPase activities. It can also be used for monitoring phosphatase activities.

Cells utilize a wide variety of phosphate and polyphosphate esters as enzyme substrates, second messengers, membrane structural components and vital energy reservoirs. Phosphate is involved in many biological processes. For example, phosphatases, ATPases and several other enzymes catalyze biochemical reactions in which inorganic phosphate (Pi) is released from a phosphoester substrate. The detection of many phosphoester–metabolizing enzymes is difficult because suitable substrates are not available. The tedious radioisotope-based method is usually used to determine inorganic phosphate release.
This PhosphoWorks™ Colorimetric Phosphate Assay Kit has been developed to measure the activity of any Pi-generating enzyme using a modified Malachite Green formulation. It provides sensitive detection of Pi, an alternative to hazardous radioactive methods. The measurement of Pi is based on absorbance change of MG Plus™ in the presence of molybdate. Unlike other Malachite Green formu-lations, this kit gives a completely stable end-point signal that is not prone to precipitation. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format. This assay is non-contin-uous while kit 21660 is a continuous assay. It is also complementary to kit 21659 that uses MESG as a continuous Pi indicator.

Pyrophosphate (PPi) are produced by a number of biochemical reactions, such as ATP hydrolysis, DNA and RNA polymerizations, cyclic AMP formation by the enzyme adenylate cyclase and the enzymatic activation of fatty acids to form their coenzyme A esters.
Our PhosphoWroks™ Pyrophosphate Assay Kit provides the most robust spectrophotometric method for the measurement of pyrophosphate. It uses our proprietary fluorogenic pyrophosphate sensor that has its fluorescence intensity proportionally dependent upon the concentration of pyrophosphate. Our assay is much easier and more robust than enzyme-coupling pyrophosphate methods, which require at least two enzymes for their pyrophosphate detec-tions. Due to its direct measurement of pyrophosphate, this kit is ideal for screening inhibition or activities of enzymes that consume or generate pyrophosphate. The assay can be performed in a conve-nient 96-well or 384-well microtiter-plate format. It is an optimized mix-and-read assay. The kit provides all the essential components for assaying pyrophosphate as listed below:
• Assay buffer• PPi sensor• PPi standard
Figure 4.28. Pyrophosphate and phosphate dose response was measured with the PhosphoWorksTM Fluorimetric Pyrophosphate Assay Kit in a 96-well black solid plate. As low as 1 µM (100 picmoles/well) pyrophosphate can be detected with 10 minutes incubation time.

Acetylcholinesterase (AChE) is one of the most crucial enzymes for nerve response and function. AChE degrades the neurotransmitter acetylcholine (ACh) into choline and acetic acid. It is mainly found at neuromuscular junctions and cholinergic synapses in the central nervous system, where its activity serves to terminate the synaptic transmission. AChE inhibitors are among the key drugs approved for Alzheimer’s disease (AD) and myasthenia gravis.
Our Amplite™ Colorimetric Acetylcholinesterase Assay Kit provides a convenient method for the detection of AChE activity. It uses DTNB to quantify the thiocholine produced from the hydrolysis of acetyl-thiocholine by AChE in blood, in cell extracts, and in other solutions. The absorption intensity of DTNB adduct is used to measure the amount of thiocholine formed, which is proportional to the AChE activity. The kit provides a colorimetric one-step assay to detect as little as 0.1 mU AChE in a 100 µL assay volume (1 mU/mL). Its signal can be easily read by an absorbance microplate reader at ~410 nm. The kit is robust and can be used for continuously monitoring AChE activities. It comes with the following components:
• Acetylthiocholine • Acetylcholinesterase standard• DTNB• Assay buffer

The weakly fluorescent SunRed™ phos-phate is sensitive to phosphatase-induced hydrolysis, giving the SunRed™ fluorophore that possesses intense red fluorescence. Upon phosphatase-induced hydrolysis, the SunRed™ phosphate solution has its absorption blue-shifted more than 100 nm. The maximum absorption of SunRed™ fluorophore at 633 nm makes this substrate an ideal NIR probe that can be readily detected with many fluores-cence instrument systems often equipped with Cy5 settings.
Based on the near infrared fluorescence of SunRed™ fluorophore, the signal can be easily read by a fluorescence microplate reader at Ex/Em = ~630/660 nm. The kit has been used for the high through-put screening of protein phosphatase inhibitors due to its low inter-ference from biological sample.

Caspases play important roles in apoptosis and cell signaling. The activation of Caspase 3/7 (CPP32/apopain) is important for the initi-ation of apoptosis. Caspase 3/7 is also identified as a drug-screening target. Caspase inhibitors have anti-cancer and other pharmalogical potentials. It has been proven that Caspase 3/7 has substrate selec-tivity for the peptide sequence Asp-Glu-Val-Asp (DEVD).
Our Amplite™ Fluorimetric Caspase 3/7 Assay Kit uses Ac-DEVD-AMC as a fluorogenic indicator for Caspase 3/7 activity. AMC peptides are almost non-fluorescent. Cleavage of AMC peptides by Caspase 3/7 generates strongly fluorescent AMC that is fluorimetri-cally monitored at 440-460 nm with excitation of 340-350 nm. It can be used to continuously measure the activities of Caspase 3/7 in cell extracts and purified enzyme preparations with a fluorescence microplate reader or fluorometer. The kit comes with the following components:
• AMC caspase substrate• Ac-DEVD-CHO caspase inhibitor• DTT• Assay buffer

Our Amplite™ Fluorimetric Caspase 3/7 Assay Kit uses (Z-DEVD)2 R110 as fluorogenic indicator for assaying caspase 3/7 activity. R110-derived caspase substrates are probably the most sensitive indicators used for the fluorimetric detection of various caspase activities. R110 peptides are colorless and non-fluorescent. Cleav-age of R110 peptides by caspases generates strongly fluorescent R110 that can be monitored fluorimetrically at 510-530 nm with excitation at 488 nm, the most common excitation light source. The increase in fluorescence of caspase-induced R110 hydrolysis is proportional to the activities of caspases.
This kit can be used to continuously measure the activities of caspase 3/7 in cell extracts and purified enzyme preparations with a fluorescence microplate reader or fluorometer. Many labs have used this kit for screening aspase 3/7 inhibitors. The kit comes with the following components:

Catalase is a common antioxidant heme-containing redox enzyme found in nearly all living organisms that are exposed to oxygen. The enzyme is concentrated in the peroxisome subcellular organelles. Hydrogen peroxide is an ROS that is a toxic product of normal aero-bic metabolism and pathogenic ROS production involving oxidase and superoxide dismutase reactions. By preventing the excessive buildup of H2O2, catalase allows important cellular processes which produce H2O2 as a by-product to take place safely.
The Amplite™ Fluorimetric Catalase Assay Kit provides a quick and sensitive method for the measurement of catalase activity. It can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step. Catalase reacts with H2O2 to produce water and oxygen (O2). Amplite™ Red also reacts with H2O2 to generate a red fluorescent product. Therefore the reduction in fluorescence intensity is propor-tional to catalase activity. The Amplite™ Red substrate used in the assay enables a dual recordable mode. The fluorescent signal can be easily read by either a fluorescence microplate reader at Ex/Em = 540/590 nm or an absorbance microplate reader at ~576 nm. With the Amplite™ Fluorimetric Catalase Assay Kit, we have detected as little as 30 mU/mL catalase in a 100 µL reaction volume.

Glutamate oxidase belongs to the family of oxidoreductases, specifi-cally those acting on the CH-NH2 group of donors with oxygen as an acceptor. It is an enzyme that specifically catalyzes the oxidative de-amination of L-glutamate in the presence of water and oxygen with the formation of o-ketoglutarate, ammonia, and hydrogen peroxide.
The Amplite™ Fluorimetric Glutamate Oxidase Assay Kit provides a quick and ultrasensitive method for the measurement of glutamate oxidase in solution and in cell lysates. In the assay, L-glutamic acid is oxidized to α-ketoglutarate, NH3 and H2O2 by glutamate oxidase. L-Alanine and L-glutamate-pyruvate transaminase are included in the reaction, resulting in multiple cycles of the initial reaction, thus significantly amplifying the production of H2O2. The kit uses our Amplite™ Red substrate which enables a dual recordable mode. The fluorescent signal can be easily read by either a fluorescence micro-plate reader at Ex/Em = 540/590 nm or an absorbance microplate reader at ~576 nm. With the Amplite™ Glutamate Oxidase Assay kit, we have detected as little as 40 μU/mL glutamate oxidase in a 100 µL reaction volume.

13601 1 kit < - 15 oC
Histone deacetylases (HDAC) are a class of enzymes that remove acetyl groups from a ε-N-acetyl lysine amino acid on a histone. Deacetylation restores the positive electric charge of the lysine amino acids, which increases the histone’s affinity to the negatively charged phosphate backbone of DNA. This process generally down-regulates DNA transcription by blocking the access of transcription factors. HDAC inhibitors are being studied as a treatment for cancer.
Our Amplite™ Fluorimetric HDAC Activity Assay Kit provides a quick, convenient, and sensitive method for the detection of HDAC activity. This kit uses our non-peptide HDAC Green™ substrate that is much more sensitive than the peptide-based HDAC substrates such as Ac-RGK(Ac)-R110, Ac-RGK(Ac)-AMC and Ac-RGK(Ac)-AFC. In addition, HDAC Green™ substrate is also much more resistant to protease hydrolysis than other commercial peptide-based HDAC substrates. Our kit can be used for measuring HDAC activity in cell lysates or HDAC inhibitor screening with cell extracts or purified enzymes. The long wavelength emission of the HDAC Green™ substrate makes the assay less interfered from compounds and cell components. HDAC activity is monitored with excitation at 490 nm and emission at 525 nm.

31001 1 kit < - 15 oC
Protein kinases are the enzymes that transfer a phosphate group from a phosphate donor to an acceptor amino acid in a substrate protein. Kinases are of great interest to researchers involved in drug discovery. Most of the commercial protein kinase assay kits are based on monitoring either the phosphopeptide formation or the ATP depletion. For the kinase assay kits that are based on the detection of phosphopeptides, one has to spend time and efforts to identify an optimized peptide substrate while the ATP depletion method suffers various interferences due to the use of luciferase that are inhibited or activated by various biological compounds.
The Amplite™ Universal Fluorimetric Kinase Assay Kit is based on monitoring ADP formation, which is directly proportional to en-zyme phosphotransferase activity and is measured fluorimetrically. This enzyme-coupled kit provides a fast, simple, and homogeneous assay to measure kinase activities. It is a non-radioactive and no wash method to detect the amount of ADP produced from enzyme reaction. Its characteristics of high sensitivity (<0.3 μM ADP) and broad ATP tolerance (1-300 μM) make it an ideal kit for determining kinase Michaelis-Menten kinetics and for screening and identifying kinase inhibitors. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format.

Lysyl oxidase is an extracellular enzyme that catalyzes formation of aldehydes from lysine residues in collagen and elastin precur-sors. These aldehydes are highly reactive, and undergo spontane-ous chemical reactions with other lysyl oxidase-derived aldehyde residues or with unmodified lysine residues. The chemical reactions result in cross-linking collagen and elastin, which is essential for stabilization of collagen fibrils and for the integrity and elasticity of mature elastin. The activity of Lysyl oxidase in biological samples is traditionally assessed by tritium release end-point assays using radio isotope labeled collagen or elastin substrates.
The Amplite™ Fluorimetric Lysyl Oxidase Assay Kit offers a sensi-tive fluorescent assay for detecting the activity of lysyl oxidase. It utilizes a proprietary LOX substrate that releases hydrogen peroxide detected using our Amplite™ ADHP substrate in HRP-coupled reac-tions. This method allows the detection of sub ng/mL lysyl oxidase and is much more sensitive than the currently available assays. It eliminates the interference that occurs in some biological samples and can be readily used to detect lysyl oxidase activity in cell ex-tracts or solutions. Its signal can be easily read by either a fluores-cence microplate reader at Ex/Em = 540/590 nm or an absorbance microplate reader at ~576 nm.
Figure 5.16. Lysyl oxidase dose response was measured on a 96-well black solid plate with the Amplite™ Fluorimetric Lysyl Oxidase Assay Kit. As low as 40 ng of lysyl oxidase can be detected with 30 minutes incubation time (n=3).

Monoamine oxidases (MAO) are a family of flavin-containing amine oxidoreductases that catalyze the oxidation of monoamines. They are found bound to the outer membrane of mitochondria in numer-ous tissues including liver, intestinal mucosa, and nerves. In humans there are two types of MAO: MAO-A and MAO-B. MAO-A is particu-larly important in the metabolism of monoamines ingested in food. MAOs play a major role in the inactivation of neurotransmitters. MAO dysfunction has been associated with depression, schizo-phrenia, substance abuse, attention deficit disorder, migraines, and irregular sexual maturation.
The Amplite™ Monoamine Oxidase Assay Kit provides a quick and sensitive method for the measurement of monoamine oxidase and semicarbazide-sensitive amine oxidase (SSAO) activities in blood samples and other biological samples. The kit uses our Amplite™ Red substrate which enables a dual recordable mode.

MMP-3 (Matrix Metalloproteinase-3), also known as stromelysin-1, is involved in wound repair, atherosclerosis and tumors. Our Amplite™ Fluorimetric MMP-3 Activity Assay Kit uses a Tide Fluor™ 2 (TF2)/Tide Quencher™ 2 (TQ2) fluorescence resonance energy transfer (FRET) peptide as the MMP-3 activity indicator. In the intact FRET peptide, the fluorescence of TF2 is quenched by TQ2. Upon cleavage into two separate fragments by MMP-3, the green fluorescence of TF2 is recovered.
This kit is designed to monitor the activity of an MMP-3 enzyme. The poptide sequence used in the kit is more selective for MMP-3 hydro-lysis than other MMP enzymes. It can also be used to screen MMP-3 inhibitors when a purified MMP-3 enzyme is used. With excellent fluorescence quantum yield and longer wavelength, TF2 shows less interference from autofluorescence of test compounds and cellular components and is much more sensitive than an EDANS/Dabcyl FRET substrate. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format. Its signal can be easily read by a fluorescence microplate reader at Ex/Em = 490/525 nm. The perfect excitation of TF2 at 488 nm makes the assay readily readable with almost all the common fluorescence instruments equipped with Argon laser and FITC filter set.

Its signal can be easily read by a fluorescence microplate reader at Ex/Em = 540/590 nm. The pH-independent fluorescence of TF3 makes the assay reading available for the whole physiological pH range. The high photostability of TF3 might make the TF3/TQ3 FRET peptide a useful imaging probe. Many labs have used this kit for the high throughput screening of MMP inhibitors as potential anticancer drug candidates. This assay might be also used for monitoring cancer cells.

NADPH provides the reducing equivalents for biosynthetic reac-tions and for oxidation-reduction involved in protection against the toxicity of ROS (reactive oxygen species). NADPH is also used for anabolic pathways, such as lipid synthesis, cholesterol synthesis and fatty acid chain elongation. It is a necessary cofactor in many xenobiotic metabolism reactions. In chloroplasts, NADP is reduced to NADPH by ferredoxin-NADP reductase in the last step of the electron chain in photosynthesis reactions. The NADPH produced is used as reducing power for the biosynthetic reactions in the Calvin cycle of photosynthesis. Many oxidoreductases and all ligases use NADPH as coenzyme. NADPH is required for the measurement of oxidase activity catalyzed by P450s, FMOs, NADPH-P450 reductase, and many other oxidase enzymes.
AAT Bioquest’s RediUse™ NADPH Regenerating Kit provides two ready-to-use solutions to regenerate NADPH by a simple mixing. This kit can be used for all NADPH-requiring oxidase assays (cDNA-expressed enzymes and liver fractions). About 300-500 enzyme assays can be performed using this kit. The total number of assays that can be performed depends on one’s experimental design.

Horseradish Peroxidase (HRP) is a small molecule (MW ~40 KD) that is widely used in a variety of biological detections. HRP conjugates are extensively used as secondary detection reagents in ELISAs, im-muno-histochemical techniques as well as Northern, Southern and Western blot analyses. Due to its small size, HRP rarely causes steric hindrance problem with the antibody/antigen complex formation. It is usually conjugated to an antibody in a 4:1 ratio. Additionally, HRP is inexpensive compared to other labeling enzymes.
This kit uses Amplite™ Blue, our chromogenic HRP substrate that is much more sensitive to both H2O2 and peroxidase than other chromogenic peroxidase substrates such as TMB, ABTS, OPD and K-Blue. Amplite™ Blue generates a highly absorptive material that has maximum absorption of 664 nm. This near infrared absorption minimizes the background absorption often caused by the auto-absorption of biological samples. Its signal can be easily read by an absorbance microplate reader at ~664 nm. The kit comes with the following components:
• Amplite™ Blue substrate• HRP and H2O2
• Assay buffer

Enhanced chemiluminescence is a common technique for a variety of detection assays in biology. A horseradish peroxidase enzyme (HRP) is tethered to the molecule of interest (usually through label-ing an immunoglobulin that specifically recognizes the molecule). This enzyme complex catalyzes the conversion of the enhanced chemiluminescent substrate into a sensitized reagent in the vicinity of the molecule of interest. The further oxidation of the substrate by hydrogen peroxide produces an excited molecule which emits light.
This kit uses our Amplite™ luminometric HRP substrate to quantify peroxidase in solutions. It provides an optimized “mix and read” assay protocol.

Proteasome 20S/Protease
Amplite™ Fluorimetric Proteasome 20S Activity Assay Kit *Green Fluorescence*
Cat # Size Storage Condition
13456 1 kit < - 15 oC
The main function of the proteasome is to degrade unneeded or damaged proteins by proteolysis. The most common form of the proteasome in this pathway is the 26S proteasome, an ATP-depen-dent proteolytic complex, which contains one 20S (700-kDa) core particle structure and two 19S (700-kDa) regulatory caps. The 20S core contains three major proteolytic activities including chymo-trypsin-like, trypsin-like and caspase-like activities. It is responsible for the breakdown of the key proteins involved with apoptosis, DNA repair, endocytosis, and cell cycle control.
Our Amplite™ Fluorimetric Proteasome 20S Activity Assay Kit is a homogeneous fluorescent assay that measures the chymotrypsin-like protease activity associated with the proteasome complex in cultured cells. This kit uses LLVY-R110 as a fluorogenic indicator for proteasome activities. Cleavage of LLVY-R110 by proteasome gener-ates strongly green fluorescent R110 that is monitored fluorimetri-cally at 520-530 nm with excitation at 480-500 nm. The kit provides all the essential components with an optimized assay protocol. The assay is robust and can be readily adapted for high-throughput as-says to evaluate the proteasome activities or screen the inhibitors in cultured cells or in solution.

Protease assays are widely used for the investigation of protease inhibitors and detection of protease activities. Monitoring various protease activities has become a routine task for many biological laboratories. Some proteases have been identified as good drug development targets.
Our Amplite™ Universal Fluorimetric Protease Activity Assay Kit is an ideal choice to perform routine assays for the isolation of prote-ases, or for identifying the presence of contaminating proteases in protein samples. The kit uses a fluorescent casein conjugate which is proven to be a generic substrate for a broad spectrum of prote-ases (e.g. trypsin, chymotrypsin, thermolysin, proteinase K, protease XIV, and elastase). In the intact substrate, casein is heavily labeled with a green fluorescent dye, resulting in significant fluorescence quenching. Protease-catalyzed hydrolysis relieves its quenching effect, yielding brightly fluorescent dye-labeled short peptides. The increase in fluorescence intensity is directly proportional to prote-ase activity. The assay can be performed in a convenient 96-well or 384-well microtiter plate format and readily adapted to automation. Its signal can be easily read with a fluorescence microplate reader at Ex/Em = 490/525 nm using FITC filter set.
Figure 5.30. Trypsin protease activity was analyzed by Amplite™ Universal Fluorimetric Protease Activ-ity Assay kit. Protease substrate was incubated with 1 unit trypsin in the kit assay buffer. The control wells had protease substrate only (without trypsin). The fluorescence signal was measured starting from time 0 when trypsin was added. Samples were done in triplicates.

13530 1 kit < - 15 oC
Renin is an enzyme that participates in the body's renin-angiotensin system (RAS) that mediates extracellular volume and arterial vaso-constriction. It regulates blood pressure and electrolyte homoeo-stasis. Angiotensin II constricts blood vessels leading to increased blood pressure. It also increases the secretion of ADH and aldoste-rone, and stimulates the hypothalamus to activate the thirst reflex. An over-active renin-angiotension system leads to vasoconstriction and retention of sodium and water. Renin has been identified to be an attractive target for the treatment of hypertension.
The Amplite™ Renin Assay Kit provides a convenient assay for high throughput screening of renin inhibitors and renin activity using our proprietary iFluor™ 488/TQ™ 520 fluorescence resonance energy transfer (FRET) peptide. In the FRET peptide, the fluorescence of iF-luor™488 is quenched by TQ™ 520. Upon cleavage into two separate fragments by renin, the fluorescence of iFluor™ 488 is recovered, and the fluorescent signal can be easily monitored by a fluorescence microplate reader at Ex/Em = 490/520 nm. This assay is about fifty fold more sensitive than an EDANS/DABCYL-based assay. With the Amplite™ Renin Assay Kit, we have detected as little as 1ng renin in a 100 µL reaction volume.

Cat # Size Storage Condition
13620 1 kit < - 15 oC
Sphingomyelinase (SMase) is an enzyme that is responsible for cleaving sphingomyelin (SM) to phosphocholine and ceramide. Activation of SMases in cells plays an important role in the cellu-lar responses. Five types of sphingomyelinase (SMase) have been identified based on their cation dependence and pH optima of action. They are lysosomal acid SMase, secreted zinc-dependent acid SMase, magnesium-dependent neutral SMase, magnesium-independent neutral SMase, and alkaline SMase. Among the five types, the lysosomal acidic SMase and the magnesium-dependent neutral SMase are considered major candidates for the production of ceramide in the cellular response to stress.
Our Amplite™ Colorimetric Sphingomyelinase Assay Kit provides a sensitive method for detecting neutral SMase activity or screening its inhibitors. The kit uses Amplite™ Blue as a colorimetric probe to indirectly quantify the phosphocholine produced from the hydro-lysis of sphingomyelin (SM) by sphingomyelinase (SMase). It can be used for measuring the SMase activity in blood, cell extracts or other solutions. The absorbance of light at 595 nm is proportional to the formation of phosphocholine, therefore to the SMase activity. The kit is an optimized “mix and read” assay that is compatible with HTS liquid handling instruments.

Amplite™ Colorimetric Superoxide Dismutase (SOD) Assay Kit
Cat # Size Storage Condition
11305 1 kit < - 15 oC
Superoxide dismutases (SOD) are a class of enzymes that catalyze the dismutation of superoxide into oxygen and hydrogen peroxide. Superoxide is one of the main reactive oxygen species in cells. It is a substantial contributor of pathology associated with neurodegen-erative diseases, ischemia reperfusion injury, atherosclerosis and aging. SODs are an important antioxidant defense in nearly all cells exposed to superoxide radicals. In fact, mice lacking SOD1 develop a wide range of pathologies, including hepatocellular carcinoma, an acceleration of age-related muscle mass loss, an earlier incidence of cataracts and a reduced lifespan. Overexpression of SOD protects murine fibrosarcoma cells from apoptosis and promotes cell dif-ferentiation.
The Amplite™ Colorimetric Superoxide Dismutase (SOD) Assay Kit provides a quick and sensitive method for the measurement of SOD activity in solutions. In the assay, xanthine is converted to super-oxide radical ions, uric acid and hydrogen peroxide by xanthine oxidase (XO). Superoxide reacts with SOD Orange™ to generate a product that absorbs around 560 nm. SOD inhibits the reaction of SOD Orange™ with superoxide, thus reduces the absorption at 560 nm. The reduction in the abosoption of SOD Orange™ at 560 nm is proportional to SOD activity. The kit can be performed in a conve-nient 96-well or 384-well microtiter-plate format.

Xanthine oxidase (XO) is an enzyme that catalyzes the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid. It plays an important role in the catabolism of purines. Xanthine oxidase is normally found in liver and jejunum. During severe liver damage, xanthine oxidase is released into blood, so a blood assay for XO is a way to determine if liver damage has happened. Xanthinuria is a rare genetic disorder where the lack of xanthine oxidase leads to high concentration of xanthine in blood and can cause health problems such as renal failure.
The Amplite™ Xanthine Oxidase Assay Kit provides a quick and ultrasensitive method for the measurement of xanthine oxidase activities. It can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step. In the assay, xanthine oxidase catalyzes the oxida-tion of purine bases, hypoxanthine or xanthine to uric acid and superoxide , which spontaneously degrades to hydrogen peroxide (H2O2). The kit uses our Amplite™ Red substrate which enables a dual recordable mode. The fluorescent signal can be easily read by either a fluorescence microplate reader at Ex/Em = 540/590 nm or an absorbance microplate reader at ~576 nm. With the Amplite™ Xanthine Oxidase Assay Kit, we have detected as little as 0.15 mU/mL xanthine oxidase in a 100 µL reaction volume.

Anti-fading
FluoroQuest™ Anti-Fading Kit I *Optimized for Slide Imaging*
Cat # Size Storage Condition
20001 1 kit < - 15 oC
The photon output of a dye represents the average number of cycles of excitation followed by fluorescence emission that the dye goes through before it is irreversibly photobleached. The average photon output is defined by the ratio of fluorescence quantum efficiency to photobleaching quantum efficiency. When exposed to excitation light, fluorescence intensity of dyes decreases due to their photooxidation or other photoreactions. It is ideal to have the maximal ratio of fluorescence quantum efficiency to photobleach-ing quantum efficiency. However, very few fluorescent organic dyes can completely resist photobleaching.
Frequently, when a section has been scanned repeatedly under strong excitation light, dyes could lose significant fluorescence signal before visual evaluation or photography can be accom-plished. For example, the photobleaching of fluoresceins (such as FITC-labeled antibodies) has become a major problem in fluores-cence microscopy. In severe cases (such as phycoprotein-labeled bioconjugates), a fluorescence image with high resolution cannot even be taken due to the extremely high photobleaching rate. The main purpose of FluoroQuest™ Anti-Fading Kits is to reduce the dye photobleaching rate, giving researchers longer observation time. Kit I contains 3 sampler components for different imaging experiments. The components are all premixed and ready-to-use solutions.
FluoroQuest™ Anti-Fading Kit II *Optimized for Plate Imaging*
Cat # Size Storage Condition
20003 1 kit 2 - 6 oC
Light-induced damage to the fluorophores is prominent in the pres-ence of oxygen, most likely via the process mediated by singlet oxy-gen, a reactive oxygen species. In some cases, nonoxygen-mediated radical generation has been indicated as a source of photochemical destruction of fluorescent dyes.
Our FluoroQuest™ Anti-Fading kits have been developed to prevent the fading of fluorescent dyes. To be complementary to Kit I (the slide format), our FluoroQuest™ Anti-Fading Kit II is optimized for the microplate format. Unlike Kit I, Kit II provides only one formula-tion specifically optimized for FITC based experiments.
FluoroQuest™ Anti-Fading Kits are recommended for fixed cells and tissues that have been stained with fluorescent dyes or their biological conjugates (such as dye-antibody conjugates). Cells can be viewed immediately. If long term storage is desired, the reagent can be allowed to harden overnight. However, the staining patterns of FluoroQuest™ Anti-Fading Kits are sharper if viewed immediately. Our fluorescent reagents and assay kits have been extensively benchmarked for live cell analysis applications and are optimal for demanding cell analysis applications involving confocal microscopy, flow cytometry, microplate readers and HCS/HTS, where consis-tency and reproducibility are required.
Figure 6.1. U2OS cells in a 96-well Costar black wall/clear bottom plate were loaded with 1 µM calcein, AM for 1 hour and fixed with 4% formaldehyde for 30 minutes. Anti-fading reagents were added to the samples after removing all the media. The FITC signals were compared at 0 and after 30 seconds exposure using an Olympus fluorescence microscopy. The same exposure settings were used for all the images.

Actin is a globular, roughly 42-kDa protein found in almost all eukaryotic cells. It is also one of the most highly-conserved proteins, differing by no more than 20% in species as diverse as algae and humans. Actin is the monomeric subunit of two types of filaments in cells: microfilaments, one of the three major components of the cytoskeleton, and thin filaments, part of the contractile apparatus in muscle cells. Thus, actin participates in many important cellular processes including muscle contraction, cell motility, cell division and cytokinesis, vesicle and organelle movement, cell signaling, as well as the establishment and maintenance of cell junctions and cell shape.
This particular kit is designed to label F-actins of fixed cells in blue fluorescence. The kit uses a blue fluorescent phalloidin conjugate that is selectively bound to F-actins. The phalloidin conjugate has Ex/Em = 350/450 nm, compatible with DAPI filter set that comes with most of fluorescence microscopes. It is a high-affinity probe for labeling, identifying and quantitating F-actins in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. The kit provides all the essential components with an optimized labeling protocol.

Lysosomes are cellular organelles which contain acid hydrolase enzymes to break up waste materials and cellular debris. Lysosomes digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria. The membrane around a lysosome allows the digestive enzymes to work at pH 4.5. The interior of the lysosomes is acidic (pH 4.5-4.8) compared to the slightly alkaline cytosol (pH 7.2). The lysosome maintains this pH differential by pumping protons (H+ ions) from the cytosol across the membrane via proton pumps and chloride ion channels.
This particular kit is designed to label lysosomes of live cells in green fluorescence of large Stokes Shift at Ex/Em = 405/520 nm.

Mitochondria have been implicated in several human diseases, including mitochondrial disorders and cardiac dysfunc-tion, and may play a role in the aging process. Although most of a cellular DNA is contained in the cell nucleus, the mitochondrion has its own independent genome.
This particular kit is designed to label mitochondria of live cells in green fluorescence at Ex/Em = 490/520 nm.

22823 1 kit < - 15 oC
The activation of caspase 3 (CPP32/apopain) is important for the initiation of apoptosis. It has been proven that caspase 3/7 has sub-strate selectivity for the peptide sequence Asp-Glu-Val-Asp (DEVD). This kit uses TF2-DEVD-FMK as a fluorescent indicator for caspase 3/7 activity. TF2-DEVD-FMK, which is cell permeable and nontoxic, irreversibly binds to activated caspase 3/7 in apoptotic cells. Once bound to caspase 3/7, the fluorescent reagent is retained inside the cell. The binding event prevents the caspase 3/7 from further cataly-sis but will not stop apoptosis from proceeding. Within 15 minutes after being added into the medium, the reagent will start to react with active caspase 3/7 enzymes.
There are a variety of parameters that can be used for monitoring cell apoptosis. This Cell Meter™ Caspase 3/7 Activity Assay Kit is de-signed to detect cell apoptosis by measuring caspase 3/7 activation in live cells. It is used for the quantification of activated caspase 3/7 activities in apoptotic cells, or for screening caspase 3/7 inhibitors. TF2-DEVD-FMK, the green label reagent, allows for direct detection of activated caspase 3/7 in apoptotic cells by flow cytometry. The kit provides all the essential components with an optimized assay protocol.

Cell Meter™ Intracellular GSH Assay Kit *Optimized for Flow Cytometry*
Cat # Size Storage Condition
22810 1 kit < - 15 oC
There are a variety of parameters that can be used for monitoring cell apoptosis. This particular kit is designed to detect cell apoptosis by measuring the decrease in reduced glutathione (GSH). GSH is important for maintaining redox level of cells. It is involved in many cellular processes including the scavenging of free radicals, drug detoxification, cell signaling, and cell proliferation. The decrease in cellular GSH concentration is an early hallmark in the progression of cell death in response to different apoptotic stimuli in many cells.
Our Cell Meter™ Intracellular GSH Assay Kit uses our proprietary non-fluorescent Thiolite™ Green, which becomes strongly fluores-cent upon reacting with thiol (including GSH in cells). In normal cells, Thiolite™ Green is accumulated primarily in cytosol, but it is partially translocated to mitochondria in apoptotic cells while Thiolite™ Green staining intensity is decreased. Cells stained with Thiolite™ Green can be visualized with flow cytometry at Ex/Em = 490/520 nm (FL1 channel). The kit can be used together with other reagents, such as 7-AAD (#17501) for multi-parametric study of cell viability and apoptosis. The kit is optimized for screening apoptosis activators and inhibitors with flow cytometry.

Our Cell Meter™ assay kits are a set of tools for monitoring cellular functions. There are a variety of parameters that can be used. This particular kit is designed to monitor cell apoptosis by measuring caspase 9 activity. Caspase 9 is a member of the CED-3 subfam-ily. Activated Caspase-9 cleaves downstream caspases such as caspase-3, -6 and -7, initiating the caspase cascade. It is essential for apoptosis during normal development of the central nervous system.
Caspase 9 is proven to have selectivity for the peptide sequence Leu-Glu-His-Asp (LEHD). This kit uses (Ac-LEHD)2-R110 as a fluoro-genic indicator for caspase 9 activity. Cleavage of R110 peptides by caspase 9 generates strongly fluorescent rhodamine 110 (R110)which is monitored at the emission between 520 nm and 530 nm with the excitation between 480 nm and 500 nm. The kit provides all the essential components. The assay is robust and can be readily adapted for high throughput screening. It can be used to either quantify the activated caspase 9 activities in apoptotic cells or screen the caspase 9 inhibitors. Quite a few labs have used this kit for high throughput screenings.

Cell Meter™ Nuclear Apoptosis Assay Kit*Green Fluorescence*
Cat # Size Storage Condition
22811 1 kit < - 15 oC
This particular kit is designed to monitor cell apoptosis by mea-suring the apoptotic chromatin condensation. The compacted chromatin of apoptotic cells binds higher amounts of nuclear dye compared to the healthy cells. The fluorometric assay is based on the detection of the DNA contents in cells using our proprietary non-fluorescent dye that becomes strongly fluorescent upon bind-ing to cellular DNA.
In normal cells, Nuclear Green™ DCS1 is not cell permeable. How-ever, in apoptotic cells, Nuclear Green™ DCS1 can easily get into the cells with compromised plasma membranes. Once inside the cell, the dye binds to intracellular DNA producing highly fluorescent complexes which identify the cells as non-viable cells. The staining density with Nuclear Green™ DCS1 can be measured with a flow cytometer at Ex/Em = 490/520 nm (FL1 channel) or a fluorescence microscope (FITC filter set). The kit can be used together with our other apoptosis reagents, such as our Cell Meter™ NIR Mitochondrial Membrane Potential Detection Kit (#22802), for multi-parametric study of cell viability and apoptosis. The kit is optimized for screen-ing apoptosis activators and inhibitors.

Cat # Size Storage Condition
22791 1 kit < - 15 oC
Our Cell Meter™ assay kits are a set of tools for monitoring cellular functions. There are a variety of parameters that can be used for monitoring cell viability. This particular kit is designed to monitor cell apoptosis by measuring the translocation of phosphatidylserine (PS). In apoptosis, PS is transferred to the outer leaflet of the plasma membrane. The appearance of phosphatidylserine on the cell sur-face is a universal indicator of the initial/intermediate stages of cell apoptosis and can be detected before morphological changes can be observed.
Compared to Annexin V, the Apopxin™ PS sensor used in this kit is reengineered to have a much higher affinity to PS with Kd < 10 nM. The PS sensor has green fluorescence upon binding to membrane PS. The fluorescent sensor has Ex/Em = 490/520 nm, making assay readily run with FITC filter set. Due to its highly enhanced affinity to PS, this kit is more robust than the other commercial Annexin V-based apoptosis kits that are only used with either microscope or flow cytometry platform. This kit can be used with a fluorescence microplate reader besides the microscope and flow cytometry plat-forms. It has been used for HTS applications.

Cell Meter™ Phosphatidylserine Apoptosis Assay Kit *Red Fluorescence*
Cat # Size Storage Condition
22792 1 kit < - 15 oC
Our Cell Meter™ assay kits are a set of tools for monitoring cellular functions. There are a variety of parameters that can be used for monitoring cell viability. This particular kit is designed to monitor cell apoptosis by measuring the translocation of phosphatidylserine (PS). In apoptosis, PS is transferred to the outer leaflet of the plasma membrane. The appearance of phosphatidylserine on the cell sur-face is a universal indicator of the initial/intermediate stages of cell apoptosis and can be detected before morphological changes can be observed.
Compared to Annexin V, the Apopxin™ PS sensor used in this kit is reengineered to have a much higher affinity to PS with Kd < 10 nM. The PS sensor has red fluorescence upon binding to membrane PS. The red fluorescent sensor has Ex/Em = ~590/630 nm with good photostability. The spectral property is compatible with Texas Red® filter set. Due to its highly enhanced affinity to PS, this kit is more ro-bust than the other commercial Annexin V-based apoptosis kits that are only used with either microscope or flow cytometer platform. This kit can be used with a fluorescence microplate reader besides the microscope and flow cytometry platforms. It has been used for HTS applications.

22794 1 kit < - 15 oC
This particular kit is designed to monitor cell apoptosis through measuring the translocation of phosphatidylserine (PS). In apopto-sis, PS is transferred to the outer leaflet of the plasma membrane. The appearance of phosphatidylserine on the cell surface is a universal indicator of the initial/intermediate stages of cell apop-tosis and can be detected before morphological changes can be observed.
This kit uses our proprietary orange fluorescent Apopxin™ PS sensor that specifically binds PS with affinity much higher than Annexin V (Kd < 10 nM). The PS sensor used in this kit has orange fluorescence upon binding to membrane PS. The stain has the spectral proper-ties almost identical to those of Cy3® or Alexa Fluor® 555, making it convenient to be used for the common fluorescence instruments equipped with the light sources and filters for Cy3® or Alexa Fluor® 555 (Cy3® or Alexa Fluor® 555 are the trademarks of GE Healthcare and Invitrogen respectively). Due to its highly enhanced affinity to PS, this kit is more robust than the other commercial Annexin V-based apoptosis kits that are only used with either microscope or flow cytometry platform. This kit can be also used with a fluores-cence microplate reader besides the microscope and flow cytom-etry platforms.

Screen Quest™ Fluo-8 NW Calcium Assay Kits provide homoge-neous fluorescence-based assays for detecting intracellular calcium mobilization. Cells expressing a GPCR of interest that signals through calcium are pre-loaded with Fluo-8 NW which can cross cell membrane. Once inside the cell, the lipophilic blocking groups of Fluo-8 NW are cleaved by esterase, resulting in a negatively charged fluorescent dye that stays inside cells. Its fluorescence is greatly enhanced upon binding to calcium. When cells stimulated with agonists, the receptor signals the release of intracellular calcium, which significantly increase the fluorescence of Fluo-8 NW. The char-acteristics of its long wavelength, high sensitivity, and >100 times fluorescence enhancement make Fluo-8 NW an ideal indicator for the measurement of cellular calcium. The Screen Quest™ Fluo-8 NW Calcium Assay Kits can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation.

Calcium flux assays are preferred methods in drug discovery for screening G protein coupled receptors (GPCR). These kits use a highly calcium-sensitive and membrane-permeable coelenterazine analog as a calcium indicator for the cells that are transfected with apoaequorin gene. Aequorin is a calcium-sensitive bioluminescent protein from the jellyfish Aequorea victoria that has been used extensively as a calcium indicator in cells. The aequorin complex emits blue light when bound to calcium ions. The luminescence intensity is directly proportional to the Ca2+ concentration. Our coelenterazine-based kits are much more sensitive than the fluores-cence-based calcium assay kits (such as Fluo-4, Fluo-3, Calcium-3 and Calcium-4). These kits provide an optimized assay method for monitoring the G-protein-coupled receptors and calcium channels. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation. It might be useful for monitoring the intracellular calcium mobilization in a specified compartment given that recombinant apoaequorin pro-teins can now be targeted to specific organelles, cells and tissues. This kit is more sensitive than the fluorescent calcium assays.

Calcium flux assays are preferred methods in drug discovery for screening G protein coupled receptors (GPCR). Screen Quest™ Ra-tiometric Calcium Assay Kit provides a homogeneous fluorescence-based assay for detecting the intracellular calcium mobilization. Cells expressing a GPCR of interest that signals through calcium are pre-loaded with Fura-2 AM which can cross cell membrane. Once in-side the cell, the lipophilic blocking groups of Fura-2 Am are cleaved by non-specific cell esterases, resulting in a negatively charged fluorescent dye which stays inside the cells. The 340/380 nm excita-tion ratio allows accurate measurements of the intracellular Ca2+
concentration. The characteristics of its ratio measurements reduce the effects of uneven dye loading and cell numbers, dye leakage and photo bleaching. This Screen Quest™ Ratiometric Calcium Assay Kit provides an optimized assay method with no washing step for monitoring the G-protein-coupled receptors and calcium channels.

Adenosine 3’, 5’ cyclic monophosphate (cAMP) is an important second messenger in intracellular signal transduction. Monitoring levels of cAMP is one of the most common ways to screen for ago-nists and antagonists of GPCRs. Screen Quest™ cAMP Colorimetric ELISA Assay Kit is based on the competition between HRP-labeled cAMP and non-labeled cAMP. HRP-cAMP is displaced from the HRP-cAMP/anti-cAMP antibody complex by unlabeled free cAMP. In the absence of cAMP, HRP-cAMP conjugate is bound to anti-cAMP antibody exclusively. However, the unlabeled free cAMP in the test sample competes for anti-cAMP antibody with the HRP-cAMP antibody conjugate, therefore inhibits the binding of HRP-cAMP to anti-cAMP antibody.
Our Screen Quest™ cAMP Colorimetric ELISA Assay Kit provides a sensitive method for detecting adenylate cyclase activity in biochemical or cell-based assay system. Compared to other ELISA cAMP assay kits, our kit eliminates the tedious acetylation step. The kit uses Amplite™ Blue as a colorimetric substrate to quantify the HRP activity. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format.

Screen Quest™ cAMP Fluorescence ELISA Assay Kit provides an optimized assay method for monitoring the activation of adenylyl cyclase in G-protein coupled receptor systems. The assay is based on the competition for a fixed number of antibody binding sites between HRP-labeled cAMP and non-labeled cAMP. HRP-cAMP is displaced from the HRP-cAMP/anti-cAMP antibody complex by unlabeled free cAMP. In the absence of cAMP, HRP-cAMP conjugate is bound to anti-cAMP antibody exclusively. However, the unlabeled free cAMP in the test sample competes for anti-cAMP antibody with the HRP-cAMP antibody conjugate, therefore inhibits the binding of HRP-cAMP to anti-cAMP antibody.
Our Screen Quest™ cAMP Fluorometric Assay Kit provides a sensitive method for detecting adenylate cyclase activity. Compared to other commercial ELISA cAMP assay kits, this cAMP assay kit only requires a single wash step to remove unbound material prior to the devel-opment step. It also eliminates the tedious acetylation step. The kit uses Amplite™ Red as a fluorogenic HRP substrate to quantify the HRP activity. The fluorescent product formed is proportional to the activity of HRP-cAMP conjugate.

Adenosine 3’, 5’ cyclic monophosphate (cAMP) is an important sec-ond messenger in intracellular signal transduction. Screen Quest™ No-Wash cAMP Fluorescence Polarization Assay Kit provides the most convenient assay method for monitoring the activation of adenylyl cyclase in G-protein coupled receptor systems. Compared to other commercial ELISA cAMP assay kits, this homogenous cAMP assay kit does not require a wash step or the acetylation step. The assay is based on the competition for a fixed number of anti-cAMP antibody binding sites between the fluorescent cAMP tracer and non-labeled free cAMP. Free cAMP displaces the fluorescent cAMP tracer from the fluorescent cAMP/anti-cAMP antibody complex. In the absence of cAMP, fluorescent cAMP conjugate is bound to anti-cAMP antibody exclusively. The free cAMP in cAMP test sample competes for anti-cAMP antibody with the fluorescent cAMP tracer, therefore inhibits the binding of the fluorescent cAMP tracer to anti-cAMP antibody. The unbound fluorescent cAMP tracer rotates faster with low MP (polarization value) while anti-cAMP-bound fluores-cent cAMP tracer has much higher MP value. The magnitude of MP change is proportional to the concentration of cAMP in a sample.

As our kit 36376, Screen Quest™ No Wash FRET cAMP Assay Kit provides another convenient assay method for monitoring the ac-tivation of adenylyl cyclase in G-protein coupled receptor systems. Compared to other commercial ELISA cAMP assay kits, this homog-enous cAMP assay kit does not require a wash step or the acetyla-tion step. The assay is based on the competition for a fixed number of anti-cAMP antibody binding sites between the fluorescent cAMP tracer and non-labeled free cAMP. Free cAMP displaces the fluores-cent cAMP tracer from the HRP-cAMP/anti-cAMP antibody complex. The anti-cAMP antibody is labeled with our TR Fluor™ Tb while the cAMP tracer contains our bFluor™ 650. In the absence of cAMP, bFluor™ 650-cAMP conjugate is bound to TR Fluor™ Tb-labeled anti-cAMP antibody exclusively to have a strong FRET. However, the unlabeled free cAMP in the test sample competes for the TR Fluor™ Tb-labeled anti-cAMP antibody conjugate, therefore inhibits the binding of bFluor™ 650-cAMP to anti-cAMP antibody. The bFluor™ 650 labeled cAMP tracer only has fluorescence lifetime of nanosec-ond while TR Fluor™ Tb-labeled anti-cAMP antibody-bound fluo-rescent cAMP tracer has much longer fluorescence lifetime value due to the TR-FRET. The magnitude of FRET is proportional to the concentration of cAMP in a sample. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format.

G protein coupled receptors (GPCR) are one of the largest receptor classes targeted by drug discovery programs. Calcium flux (coupled via Gq pathway) assay is a preferred method in drug discovery for screening GPCR targets. However, over 60% of the known GPCRs signal through adenylyl cyclase activity coupled to cAMP. Most of the existing cAMP assays not only require cell lysis but also lack both temporal and spatial resolution. Screen Quest™ Live Cell cAMP Assay Service Pack provides the real-time monitoring of intracel-lular cAMP change in a high-throughput format without a cell lysis step. The assay works through the cell lines that contain either an exogenous cyclic nucleotide-gated channel(CNGC) or the promiscu-ous G-protein, Gα16. The channel is activated by elevated levels of intracellular cAMP, resulting in ion flux and cell membrane depo-larization which can be detected with either a fluorescent calcium (such as Quest Fluo-8 AM™) or a fluorescent membrane potential dye. Co-expression of Gα16with specific non-Gq-coupled receptors will result in the generation of an intracellular calcium signal upon receptor stimulation. The Screen Quest™ Live Cell cAMP Assay Service Pack provides both cell lines and reagents for the measure-ment of intracellular cAMP changes with a FLIPR, a FDSS or other equivalent fluorescence microplate readers. It has been successfully used to measure Gs and Gi coupled GPCR activity.

The Cell Meter™ assay kits are a set of tools for monitoring cell viability and cellular functions. This particular kit uses two non-fluorescent indicators: CytoCalcein™ Green for viable cells and a cell-impermeable DNA-binding dye for the cells with compromised membranes. The non-fluorescent CytoCalcein™ Green can easily permeate intact live cells and is hydrolyzed by intracellular ester-ase to generate the strongly fluorescent hydrophilic CytoCalcein™ Green which is well-retained in the cell cytoplasm. The esterase activity is proportional to the number of viable cells. The DNA-bind-ing dye is quite polar and impermeable for viable cells that have intact membranes. It becomes fluorescent only upon binding to the DNA of dead cells. Cells grown in black-wall plates can be stained and quantified in less than two hours. The assay is more robust and accurate than the other viability assays. It can be readily adapted for a wide variety of fluorescence platforms such as microplate assays, fluorescence microscope, and flow cytometry. The kit provides all the essential components with an optimized assay protocol. It is suitable for both proliferating and non-proliferating cells (either suspension or adherent cells). This Cell Meter™ Cell Viability Assay kit comes with sufficient reagents to perform either 200 assays (96-well format) or 800 assays (a 384-well format).

Cat # Size Storage Condition
22841 1 kit < - 15 oC
The cell cycle has four sequential phases: G0/G1, S, G2, and M. During a cell’s passage through cell cycle, its DNA is duplicated in S (synthesis) phase and distributed equally between two daughter cells in M (mitosis) phase. These two phases are separated by two gap phases: G0/G1 and G2. The two gap phases provide time for the cell to grow and double the mass of their proteins and organelles. They are also used by the cells to monitor internal and external conditions before proceeding with the next phase of cell cycle. The cell’s passage through cell cycle is controlled by a host of different regulatory proteins.
This particular kit is designed to monitor cell cycle progression and proliferation by using our proprietary Nuclear Green™ LCS1 in per-meabilized and fixed cells. The percentage of cells in a given sample that are in G0/G1, S and G2/M phases, as well as the cells in the sub-G1 phase prior to apoptosis can be determined by flow cytometry. Cells stained with Nuclear Green™ LCS1 can be monitored with a flow cytometer at Ex/Em = 490 nm/520 nm (FL1 channel).

Jurkat cells were treated without (red) or with 20 μM camptothecin (blue) in a 37 oC, 5% CO2 incubator for about 8 hours, and then loaded with Nuclear Green™ LCS1 for 60 minutes. The fluorescence intensity of Nuclear Green™ LCS1 was measured with a FACSCalibur flow cytometer in FL1 channel. In growing Jurkat cells, nuclear stained with Nuclear Green™ LCS1 shows G1, S, and G2 phases (red). In camptothecin treated apop-totic cells (Blue), both S and G2 phases were diminished.

In normal cells, DNA density changes depending on whether the cell is growing, dividing, resting, or performing its ordinary func-tions. The progression of the cell cycle is controlled by a complex interplay among various cell cycle regulators. These regulators activate transcription factors, which bind to DNA and turn on or off the production of proteins resulted in cell division. Any misstep in this regulatory cascade causes abnormal cell proliferation which underlies many pathological conditions, such as tumor formation.
This particular kit is designed to monitor cell cycle progression and proliferation using Nuclear Red™ CCS1, a cell cycle stain in fixed cells. The dye passes through a permeabilized membrane and intercalates into cellular DNA. The signal intensity of Nuclear Red™ CCS1 is directly proportional to DNA content after RNA is degraded by RNase provided in the kit. The percentage of cells in a given sample that are in G0/G1, S and G2/M phases, as well as the cells in the sub-G1 phase prior to apoptosis can be monitored with a flow cytometer at Ex/Em = 490/620 nm (FL2 channel).

Chloride channels have a variety of important physiological and cellular functions that include regulation of pH, volume homeo-stasis, organic solute transport, cell migration, cell proliferation and differentiation. Chloride channels represent valuable drug targets. A number of chronic diseases such as cystic fibrosis and Bartter’s syndrome are due to defects in chloride channel functions. However, the existing technologies used to screen chloride channel modulators have to compromise between throughput, sensitivity and physiological relevance.
Screen Quest™ Colorimetric Chloride Channel Assay Kit provides a sensitive and robust colorimetric method for the study of chloride channels. The assay is based on our proprietary iodide indicator (Iodide Blue™) to measure iodide concentration, as low as 100 nM of iodide can be detected. Iodide Blue™ forms a blue complex with iodide, which has absorption spanning from the UV to 700 nm. Thus a few absorption wavelengths can be used for monitoring the iodide-dependent color change. Screen Quest™ Colorimetric Chlo-ride Channel Assay Kit provides an optimized assay for monitoring chloride channels. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format.

11503 1 kit < - 15 oC
Hydrogen peroxide (H2O2) is a reactive oxygen metabolic by-prod-uct that serves as a key regulator for a number of oxidative stress-related states. It is involved in many biological events that are linked to asthma, atherosclerosis, diabetic vasculopathy, osteoporosis, a number of neurodegenerative diseases and Down’s syndrome. The measurement of this reactive species is helpful for determining how oxidative stress modulates various intracellular pathways.
This Amplite™ Intracellular Fluorimetric Hydrogen Peroxide Assay Kit uses our unique ROS Green™ hydrogen peroxide sensor to quan-tify hydrogen peroxide in live cells. ROS Green™ is cell-permeable, and generates the green fluorescence when it reacts with hydrogen peroxide. The kit is an optimized “mix and read” assay format that is compatible with HTS liquid handling instruments. The Amplite™ Intracellular Fluorimetric Hydrogen Peroxide Assay Kit provides a sensitive, one-step fluorometric assay to detect as little as 0.3 nanomoles of H2O2 in a 100 µL assay volume (3 µM). The assay can be performed in a convenient 96-well or 384-well microtiter-plate format. Its signal can be easily read by either a fluorescence micro-plate reader at Ex/Em = 490/520 nm for H2O2 detection in solution or a fluorescence microscopy for live cell H2O2 imaging.

Screen Quest™ Fluorimetric MDR Assay Kits

36340 1 plate < - 15 oC
36341 10 plates < - 15 oC
Multi-drug resistance (MDR) is a major factor in the failure of many forms of chemotherapy. In the past few years it has become widely accepted that the resistance to chemotherapy correlates with the overexpression of at least two ATP-dependent drug-efflux pumps. These cell membrane proteins, called P-glycoprotein (Pgp, MDR1), and multidrug-resistance-associated protein (MRP1) are members of the ABC transporter family. Our Screen Quest™ Fluorimetric MDR Assay Kits use a fluorescent MDR indicator for assaying these two MDR pump activities. This hydrophobic fluorescent dye molecule rapidly penetrates cell membranes and becomes trapped in cells. Following a short incubation, the intracellular free dye concentra-tion can increase significantly. In the MDR1 and/or MRP1-expressing cells this dye is extruded by the MDR transporters, thus decreasing the cellular fluorescence intensity. However, when its extrusion is blocked by an agent that interferes with the MDR1 and/or MRP1 pump-activity, its cellular fluorescence intensity increases signifi-cantly. The Screen Quest™ Fluorimetric MDR Assay Kits are ideal for high throughput screening of MDR pump inhibitors or identifying the cells that have high level of MDR pump activities.
Figure 7.39. Effect of Cyclosporin A on the inhibition of Pgp pump in MCF-7/ADR cells. The increased concentration of Cyclosporin A resulted in an increase in fluorescence signal caused by the inhibition of Pgp pump which enhanced the intracellular accumulation of MDR indicator dye. The EC50 = 2.4 μM (measured with the kit) is similar to the value reported in the literature.

Membrane potential is the difference in voltage between the interior and exterior of a cell. The membrane potential allows a cell to function as a battery, providing power to operate a variety of "molecular devices" embedded in the membrane. In electrically excitable cells such as neurons, membrane potential is used for transmitting signals between different parts of a cell. Opening or closing of ion channels at one point in the membrane produces a lo-cal change in the membrane potential, which causes electric current to flow rapidly to other points in the membrane. Ion channels have been identified as important drug discovery targets.
Our Screen Quest™ Membrane Potential Assay Kit is a homo-geneous assay with fast read time. It uses our proprietary long wavelength membrane potential indicator to detect the membrane potential change that is caused by the opening and closing of the ion channels. The red fluorescence of the membrane potential indicator used in the kit has enhanced fluorescence upon entering cells and minimizes the interferences resulted from the screening compounds and/or cellular autofluorescence.

HEK cells tran-siently transfected with P2X receptor were seeded overnight at 40,000 cells/100 µL/well in a 96-well black wall/clear bottom costar plate. The cells were incubated with 100 µL of the MP dye-loading solu-tion in a 5% CO2, 37 oC incubator for 60 minutes. ATP (50 µL/well) was added by FlexStation to achieve the final indicated concentrations. The fluorescence signal was measured using the bottom read mode at Ex/Em = 620/650 nm (cutoff at 630 nm).

Cell Meter™ JC-10 Mitochondrial Membrane Potential Assay Kit *Optimized for Flow Cytometry*
Cat # Size Storage Condition
22801 1 kit < - 15 oC
Although JC-1 is widely used in many labs, its poor water solubility causes great inconvenience. JC-10 is developed to be a superior alternative to JC-1. Compared to JC-1, JC-10 has much better water solubility. JC-10 is capable of selectively entering into mitochondria, and reversibly changes its color from green to orange as membrane potentials increase. When excited at 490 nm, the color of JC-10 changes reversibly from green to orange as the mitochondrial membrane becomes more polarized. Both colors can be detected using the filters commonly mounted in all flow cytometers. The green emission can be analyzed in fluorescence channel 1 (FL1) and orange emission in channel 2 (FL2).
This kit is based on the detection of the mitochondrial membrane potential changes in cells by the cationic, lipophilic JC-10 dye. In normal cells, JC-10 concentrates in the mitochondrial matrix where it forms red fluorescent aggregates. However, in apoptotic and necrotic cells, JC-10 exists in monomeric form and stains cells green. The kit is optimized to screen both apoptosis activators and inhibi-tors using flow cytometry while Kit 22800 is offered for microplate-based high throughput screening applications.

This Cell Meter™ JC-10 Mitochondrial Membrane Potential Assay Kit enables researchers to run JC-10 assay in the format of microplate reader, and it provides the most robust assay method for monitor-ing mitochondria membrane potential changes. The kit is based on the detection of the mitochondrial membrane potential changes in cells by the cationic, lipophilic JC-10 dye. In normal cells, JC-10 con-centrates in the mitochondrial matrix where it forms red fluorescent aggregates. However, in apoptotic and necrotic cells, JC-10 diffuses out of mitochondria. It changes to monomeric form and stains cells in green fluorescence. The kit can be used to screen both apoptosis activators and inhibitors. The assay can be performed in a conve-nient 96-well and 384-well fluorescence microtiter-plate format.

E. coli β-galactosidase is a 464 kD tetramer. Each unit of β-galactosidase consists of five domains, the third of which is the active site. It is an essential enzyme in cells. Deficiencies of this enzyme can result in galactosialidosis or Morquio B syndrome. In E. coli, β-galactosidase is produced by the activation of LacZ operon. Detection of LacZ expression has become routine to the point of detection of as few as 5 copies of β-galactosidase per cell.
This kit uses the fluorogenic fluorescein digalactoside (FDG) galac-tosidase substrate that can sensitively distinguish LacZ+ from LacZ- cells. The non-fluorescent substate generates the strongly fluores-cent fluorescein upon reaction with galactosidase. It can be used either for detecting galactosidase conjugates in ELISA type assay systems or for monitoring LacZ gene expression in cells. FDG used in the kit is not fluorescent. The galactosidase induced cleavage of FDG gives fluorescein that has the spectra of Ex/Em = 490/515 nm, which can be detected with most fluorescence instruments equipped with a FITC filter set. The kit comes with all the essential components with an optimized assay protocol. It can be used with a fluorescence microplate reader, a fluorescence microscope, or a flow cytometer. It might also be used for screening galactosidase inhibitors or inducers.

The most versatile reporter gene is the firefly luciferase. Recently there is steadily increasing use of other luciferases, such as Gaussia luciferase since these reporters are smaller and do not require the presence of ATP. The bioluminescent enzyme derived from the marine copepod Gaussia prince is efficiently secreted from mam-malian cells upon expression. Gaussia luciferase is a 20kDa protein which catalyzes coelenterazine oxidation by oxygen to produce light. Our Amplite™ Gaussia Luciferase Reporter Gene Assay Kits use a proprietary luminogenic formulation to quantify luciferase activity in cell medium. The formulation generates a luminescent product that gives strong luminescence upon interaction with Gaussia luciferase. The kits provide all the essential components that are compatible with HTS liquid handling instruments. They have high sensitivity and can be performed in a convenient 96-well and 384-well microtiter-plate format. The “glow-type” signal with a half-life of one hour provides a consistent signal across large number of assay plates. The assay is compatible with standard cell growth media.

Amplite™ Luciferase Reporter Gene Assay Kits *Bright Glow*

12520 100 plates < - 15 oC
The most versatile and common reporter gene is the luciferase of the North American firefly photinus pyralis. The protein requires no posttranslational modification for enzyme activity. It is not even toxic in high concentration (in vivo) and can be used in pro- and eukaryotic cells. These Amplite™ Luciferase Reporter Gene Assay Kits use a proprietary luminogenic formulation to quantify lucifer-ase activity in live cells and cell extracts. The assay is based on firefly luciferase, a monomeric 61 kD enzyme that catalyses a two-step oxidation of luciferin, which yields light at 560 nm. Our formulation generates a luminescent product that gives strong luminescence upon interaction with luciferase. The kits provide all the essential components with our optimized “mix and read” assay protocol that is compatible with HTS liquid handling instruments. They have high sensitivity and can be used for the assays that require low detec-tion limit. The kits have a fast, simple, and homogeneous biolu-minescence assay for studying gene regulation and function. The “glow-type” signal with a half-life of two to four hours provides a consistent signal across large batches of plates. The assay is compat-ible with the use of standard cell growth media.

12537 100 plates < - 15 oC
Common reporter genes include beta-galactosidase, beta-gluc-uronidase and luciferase. The most versatile reporter gene is the firefly luciferase. Recently there is steadily increasing use of other lu-ciferases, such as Renilla luciferase since these reporters are smaller and do not require the presence of ATP.
Our Amplite™ Renilla Luciferase Reporter Gene Assay Kit is designed to provide a fast and sensitive method to detect the luciferase from sea pansy (Renilla reniformis). It uses a proprietary luminogenic for-mulation to quantify Renilla luciferase activity in cell-based assays. Our formulation generates a luminescent product that gives strong luminescence upon interaction with Renilla luciferase. The kit pro-vides all the essential components. It has high sensitivity and can be performed in a convenient 96-well and 384-well microtiter-plate format. The “glow-type” signal with a half-life of one hour provides a consistent signal across large number of assay plates. The assay is compatible with standard cell growth media. This kit enables the measurement of primary expression or gene expression with wild type and the synthetic hRluc genes .
Figure 8.3. Luciferase dose response was measured with Amplite™ Luciferase Reporter Gene Assay Kit. The kit can detect as low as 0.1pg/well luciferase with 20 minutes to 5 hours incubation time without losing signal intensity. The integration time was 1 sec. The half life is more than 4 hours.
