Welcome to the latest issue of the Tecan Journal

Tecan has a long history and tradition in the OEM market and, as we move into the fall, we celebrate the milestone 40th anniversary of Cavro®. For four decades, instrument designers have relied on Tecan Cavro branded components to provide innovative and reliable liquid handling products that can be applied to a wide range of applications. As part of Tecan’s broad OEM product portfolio – from components such as pumps, valves and robotic modules, to full system solutions and instruments that partners incorporate with their specific applications and tests – the Cavro brand is a key element in the Company’s success as the ‘OEM partner of choice’ for leading diagnostic and life science companies.

We continue to enhance and broaden the functionalities of the market-leading Freedom EVO® liquid handling platform with new modules and applications. The launch of the new Air LiHa air displacement pipetting arm – which provides greater versatility than ever before – is generating a lot of interest and, to help meet ever-increasing quality and regulatory demands, we have recently released the QC Kit, offering a total solution for liquid handling performance verification testing.

Tecan US relocates to bigger and better premisesJuly this year saw Tecan US relocate from the Durham premises it had occupied for the past 21 years to a new, larger facility in the nearby Morrisville area of Raleigh. This new base offers scalable space and additional training rooms to meet the needs of continued growth over the coming years. With its high ceilings and clean lines, the new building has a very modern and sleek appearance, providing a pleasant environment for visitors and employees alike. Situated close to Raleigh-Durham International Airport, hotels, restaurants and shopping at Brier Creek, the new premises are convenient for both customers attending the Company’s training facility and commuting employees.

Careful planning enabled the relocation to be completed over the course of one weekend, as Peter Hornbach, Vice President of Operations, explained: “We closed slightly early on the Friday, and moved the IT portion of the business that evening. That was followed by 64 truckloads of equipment and, by mid afternoon on Saturday, we had actually moved everything in. We cleaned up on Sunday, and

The Cornell Cup USA is an embedded design competition created to empower student teams to become inventors. Sponsored by Intel, the competition was run for the first time this year, and is based on the success of the Intel China Cup, which attracts entries from over 26,000 students. Held in May at Walt Disney World’s Contemporary Resort on Lake Buena Vista, Florida, the MIT’s entry in the competition was supported by Tecan. Dr Jonathan Babb, advisor of the MIT team, explained: “Five of our students entered the Cornell Cup USA as ‘Team Squirtle’, with $500 sponsorship from Tecan for their expenses. The team’s project brief was to design and build a smaller, lower priced and more intelligent liquid handler that would provide individual researchers with a tool for fast, accurate and tailored pipetting to meet their liquid handling needs. The students had considered making their own pump, but identified that this key component of their custom liquid handler would be very challenging to build in the time available. As Tecan was already sponsoring the team, we asked if we could use one of the Company’s pumps. We were kindly lent a Cavro XCalibur Pump (XC Pump), and the students were shown how to set up and use it.”

Jonathan continued: “Tecan’s help was invaluable, making it easy for the students to integrate the pump and connect it to their software. This allowed the team to focus on the innovative aspects and architecture of the robot, creating a system that is quite different from conventional liquid handling instruments. Their solution was a delta parallel robot with three jointed arms coming together into a point. The arms are each controlled by a servo and motor, allowing the user to determine the exact location

of the pipetting tip. This design, which was inspired by the high-speed, pick and place assembly line robots used in the electronics industry to position chips on circuit boards, came third overall, winning a prize of $2,500. The project was all about making one tip go faster, rather than adding more tips as in conventional liquid handling systems, and we are grateful to Tecan for its support.”

Tecan showcases the Freedom EVO® workstation configured for ELISAs to delegates visiting from Chinese blood centersDelegates from blood centers across China recently enjoyed a visit to Tecan’s European development facilities in order to share their experiences and give their input on performing high quality ELISAs within blood banking laboratories. Tecan demonstrated a Freedom EVO workstation specifically configured to meet the ELISA throughput demands observed in the Chinese clinical market, incorporating a range of features to streamline the blood testing workflow.

Efficient throughput is critical in hospital and blood center laboratories, requiring reliable automated solutions which are closely matched to laboratory workflows. The Freedom EVO offers a flexible configuration which can be tailored to individual throughput requirements, with a choice of either one or two liquid handling arms, up to two HydroFlex™ microplate strip washers, a Robotic Manipulator (RoMa) Arm for plate transportation and an Infinite® F50 microplate reader. The specific requirements of the scientist’s assay can be fulfilled by the use of a variety of incubators, hotels and carriers, providing complete automation of the processing workflow.

The Freedom EVO is controlled by Tecan’s intuitive Freedom EVOware® software, and uses the TouchTools Suite™ graphical user interface (GUI) to simplify day-to-day operation of the instrument. Combined with Tecan’s new QC Kit for liquid handling performance verification testing, this flexible solution provides hospitals and blood centers in China with a straightforward and efficient way of automating testing.

The visit was arranged in response to increasing demand for automated laboratory systems in Chinese hospitals and blood centers, and reflects Tecan’s close collaboration with customers. This year’s event built on the success of the previous visit to Tecan’s Männedorf headquarters in Switzerland in 2010. In addition to seeing Tecan automation in action, delegates were given the opportunity to visit Tecan manufacturing sites in both Männedorf and Salzburg, Austria, as well as a visit to a Zurich blood bank to foster relations and exchange blood bank practices. The visit also included workshops on various aspects of potential

development, providing customers and Tecan specialists with an opportunity to discuss current and future applications, as well as the bottlenecks in processing, helping to drive forward identification of novel solutions for this important market.

TES Pharma is a small biotechnology company based in Corciano near Perugia, Italy, specializing in compound screening for pharmaceutical drug discovery. Combining an in-depth knowledge of drug design and chemistry with systems and molecular biology approaches, the Company works collaboratively with partners around the world to combine the best aspects of academia and commercial pharmaceutical development.

TES Pharma’s small yet highly skilled and experienced team works closely with the University of Perugia to rapidly develop and explore novel compounds which may be of interest in various disease states. To standardize the Company’s workflow, as well as to free up more staff time for research activities, TES Pharma has recently invested in an HP D300 Digital Dispenser from Tecan. Graeme Robertson, a co-founder of TES Pharma, explained: “The drug discovery process is becoming increasingly highly specialized, often involving multiple partners with distinct skill sets working together to deliver novel therapeutic agents. Our core competence at TES Pharma lies in the development of advanced screening assays, and we believe that, by working closely with academic partners with expertise in individual conditions or disease areas, we can eliminate some of the drawbacks inherent in traditional drug discovery pipelines.”

“To do this we need to concentrate on our own expertise in core areas, and our HP D300 Digital Dispenser allows us to use our time more effectively, without compromising on results. As a small collaborative research facility we do not have a high enough throughput to effectively use complete laboratory automation systems,

but the HP D300 is easy to use and its precision dispensing eliminates the need for tedious manual dilutions. Digital titration also offers several key advantages over traditional manual protocols in terms of reducing waste of valuable compounds, limiting the DMSO content for sensitive assays and increasing reproducibility, but it is the staff time it creates that is most important, liberating skilled individuals to perform more exploratory research. It also allows us to limit the number of variables in a way that would not be possible manually, helping us to rapidly characterize novel biological activities which might otherwise be missed.”

The Experimental Nephrology laboratory of the Department of Internal Medicine D at the University Hospital of Münster (Universitäts Krankenhaus Münster – UKM), Germany, has used Tecan’s Infinite 200 PRO microplate readers to further develop its cell-based techniques for the investigation of cell membrane transport in the proximal tubules of the kidney. The team has established a novel ex vivo fluorescence technique which enables parallel analysis of numerous samples in a 384-well microplate format, making this type of study far easier to perform, while significantly increasing the number of experiments which can be carried out with a limited amount of biological material. Svenja, a medical student at UKM, explained: “Organic cation transporters (OCTs) are crucial for the renal excretion of endogenous organic cations such as the monoamine neurotransmitters dopamine and noradrenaline, as well as the 40-50 % of pharmaceutical drugs that are positively charged. Until now, organic cation transporters could only be examined using time-consuming fluorescence or radiotracer methods; the technique and set-up procedures were very tedious. We have successfully used our Infinite 200 PRO readers – we have both an Infinite M200 PRO and an Infinite F200 PRO – to develop a microplate reader-based method that can be adapted to almost any kind of freshly isolated biological material and transport system by using a suitable fluorescent substrate. The method enables us to study OCTs in freshly isolated proximal tubules of mouse kidneys, an ex vivo environment, and has significantly increased

our throughput, as we can now place three proximal tubules in each well of a 384-well plate, depending only on the isolation capacity.”

The properties and regulatory mechanisms of organic cation transport in proximal tubules of mouse kidneys are of particular interest with regard to the emerging role of transgenic mouse models in pharmacological, physiological or pathophysiological studies. Svenja continued: “We investigated the dynamics of organic cation transport by flux experiments with a fluorescent transporter substrate, ASP+, which undergoes a shift in the emission spectrum from 550 nm to 590 nm when it is transported into cells. Each individual well of a 384-well microplate accommodates three segments of freshly isolated mouse proximal tubules, each approximately 200 µm long. ASP+ is added to each well, and the increase in cellular fluorescence is recorded. By making fluorescence measurements, we can quantify cellular accumulation of ASP+, which is proportional to the extent of organic cation transport. We can also take advantage of the Infinite 200 PRO’s dual injection module to study the properties of OCTs to determine the affinities of known or unknown substrates; substrates with high affinities to organic cation transporters will inhibit the uptake of ASP+. The method also allows us to screen for substrates and drugs which interfere with OCTs, which may open new therapeutic approaches to reducing drug-induced damage of the kidney by nephrotoxic drugs.”

A winning combination for nephrology research In the last edition of the Tecan Journal we announced the winner of the Tecan Award 2011, Svenja Kristina Holle from the University Hospital of Münster, whose team has developed an ex vivo method for investigating the dynamics of organic cation transport in proximal tubules of the kidney, using an Infinite® 200 PRO microplate reader.

“ We can now study 100 assays at one time, which has increased the number of experiments that can be carried out with one animal enormously.”

Previously, UKM’s Experimental Nephrology laboratory analyzed the dynamics of OCT processes using an inverted fluorescent microscope imaging system, but this restricted measurement to a very small number of isolated tubule segments per kidney and animal, due to tedious and time-consuming set-up procedures for each segment. “The new method is far easier to use, and does not require a lengthy training period. Before, we could only examine one tubule at a time using the inverted microscope, but the new microplate reader-based technique allows us to perform several assays in parallel. We can now study up to 300 assays at one time, which has increased the number of experiments that can be carried out with one animal enormously; this is a huge advantage and has significantly reduced both the time and cost of experiments,” concluded Svenja.

As the 2011 winner of the Tecan Award, Svenja’s prize was a weekend in the romantic city of Salzburg, which included a tour of Tecan’s Detection Headquarters in Grödig, Austria. Svenja described her visit to Austria: “Our trip to Salzburg began with a short visit to Tecan’s production site on Friday morning. It was really interesting for me to see the inside of the microplate reader that I’ve worked with for such a long time, and to hear about other promising developments at Tecan. I gave a presentation about my research, and I really appreciated everybody’s interest in my work; we had a valuable discussion and I received some really good suggestions for improving our technique even further.”

“Afterwards, it was a great honor for me to receive the Tecan Award. The rest of the weekend was spent enjoying the sights of Salzburg. Of course, we took the hard climb up to Hohensalzburg Castle, where we were rewarded with an amazing view over the city and the panorama of the Alps. We also loved having the delicious breakfast in our fantastic hotel right beside the Salzach, the river which parts Salzburg into its historic city centre and the new town. All in all, we will always remember our great weekend trip to Salzburg with a smile!”

Isogenica Ltd, based at Chesterford Research Park near Cambridge, UK, specializes in the discovery, identification and design of new therapeutic peptides, proteins and antibodies for pharmaceutical and biotechnology companies. The Company’s proprietary technology – CIS display – enables rapid library construction and selection, generating faster hits and better leads to reduce discovery time and improve the quality of candidate options. To meet the demand for higher throughput, Isogenica has purchased two Freedom EVO 200 platforms for the selection of next generation molecules and for running ELISAs. Neil Cooley, Operations Manager at Isogenica, explained: “Our clients provide us with a target molecule and we use our CIS display technology to discover binders to that target. We have automated this technology on the Freedom EVO platform to make it less labor-intensive and to increase our throughput, allowing us to do more of these selections in parallel.”

Tecan held comprehensive discussions with Isogenica to establish the Company’s exact needs and design the most appropriate platforms for their selection and ELISA protocols. Two Freedom EVO 200 workstations were chosen, each equipped with a Robotic Manipulator (RoMa) Arm, an eight-channel Liquid Handling (LiHa) Arm with low-volume disposable tips and a MultiChannel Arm™ (MCA) 96. The selection platform also has an integrated Infinite® F200 PRO multimode reader for PicoGreen® analysis of DNA levels,

an LPT 220 EVO™ Carousel, an extended Z-axis RoMa, low disposable tip ejector option and a dust cover, and is used to run a protocol based on the Company’s CIS display technology. This platform also takes advantage of Tecan’s SBS format disposable tip boxes, allowing large quantities of tips to be stored on the Carousel for increased walkaway times.

Neil continued: “Tecan offered a cost-effective solution and the Company has a good reputation; we also liked the training that was provided with the system. They took the time to get to know exactly what we needed and to ensure that we understood what options were available to us – and the advantages of each option – including presentations that explained the benefits of different semi-automated versus fully integrated systems. It was particularly tricky deciding whether to have everything integrated on the candidate selection platform or not, where to put all the options we needed and how to get the highest throughput.”

Although the Company has had the workstations for less than a year, the advantages of automating the selection protocol can already be observed. Automating the process enables multiple target molecules to be tested against a number of libraries under different selection conditions, offering the capability to multiplex across a 96-well plate. This provides more versatility

and improves consistency, which is an important consideration, as well as allowing many more selections to be performed than would be possible manually. The maximum number of selections that can be comfortably performed at one time manually is 12 to 16. In contrast, the microplate format used by the automated process enables 96 selections to be performed simultaneously.

Automation of the DNA/protein binding ELISA protocol on the Freedom EVO has also proved popular with staff, and has significantly increased Isogenica’s screening capacity. When the ELISA is semi-automated using 96-well plates, one person can process

“... the big advantage of automating the selection process is that it allows a larger number of selection conditions and different types of library – peptides, scaffolds or even antibodies – to be tested with their target molecule, providing them with greater choice.”

Isogenica provides peptide, protein and antibody discovery and design services to pharmaceutical and biotechnology companies, and has invested in two Freedom EVO® liquid handling platforms to increase its capacity for the selection of next generation molecules.

up to 48 plates a day. Automation has also enabled the Company to miniaturize its assays into 384-well plates, which allows many more clones to be screened with the same targets in the same time period. “We need to keep the amount of target used to a minimum, and moving to 384-well plates reduces the amount of material we need,” said Neil. “The platforms’ ease of use has also encouraged widespread use of the systems; staff became comfortable with operating the instruments very quickly. As a result, we have extended the functions that we currently carry out on the Freedom EVO beyond those initially envisaged.”

Isogenica’s clients also reap the benefits of automation. When a larger number of selections need to be performed, it is now possible to run one large batch of samples on the Freedom EVO, rather than several small batches manually, enabling more rapid and consistent delivery of peptide or protein candidates. “For our clients, the big advantage of automating the selection process is that it allows a larger number of selection conditions and different types of library – peptides, scaffolds or even antibodies – to be tested with their target molecule, providing them with greater choice,” concluded Neil.

Founded in 1921, the Central Tuberculosis Research Institute of the Russian Academy of Medical Science (CTRI RAMS), Moscow, is a global leader in the development and application of advanced techniques for the effective control of tuberculosis (TB). The Institute consists of nine research divisions, including four 400-bed clinical departments, and the Institute’s multidisciplinary research team studies every aspect of the diagnosis, pathology and transmission of TB.

Diagnosis of TB, and determination of antimicrobial sensitivity, generally takes 6 to 14 weeks using classical microbiological methods, delaying provision of appropriate treatment and contributing to the high TB-associated mortality rate in Russia. To reduce this lengthy detection time, the CTRI RAMS’ Department of Microbiology – led by Professor Larisa Chernousova – is investigating new approaches to improve the diagnosis of tuberculosis, including a novel genetic technique based on PCR (polymerase chain reaction). Larisa explained: “A vital step in this highly sensitive method is the extraction of DNA from patients’ sputum samples. This is a monotonous and labor-intensive process when performed manually, requiring high levels of concentration to avoid cross-contamination between samples and subsequent false positive results, and so is ideally suited to automation.”

Working in collaboration with Syntol – a specialized clinical diagnostic company in Russia – the Institute has developed an automated protocol that allows safe and effective handling of potentially highly contagious M. tuberculosis samples without the need for costly biosafety measures. This technique uses an inactivation buffer to kill any mycobacterium present, offering safe handling of patient material without compromising the quality of the extracted DNA. The workflow was initially developed on a Freedom EVO 75 before being transferred to the Department’s Freedom EVO 150 workstation. It includes dilution of the sputum samples and addition of the inactivation buffer using the instrument’s Liquid Handling (LiHa) Arm, magnetic extraction of the M. tuberculosis DNA from clinical samples and microbial cultures, transfer of the extracted genetic material to PCR tubes, and online PCR amplification.

Professor Chernousova continued: “Extraction of 48 samples takes just 95 minutes, allowing us to process up to 144 samples a day if required. Once the extraction process is complete, the recovered DNA is transferred directly to PCR tubes and automatically loaded onto a thermocycler for amplification. This provides true walkaway processing and significantly increases the laboratory’s throughput, while also lowering the cost per test.”

Protecting the nationRussia’s Central Tuberculosis Research Institute is using a Freedom EVO® workstation to help in the fight against tuberculosis. The platform provides fast and secure sample preparation, allowing molecular diagnosis of M. tuberculosis infection in just a few hours.

“Even a microdrop of aerosol containing genetic material could cause contamination in this process, but none of our negative controls showed amplification by PCR.”

Due to the high sensitivity of the PCR-based technique, minimizing the risk of errors and cross-contamination was crucial, and so the laboratory carried out rigorous testing and validation prior to bringing the Freedom EVO 150 platform into routine operation. “We were very happy with the performance of the system during our carry-over studies,” Larisa added. “Even a microdrop of aerosol containing genetic material could cause contamination in this process, but none of our negative controls showed amplification by PCR. We have also been impressed by the flexibility and open architecture of the platform, and now plan to use additional Tecan workstations for complete automation of our bacteriology workflows in the future – from preparation of reagents and media to culture seeding and incubation.”

In the first four months of operation, the laboratory has prepared over 500 clinical samples for analysis. The Freedom EVO workstation offers considerable time savings while reducing the labor required. “This helps the laboratory to identify the causative agent of a patient’s symptoms much faster, providing clinical staff with the right information to effectively treat patients far earlier,” Professor Chernousova concluded.

18 DRUG DISCOVERY TECAN JOURNAL 3/2012

In Japan, Osaka has been known as the city of medicine since the 17th century. The chemical industry, helped particularly by pharmaceutical companies, is today the most lucrative of Osaka’s industries and shows great promise for future growth. This setting is ideal for the International Drug Discovery Incubation Group at Osaka University’s Office for University-Industry Collaboration to serve as a shared-use facility funded by the Japan Science and Technology Agency (JST). The Group’s primary purpose is to accelerate collaborative research between academia and industry by directly supporting the drug discovery research activities of universities and businesses throughout the Kansai region of Japan.

Dr Yoon-Jeong Kim, Leader of the International Drug Discovery Incubation Group, explained how the thinking behind much of the Group’s strategy stems from the pharmaceutical industry’s ‘gap issue’.

“The whole process from hit discovery to final drug-to-market was traditionally handled within a pharmaceutical company. It would routinely take 15 to 20 years for a new target to be developed into a drug which would have a 25 year patent, resulting in the actual trading life of 10 years for that drug. In the early 2000s, an average candidate success rate was only one in ten thousand. As a result, pharmaceutical companies began to focus their activities on the later phases of drug development, to help them recover their investment more quickly. At the same time, they tried to extend the period of the patent of drugs that were already on the market by changing the drug formulation.”

“Universities continued to work on early stages of drug discovery and the discovery of new targets, but a gap between this work and the later development phases performed by pharmaceutical companies began to widen. As a result, there are very few new

candidates coming through the drug discovery portfolio. With a rush of patents having expired around 2010, many companies are now struggling to maintain a steady stream of business revenue.”

“This gap is a big problem throughout the pharmaceutical industry which must be addressed. We are tackling this issue head on by furnishing our laboratories with a variety of modern, high throughput instruments and employing methods that traditionally only pharmaceutical companies would have used.”

The Group has two Freedom EVO workstations: a Freedom EVO 100 used mainly for plate replication, and a custom-configured Freedom EVO 200 equipped with a Liquid Handling Arm, an integrated incubator, a Tecan Carousel HS™ for microplate logistics, a plate washer, and an Infinite M1000 microplate reader. This system is fitted with a

HEPA filter because many users are performing cell-based assays which require aseptic conditions. Plates are transferred automatically to the Infinite M1000 to collect the data for some assays, but both the reader and the plate washer can be used independently, even while the Freedom EVO 200 is performing unrelated tasks.

Dr Kim added: “These instruments are very popular, and are being used almost every day. Many scientists who use our facilities are performing high throughput (HT) methods for the first time and, as an organization dedicated to supporting research, we provide a substantial amount of specialized training as required. We teach various techniques from how to process compounds and set up cell-based assays to data collection, and we train researchers so that they can independently perform HT methods themselves. In reality, this probably forms the bulk of our work.”

Dr Kim had already had positive experience of working with Tecan’s liquid handling workstations from his earlier career in a major pharmaceutical company: “I remembered many strong advantages for using Tecan and I knew these would also be relevant for our Group here. Tecan has a lot of experience in the types of applications we were looking for. We wanted a HT robot that allows many tasks to be performed by a small number of people, and Tecan’s Freedom EVO workstation was chosen as a platform to fulfill this concept. We were confident that the Company and its instruments would be a good fit for our laboratory. Tecan’s technical staff members are constantly in touch to support us and ensure that the instruments are working as efficiently and reliably as possible.”

He concluded: “In the future, we plan to develop our group with the addition of more instruments that would benefit researchers

who use the Incubation Group’s facilities. Clearly, if we stick to the old ways of doing things, we will inevitably meet difficulties. There are always processes that need new techniques to push them forward and, with a broad range of innovative instruments, we are working to build a set-up that will do just that.”

Biobanks such as the IBBL have a vital role to play in modern medical research, providing high quality biospecimens, as well as the technology and scientific expertise to enable researchers to evaluate data against medical records and environmental factors. The IBBL was established following a 2008 Government agreement to form a strategic partnership with three US research centers – the Translational Genomics Research Institute (TGen), the Institute for Systems Biology and the Partnership for Personalized Medicine. Working closely with the Luxembourg Personalized Medicine Consortium (PMC), the IBBL collects, stores, and analyzes biological samples and associated clinical

data, from neighboring countries as well as Luxembourg itself, which are then made available to research organizations. In addition to somatic disease collections for cancer, type 2 diabetes and Parkinson’s disease research, there is also a normal population cohort collection from healthy people – a collaboration with CRP Santé – that acts as a control.

Today, through its own investigations and partnerships with internationally recognized research centers, the IBBL’s world-class scientists are at the forefront of innovative biospecimen research. Fay Betsou, Chief of Biospecimen Science at the IBBL, commented: “Research often tends to focus on biomarker identification and validation rather than specimen validation, but this is a basic critical issue that could completely invalidate experimental results. Innovative biospecimen research is a very important – yet extremely rare – initiative that is quite specific to the IBBL.”

The IBBL’s biospecimen collection and biorepository contain high quality tissues and body fluids, maintained according to strict quality requirements. The associated biorefinery analysis and research service produces high quality analytes, such as DNA, RNA and protein, maintains technology for high throughput gene sequencing and gene expression, and conducts biospecimen research. In addition, an informatics platform securely maintains clinical and biospecimen data.

A key target biospecimen for IBBL and many biobanks and diagnostic laboratories is the buffy coat, the layer of leukocytes and platelets that forms when unclotted blood is centrifuged or allowed to stand, and is often used for DNA extraction. Traditionally, the process of manually isolating the buffy coat from whole blood is slow, tedious and very dependant on the skill and dexterity of the technician separating the layers. To eliminate this time-consuming and variable element of sampling, the IBBL and Tecan joined forces to co-develop an automated procedure on a Freedom EVO 200 platform.

Fay explained: “Our sample throughput, although relatively low at present, is expected to increase five-fold in the near future, and we were initially looking for a flexible liquid handling system that could meet this demand. We also have particularly strict requirements

Rapid, automated isolation of buffy coat benefits DNA extraction

Tecan and the Integrated BioBank of Luxembourg (IBBL) have successfully co-developed an automated platform for buffy coat extraction based on a Freedom EVO® 200 workstation, relieving scientific staff from this time-consuming task and significantly increasing the yield of DNA.

in terms of time; it is crucial to minimize the delay between sample collection and freezing, and speed is essential. We looked at the existing options and spoke to several different suppliers before choosing Tecan. From the beginning, we could see that as well as performing classical liquid handling, there was a real possibility of automating buffy coat extraction using the Freedom EVO. This was never going to be an easy process, largely because of the variation in individual sample volumes and the quantity, viscosity and texture of the buffy coat layer itself, but we had several meetings with Tecan’s technical teams and, over the next couple of months, worked together to co-develop an automated method.”

collection tubes are placed on the Freedom EVO platform, which is equipped with Robotic Manipulator (RoMa), eight-channel Liquid Handling (LiHa) and Pick and Place (PnP) Arms, a Tube Inspection Unit (TIU), an Xtr-96 flatbed scanner (FluidX), Xsd-96Pro and Xsd-48Pro modules (FluidX), and a BDK module to provide HEPA-filtered air on the worktable. The workstation, which is also used for aliquoting serum, plasma and urine, has been optimized to maximize the yield and quality of the buffy coat, and to minimize the risk of cross-contamination. Tubes are transferred to the TIU, which identifies the position of the buffy coat layer using a laser beam. The buffy coat is then aspirated by the LiHa using a spiral movement, and transferred to its destination tube. “The LiHa pipettes the buffy coat layer with very precise orientation and speed, standardizing the process and eliminating technician-to-technician variation,” Fay added.

During the validation process, IBBL found the automated system gave a purer buffy coat product with less contamination from red blood cells and hemoglobin and a similar distribution of white blood cells, as well as an average DNA yield significantly higher than that obtained by manual extraction. “The results are amazing; the yield is 10-15 % higher using the automated process. Altogether, isolating the buffy coat manually is a tortuous task but the Freedom EVO system now processes 24 samples in just 16 minutes. We are very satisfied with the system and are looking forward to working with Tecan on another biospecimen research project in the near future,” concluded Fay.

22 GENOMICS TECAN JOURNAL 3/2012

Genetic circuits are an exciting area of synthetic biology, with potential applications in areas as diverse as biofuel production and medicine. These plasmid constructs have the ability to regulate the function of host bacterial, yeast or mammalian cells, reprogramming them to produce novel substances, change appearance or exhibit different behavior. Researchers in the Synthetic Biology Center at the Massachusetts Institute of Technology (MIT), USA, are working on several collaborative projects to develop genetic circuits for a variety of applications. Dr Jonathan Babb, a researcher at MIT, explained: “If you think about it in engineering terms, we are building a machine by taking specific DNA sequences and putting them together in different combinations to form genetic circuits. A collection of these circuits can then be loaded into a host cell, reprogramming it. The Weiss Laboratory at MIT recently published an example of this approach, where a genetic circuit triggers apoptosis in cancer cells, but not in healthy cells, offering diagnosis and treatment in one step. Another potential application is in biofuel development, re-engineering bacteria to efficiently produce fuels such as biodiesel.”

“Although we use a modular approach, development of these genetic circuits is still very time-consuming and labor-intensive, and so we purchased a Freedom EVO 150 platform to meet our liquid handling needs. This platform effectively transforms what is already done in electronics – pushing buttons to activate software and hardware to produce the desired circuit – to our synthetic biology experiments. Scaling up this process on a robotic system also gives us higher throughput and repeatability without the variability inherent in manual procedures.”

“We specifically chose a Tecan system for this application because the software and hardware are easy to extend, and we wanted the flexibility to experiment with different combinations of modules. The Freedom EVOware® software has an open architecture, making it easy to write and develop scripts and connect the instrument to our own systems and software, and the design of the hardware undoubtedly helps with the integration of our own modules and apparatus onto the worktable. For example, we wanted to be able to store enzymes at -20 oC on the deck, and were able to get an

automation-friendly chiller that could do this at fairly low cost, without having to make any major modifications to the platform.”

“We have also been able to devise our own colony picking procedures for cell-based screening, and to set up and run an ordinary, low-cost gel station on the platform. The Freedom EVO is able to automatically load and run gels on the gel station, despite the lack of a communication port on this device, eliminating the need for a lot of expensive additional hardware. The flexibility and programmability of the Freedom EVO are invaluable for this, allowing us to rapidly develop in-house solutions and create the elaborate algorithms that are required to perform the many different steps necessary for the assembly of genetic circuits. We have successfully demonstrated that every step in the process can be automated and run completely unattended, and are now scaling up to high throughput mode, which will see multiple 96-well plates processed per day.”

“Tecan’s technical expertise has also been important to the success of our work, and we receive excellent application support from the Company. My colleagues and I attended a Tecan users’ meeting in Boston last October, specifically to find a solution to the complex issue of pipetting minute volumes of our suspensions on the Freedom EVO platform with the existing liquid classes. Tecan’s application specialists were able to give us a new liquid class that would not only be able

to handle the volume and viscosity we wanted, but also direct the pipette tip to twist around and tap the side of the vessel, so that any drop of liquid would come off. We also have very good ongoing support from Tecan locally – for general advice and troubleshooting – and are kept up-to-date with new technologies and solutions which could further our research.”

Go2 Technologies in Dayton, Ohio, USA, has taken advantage of state-of-the-art manufacturing and engineering technology, combined with leading-edge robotics and the Cavro Air Displacement Pipettor (ADP), to establish an innovative automated process for sonochemical synthesis of nanoparticles for the generation of hydrogen gas. Sonochemical synthesis – chemistry driven by ultrasound waves – relies on high intensity sound waves, which are only present near a powerful sonic probe. This makes it difficult to perform large-scale reactions and, as a result, chemists are usually forced to perform labor-intensive batch procedures consisting of numerous small syntheses. To automate these procedures – and decrease labor costs significantly – Go2 Technologies has developed the RADS robotic synthesis machine. Kent Walker, Partner/Owner at Go2 Technologies, explained: “The University of Dayton Research Institute and the Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio, were creating air-stable organically-capped aluminum nanoparticles for the production of hydrogen gas from water, which involved manually pipetting three different materials – alane, titanium isopropoxide, and oleic acid – inside a glovebox. This is a very labor-intensive procedure for a single operator, and we were approached to develop an automated method that could robotically dispense, mix, sonicate and verify, essentially to produce a robotic synthesis machine to automate the manual pipetting and dispensing stages within the enclosure.”

“The really big challenge of the whole process was liquid dispensing; we needed something compact and lightweight that could cover a large range of volumes, from 15 µl to 10 ml. Some of the chemicals used are pretty harsh on plastics, and pumping these materials through a mechanical piece of equipment was causing them to degrade and break down quickly. This was where the Cavro ADP really came into play. We looked at standard dispensing-type pumping systems but, typically, these wanted to bring the liquids into the device. The nature of the liquids used meant that we needed to find a non-contact mechanism for dispensing and pumping, with tips that were either disposable, or could be removed and replaced during the process.

Accurate, reliable dispensing of liquid volumes was also vital. I had previous experience with Tecan and was familiar with its products, so we approached Tecan Systems. The Cavro ADP was the key to making the whole dispensing process happen because it doesn’t touch the liquid, it just brings it into the end of a disposable pipette tip.”

Kent continued: “The system design is unique. Unlike the more standardized XYZ robotic components, the Cavro ADP is free standing and is manipulated by a Mitsubishi vertical articulating robotic arm. The Cavro ADP needed to be used as a pick and place-type unit rather than being permanently mounted, so we created custom fixtures and tools from

which the robotic arm could pick it up when required. We use the Cavro ADP with Tecan’s disposable tips, and have modified the tip racks to fit our application. Each of the liquids that we pipette has its own rack of tips and, once they have been used, we just dispense them into a waste container within the purge box. All these adaptations had to be extremely precise, to ensure that everything worked reliably and reproducibly.”

“As well as implementing the robotic solution, we had to develop a custom airtight chamber that could be purged with nitrogen. After talking to several vendors about the inner chamber we realized that these products were so standardized that they really didn’t fit our solution, and so we designed and built the purge box ourselves. This stainless steel enclosure was specifically sized to house all the equipment required, including the vertical articulating arm, the Cavro ADP, and the reagents, vials and trays. We had to allow sufficient space for the robotic arm to operate – pipetting with the Cavro ADP, capping and uncapping vials and moving them to a sonic probe – and to accommodate any cables.”

“We can now perform batch processing of samples by placing them in individual vials inside the glovebox, and process an entire grid of these vials in one run. A batch of up to 56 vials can be processed, with each one taking around 20 minutes to complete. You just load the cell, close the box and purge it with nitrogen, then start the run

and walk away. Consistency is essential for the synthesis to work, and the Cavro ADP has been vital to the success of the project,” concluded Kent.

Autoimmune diseases are caused by an inappropriate immune response that results in the body attacking its own tissues and generating autoantibodies. The prevalence of these diseases is increasing worldwide, with only limited diagnostic tools available. The National Institute of Molecular Genetics (INGM), based on the IRCCS Ospedale Maggiore campus in Milan, Italy, is a non-profit research foundation that was set up to perform research into the discovery and initial development of innovative therapies and diagnostics for tumors and autoimmune diseases. As an advanced research center, INGM is creating a well-defined niche of activities in the field of human proteomics research, taking advantage of its location to establish strong connections with hospital clinics. Its diverse network of public and private collaborations with leading Italian and international institutes and biotechnology companies is playing a key role in the identification of new therapeutic targets, and the development of new diagnostic methods for neoplastic and autoimmune diseases.

INGM’s proteomic group focuses its research on the development of reliable and automation -friendly assays for screening large sets of sera for new biomarkers in autoimmune diseases. Mauro Bombaci, group leader of the protein microarray laboratory – which specializes in method development and the validation of novel candidates – described the Group’s work: “We are a multidisciplinary research center involved in the discovery of new signature profiles in autoimmune diseases. Our work involves the use of protein microarrays to perform a variety of assays – including biomarker identification, antibody specificity profiling, protein-protein interaction studies and drug target discovery – and we are currently turning our attention to the development

of a protein microarray containing poorly-characterized recombinant human proteins that are predicted to be surface-exposed or secreted.”

“We need to be able to perform a wide variety of tasks and implement new processes, from general liquid handling for a range of different purposes, to running ELISA, DELFIA® and Bio-Plex® assays. High throughput screening is also important, helping us to be competitive in the marketplace. To achieve these goals, we have invested in a Freedom EVO 150 workstation equipped with Liquid Handling (LiHa) and Robotic Manipulator (RoMa) Arms, an integrated Infinite® F200 multimode microplate reader, an ambient temperature incubator, a HydroSpeed™ washer, a Variomag® Teleshake, a heating plate and various hotels that allow us to store up to 15 microplates. We also have a HS 4800™ Pro hybridization station and an Infinite M200 microplate reader.”

Making advances in the battle against autoimmune disease

Mauro continued: “We use our Freedom EVO workstation to run fully automated DELFIA TRF assays. The DELFIA is a robust, high performance immunodetection assay that uses Eu-labelled anti-human IgG to detect antibodies in sera, offering several advantages over conventional ELISAs, such as enhanced sensitivity and a wider dynamic range. As we often use sera from patients suffering from infectious diseases, we prepare our sera dilutions prior to analysis in a sterile clean room, then use the Freedom EVO workstation to perform the assay, analyzing the samples and controls in 96-well microplates. Automating DELFIA protocols on the Freedom EVO enables us to screen large sample numbers to validate new biomarkers in autoimmune diseases.”

“Before we purchased the Freedom EVO, we used manual and semi-automatic processes to perform our assays. The system is reliable and easy to use, and allows us to process

Leading the debateMass spectrometry (MS) has long been associated with the analysis of small molecules and their metabolites as part of the drug discovery and development process. However, over the last 10 years there has been a significant increase in the use of MS in a clinical setting, driven by a number of technical innovations – expanding the range of molecules that can be detected – and the development of more user-friendly software and bioinformatics tools.

MS applications now include biomarker analysis, identifying genes, lipids, proteins and metabolites that have diagnostic potential in disease management; forensic toxicology applications, particularly in the analysis of pain management drugs and their metabolites; and lipid profile analysis to reveal alterations that occur in metabolic diseases.

To support MS customers, Tecan has developed a range of sample preparation applications and protocols on the Freedom EVO liquid handling platform. From simple sample handling, aliquoting and dilution protocols to MALDI target plate set-up and advanced sample processing such as protein crash, liquid-liquid and solid-phase extraction protocols.

Recognizing the growing importance of this technique to both Tecan and its customers, this year’s Tecan Symposium in Boston, USA, will focus on MS. Titled Mass spectrometry – the expanding role

in life sciences and diagnostics, the Symposium will feature speakers from a number of organizations using MS techniques in the clinical environment. Presentations will cover the use of MS technology in a range of areas including protease analyses as cancer biomarkers, automation of sample handling for analysis of 25-hydroxy vitamin D by LC-MSMS, and its use in assays where samples are precious or minimal, such as pediatrics and neonates.
