Analysis of Glycopeptide Glycoforms in Monoclonal Antibody Tryptic Digest using a UPLC HILIC Column

28 Jan 2015

This application note presents a UPLC HILIC/TUV/MS method for the separation of glycopeptides that is complementary to HILIC/FLR separation of N-linked glycans released from the protein. With this method, information about glycan heterogeneity and site occupancy is preserved and the same tryptic digest used for peptide mapping can be used. Since it does not require glycan release and labeling, complexity of sample preparation is reduced. This method is useful in the development and quality control of new protein-based therapies.

ACQUITY UPLC System

Waters

Waters ACQUITY UPLC - Dramatic Improvements in Speed, Sensitivity and Resolution Whether you work in methods development or quality assurance, in drug discovery and development or testing for safety in food supplies, you seek a productivity edge. With the ACQUITY UPLC® System, now you can get more information in a single, short run than you've ever seen with HPLC. Waters ACQUITY UPLC System UltraPerformance LC® (UPLC®) technology starts with unique 1.7 μm small-particle chemistries. Chromatographers no longer need to choose between speed and resolution–with UPLC you get both. Instrument Designed for Chemistry; Chemistry Designed for the Instrument The ACQUITY UPLC System has been holistically designed to match the performance needs of our innovative column chemistries with robust hardware, easy-to-use software and specialized support services. Small, pressure-tolerant particles High-pressure fluidic modules Minimized system volume Negligible carryover Reduced cycle times Fast response detectors Integrated system software and diagnostics With UPLC you have the ability to work more efficiently with higher speed, sensitivity and resolution at a much wider range of linear velocities, flow rates and backpressures to obtain superior results. The Waters ACQUITY UPLC System's high-pressure fluidics optimizes flow rates to make the most of small particle technology. The ACQUITY UPLC System's sample-handling design is designed to ensure exceptionally low carryover and reduced cycle time. And when interfaced with the Sample Organizer, it increases unattended sample capacity by ten times. High-speed detectors, both optical and mass, contribute to increased sensitivity and help manage the heightened speed and resolution requirements of UPLC. ACQUITY UPLC Systems are easily controlled, diagnosed, and monitored via a graphical system console interface. The console offers: Quick and easy access to critical instrument parameters Simple system start-up, elegant system status monitoring and predictive performance indicators to ensure maximum productivity Data management capabilities that are supported by both MassLynx™ and Empower™ software The ACQUITY UPLC System is also supported by Intelligent Device Management technology with our Connections® INSIGHT™ service, providing instrument diagnostics.

ACQUITY UPLC BEH Columns

Waters

In 2004, Waters revolutionized liquid chromatography with the introduction of the ACQUITY UPLC System. At the heart of the system was Waters second generation hybrid, the Ethylene Bridged Hybrid (BEH) particle. In 2005, BEH Technology preparative particle sizes (2.5, 3.5, 5 and 10 μm) with the introduction of XBridge between HPLC and UPLC Technology platforms. BEH Technology particles offer: Excellent peak shape and efficiency for basic analytes A rational array of chromatographic selectivity Improvements in chemical stability at mobile phase extremes, particularly at elevated pH
