Getting Started
Common chemicals and solvents are not included. Prior to beginning this protocol, the user will need to prepare the following solutions for
the generation of 24 samples for the SPE cleanup module:
1. 5 mL of 18.2 MΩ water
2. 9 mL of acetonitrile
3. 5 mL of 15:85 (v/v) 18.2 MΩ water/acetonitrile
4. 50 mL of 1:9:90 (v/v/v) formic acid/18.2 MΩ water/acetonitrile
Note: Volumes should be measured out individually and accurately (± 3%)
and then combined to make solutions 3 and 4 for the cleanup step.
1. The recommended glycoprotein concentration is 2 mg/mL.
A volume of 7.5 μL of glycoprotein solution is to be used in this
procedure. Glycoprotein samples of different concentration can
be accommodated by adjusting the water volume in Step 6.
Please note that this protocol is designed for a glycoprotein
quantity of 15 µg. Changes to the glycoprotein quantity will
affect the PNGase F to substrate ratio as well as the molar
excess of labeling reagent, which will potentially result in low
yield or so-called over labeling artifacts (see the tips and tricks
of Step 2 for more information).
2. Use of a control standard is highly recommended. Intact mAb
Mass Check Standard is provided. Reconstitute 1 vial
(1 mg/vial) of Intact mAb Mass Check Standard in 500 μL
of 18.2 MΩ water to create a 2 mg/mL IgG solution.
3. Prepare a buffered solution of 5% (w/v) RapiGest by dissolving
the contents of 1 vial (10 mg) of RapiGest in 200 μL of
5x GlycoWorks Rapid Buffer (found in the box with the
GlycoWorks Rapid PNGase F enzyme). Vortex to mix.
4. Add 15.3 μL of 18.2 MΩ water into a 1 mL tube.
5. Dispense 7.5 μL of the 2 mg/mL glycoprotein solution into
the provided Sample Collection Module box. Deglycosylation
Reaction: 1 ml Tubes or equivalent. Deglycosylation Reaction
Caps are included but optional.
6. Add 6 μL of buffered solution containing 5% (w/v) RapiGest SF.
Aspirate and dispense to mix.
nn Each reaction in the GlycoWorks RapiFluor-MS N-Glycan Kit is optimized for the release, labeling and extraction of N-glycans from 15 µg of glycoprotein. PNGase F and RapiFluor-MS reagent concentrations are designed for this exact quantity of sample. The GlycoWorks RapiFluor-MS N-Glycan Kit is designed for nucleophile free samples.
nn RapiGest SF is an anionic surfactant used in this enzymatic protocol to ensure that N-glycans are accessible to Rapid PNGase F, and that upon heat denaturation, glycoproteins do not precipitate out of solution. RapiGest is an enzyme-friendly reagent and can therefore be used at high concentrations alongside Rapid PNGase F.
nn Once RapiGest SF is reconstituted in the Rapid PNGase F Buffer as a 5% (w/v) solution, it should be used within a day. The 5% (w/v) solution of RapiGest SF can be stored at -80˚C for up to one month if longer term storage is needed between sample preparations.
nn This kit was designed to work in conjunction with HEPES buffer. The Rapid PNGase F Buffer is a 5x stock solution comprised of 250 mM HEPES and has been titrated with NaOH such that upon dilution to a 1x solution a pH of 7.9 is obtained.
Step 1. Rapid Deglycosylation: GlycoWorks Deglycosylation Module
Before you start: It is recommended, if using
heat blocks, to set the temperatures prior to
beginning so that solutions will be heated to 50 °C and at least 90 °C.
It may take 10 to 30 minutes for the heat blocks to equilibrate.
Buffer/Formulation Considerations: Avoid nucleophiles and SDS. The rapid deglycosylation procedure is facilitated by the RapiGest SF Surfactant and will be comprised by the presence of SDS. Likewise, rapid labeling will be compromised by the presence of high concentrations of nucleophiles. It is advised to dilute amine and/or thiol concentrations to <0.1 mM. Some samples may therefore require a buffer exchange step before enzymatic deglycosylation. Finally, other protein content in a sample (such as an albumin excipient) must be considered as contributing to the 15 µg quantity of protein that is prepared by each reaction in this kit.
To perform a buffer exchange or to prepare samples out of complex matrices (lysates/biofluids), consider the use of molecular weight cut off (MWCO) filtration, dialysis, or protein precipitation (i.e. ethanol precipitation). With these techniques, it is recommended to exchange a protein sample into a neutral sodium phosphate, citrate, or HEPES buffer. A matching formulation to the GlycoWorks Rapid Buffer would be 50 mM HEPES free acid titrated to pH 7.9 with sodium hydroxide.

Adapted rapid deglycosylation workflow
Challenging glycoprotein possessing disulfide bonds
Rapid deglycosylation method with Rapid PNGase F, Rapid Buffer, 1% RapiGest SF plus 4 mM TCEP.
It is suggested that TCEP be used rather than a thiol-based, nucleophilic reducing agent, such as DTT. TCEP can be tolerated in the final deglycosylation mixture at low concentrations without causing diminished Rapid PNGase F activity or negative effects on subsequent rapid labeling. TCEP HCl is an acidic salt, so care must be taken to neutralize a TCEP HCl solution with NaOH prior to use in this application. In addition to these conditions, extended incubation at this step, for up to one hour, can help.
Specialized, in-house adaptation
Extraordinarily challenging samples to completely deglycosylate
Rapid labeling with GlycoWorks RapiFluor-MS and subsequent GlycoWorks HILIC SPE can be matched to specialized deglycosylation techniques. It is advised to not deplete protein from samples prior to labeling. RapiFluor-MS labeling reactions should be performed at reagent concentrations of 36 mM and glycoprotein concentrations of 0.36 mg/mL. It is important to maintain the molar excess of the above conditions if glycoprotein concentration is adjusted.
7. Heat denature this mixture for 3 minutes using a heat block
such that the solution temperature reaches at least 90 °C.
nn These conditions can be achieved by heating the 1 mL tube with the customized heat block (p/n 186007985) for 3 minutes with the heat setting turned to ~8.5 to 9 or to a measured heat block surface temperature of 105–110 °C. The maximum temperature achieved during this heat denaturation can be a critical factor in this sample preparation. It is good practice to calibrate the settings of your instrument beforehand.
nn It is not necessary to cap the tube during this and subsequent incubation steps nor is it necessary to centrifuge any condensate that forms at the top of the tube prior to proceeding to the next steps.
nn Incubation can optionally be performed with a thermocycler. In which case, it is likely that 200 µL PCR tubes will be used. This protocol is adaptable to this vessel, though it will be necessary to transfer the glycan mixture to a ≥1 mL tube for dilution with ACN immediately before HILIC SPE (Step 2, 5). Alternatively, deglycosylation and labeling can be carried out at 2x concentrations such that sample transfer is not required upon ACN dilution (See Figure 6 for guidelines on using the GlycoWorks RapiFluor-MS N-Glycan Kit in this manner).
nn This can be accomplished by heating the 1 mL tube in an analog Boekel dry block heater with the heat setting turned to ~5.5 or to a measured heat block surface temperature of 57 °C.

9. Add 1.2 μL of GlycoWorks Rapid PNGase F, enzyme bringing the IgG concentration to 0.5 mg/mL. Aspirate and dispense to mix.
10. Incubate this mixture such that the solution temperature is maintained at 50 °C for 5 minutes. During this incubation, prepare the labeling reagent solution (Step 2, page 8).
11. Remove the 1 mL tube from the heat block, allowing the deglycosylation mixture to cool at room temperature for 3 minutes.
It is imperative that the glycoprotein be subjected to heat denaturation prior to the addition of PNGase F. In the heat denaturation step, ensure that the glycoprotein is subjected to a temperature of at least 90 °C. Some challenging samples may require such a high temperature and possibly even near-boiling conditions (100 °C) in order for complete deglycosylation to be achieved.

Step 2. Rapid Labeling of Glycosylamines
1. Prepare reagent solution by dissolving one (1) vial of 23 mg of
the GlycoWorks RapiFluor-MS Reagent Powder in 335 μL of the
provided GlycoWorks Reagent Solvent Anhydrous DMF. Aspirate
and dispense the solution 5–10 times to ensure the reagent is
dissolved. Alternatively, cap and briefly vortex the contents of
the reagent vial.
2. Add 12 μL of the RapiFluor-MS Reagent Solution to the
deglycosylation mixture contained in the 1 mL tube.
3. Aspirate and dispense the reagent solution 5 times to
ensure mixing.
4. Allow the labeling reaction to proceed at room temperature.
5. After 5 minutes, dilute the reaction with 358 μL of
ACN in preparation for HILIC SPE.
nn RapiFluor-MS is purified as a 1:1 complex with NHS. The formula weight for the reagent as provided is 542.41 g/mol.
nn RapiFluor-MS is a highly reactive, primary/secondary amine labeling reagent. It hydrolyzes in water with a half life on the order of 10–100 seconds (see Figure 4). It is, therefore, important that the reagent be dissolved in the provided anhydrous DMF, a non-nucleophilic, polar aprotic solvent. Reagent solution can be used across the span of a day if care has been taken to limit exposing the solution to atmospheric moisture. The GlycoWorks RapiFluor-MS N-Glycan Kit is segmented into 24 reaction sets so that fresh reagent can be used whenever possible.
nn Glycans are released from glycoproteins as glycosylamines, an important fact for an analyst to consider when using this labeling chemistry.
nn The concentrations of reagent and DMF solvent specified in this protocol have been optimized to ensure high yield of glycosylamine labeling. It is not recommended to make adjustments to these values without considering the yield and/or selectivity of the labeling. It is suggested to maintain a ratio of the RapiFluor-MS reagent weight concentration to protein weight concentration of ~50, so long as labeling reactions are performed on deglycosylation mixtures that have not been depleted of protein matter. DMF is present as a co-solvent in this reaction at a concentration of ~30% to ensure that RapiFluor-MS remains soluble throughout the labeling step.
nn RapiFluor-MS is an NHS-carbamate reagent. Unlike NHS-ester reagents, it hydrolyzes over time to generate carbon dioxide and a corresponding amine. This makes RapiFluor-MS labeling a self-quenching reaction. If the reaction is allowed to proceed at room temperature for a minimum of 5 minutes, a quenching step need not be performed.

Step 3. HILIC SPE Clean-Up of Labeled Glycosylamines
1. Set up a GlycoWorks HILIC µElution Plate on a vacuum manifold
outfitted with a set of 3 shims (See Table 2) and the waste tray
included in the Sample Collection Module box.
Waters has developed short, 2-minute videos for the proper use of Vacuum Manifold and Positive Pressure Processor. To watch the videos visit www.waters.com/manifolds.
2. Condition wells to be used on the μElution plate with 200 μL
of 18.2 MΩ water.
3. Equilibrate wells with 200 μL of 15:85 water/acetonitrile.
4. Load the acetonitrile diluted samples in their entirety ~400 µL.
5. Wash the well with two (2) 600 μL volumes of 1:9:90 (v/v/v)
formic acid/water/acetonitrile.
6. Replace the waste tray with a 96-well collection plate fitted
with the Labeling Reaction: 600 µL Tubes included in the
GlycoWorks Sample Collection Module box.
7. Elute glycans with three (3) 30 μL volumes of GlycoWorks SPE
Elution Buffer (200 mM ammonium acetate in 5% acetonitrile).
nn The tapered bottom inserts are provided in an 8-strip format. Separate tubes as needed for your workflow and throughput.
nn To improve uniformity of flow across different wells- one can condition 2x with water.
nn This elution buffer has been developed to deliver optimal, unbiased recovery of both small neutral glycans as well as high molecular weight, heavily sialylated glycans.
Step 4. Preparing Labeled Glycans for HILIC-FLR with an ACQUITY UPLC BEH Glycan Column
1. Dilute the 90 μL eluate with 310 µL of the GlycoWorks Sample
Diluent-DMF/ACN included in the kit prior to HILIC chromatography.
Aspirate and dispense 5x to ensure complete mixing.
nn Sample is stable at 4 °C for at least 3 days. If sitting for more than a day, before injection vortex to ensure proper mixing to minimize solvent effects if any condensation occurred. For long term storage, freeze at -80 °C.
2. Cap the tapered bottom insert using the provided pre-slit,
strip-format Labeling Reaction Caps included in the
GlycoWorks Sample Collection Module box.
nn Sample can be prepared for analysis from the SPE eluate in multiple ways. It is suggested to perform direct analysis of DMF/ACN diluted eluate. DMF is used as a co-solvent in the sample diluent to ensure miscibility and to minimize loss of sample due to precipitation. DMF/ACN dilution as described in this step allows injection volumes to be as large as 30 µL when a 2.1 mm I.D. column is used. Alternatively, the SPE eluate can be dried by centrifugal vacuum evaporation, reconstituted in water, and injected at a volume of ≤1 μL when a 2.1 mm I.D. column is used. If the above recommendations are followed, the analyst will not encounter solvent effects, such as peak broadening and peak splitting.
nn The cap mats are provided in an 8-strip format to match to the 8-strip format of the 600 µL inserts. Cut smaller lengths of the 8-strip mat as needed for your experiments.
nn GlycoWorks SPE can also be accomplished using a positive pressure manifold (PPM) outfitted with a PPM Spacer (See Table 2).
nn General Guidelines for Vacuum Manifold: A vacuum setting of 2.5–4 in Hg is optimal for all steps in the SPE process. To pull higher vacuum on isolated wells, one can cover un-used wells.
nn General Guidelines for Positive Pressure Manifold: For loading, washing, and elution, approximately 3 psi is appropriate. For conditioning, 10–20 psi can be used.
nn For low sensitivity mass spectrometers: The GlycoWorks RapiFluor-MS N-Glycan Kit was designed to provide a sample for direct LC-MS analysis using a mass spectrometer built with StepWave™ Technology. These instruments, such as an ACQUITY® QDa®, Xevo® G2-XS QTof, and SYNAPT® G2-Si HDMS, exhibit the levels of sensitivity needed to facilitate glycan LC-MS. For lower sensitivity mass spectrometers, it is suggested to dry the obtained 90 µL SPE eluate and to reconstitute the sample sequentially with 4.5 µL of water, 5 µL of DMF, and finally 10.5 µL of ACN. This highly concentrated sample can then be injected in its entirety to increase MS signal as needed.

Step 5. Recommended Analytical Approach for GlycoWorks RapiFluor-MS-labeled Glycan Analysis
Before You Get Started: Glycan BEH Amide Column Equilibration
When the column is first received, flush in 60% acetonitrile: 40% aqueous (or initial starting conditions) for 50 column volumes.
Equilibrate with 20 column volumes of initial mobile phase conditions before making first injection. Equilibrate with 8–10 column volumes
between injections. Failure to appropriately equilibrate the column could result in drifting retention times. Please refer to the ACQUITY
UPLC® Glycan BEH Amide Column Care and Use (p/n 720003042EN) on www.waters.com for proper use and storage of column.

Mass Spectrometry Analysis Considerations
Because the RapiFluor-MS label has high proton affinity,
derivatized glycans preferentially adopt high c harge
states during positive ion mode electrospray ionization.
T he predominant charge state for a small neutral glycan
is [M+2H]2+, although it increases to [M+3H]3+ for larger
molecular weight glycans. MS source conditions may require
optimization to achieve desired signal, limit in-source
fragmentation, and to minimize adduct formation.
