Applying best in class size exclusion chromatography technologies to the analysis of antibodies and glycoproteins


Learn about the uSA_Logo_NoOrb_R_RGBse of versatile analytical techniques including oligosaccharide analysis, monoclonal antibody aggregate quantification and application of SEC-MS towards high-throughput intact mass glycoprofiling.

High-performance liquid chromatography is a fundamental method for research and quality control of biopharmaceutical products.

This webinar will focus on the versatile use of size exclusion chromatography in analyzing antibodies and glycoproteins. We will cover tips and tricks with regards to buffer choice for size exclusion chromatography coupled to mass spectrometry, advantages of fluorescence detection in hydrophobic interaction chromatography, as well as the use of buffer additives in size exclusion chromatography of monoclonal antibodies.

The second part of this webinar will show the application of SEC-MS towards high-throughput intact mass glycoprofiling of biotherapeutic antibodies and Fc-fusion proteins.

What will you learn?

  • Tips and tricks with regards to buffer choice for size exclusion chromatography coupled to mass spectrometry and how SEC-MS can be used for rapid glycoprofiling of therapeutic proteins and antibodies.

Who may this interest?

  • Bench biochemists and managers interested in new tips and tricks for size exclusion chromatography
  • Analysts and managers interested in improving bioseparations
  • Pharmaceutical researchers studying glycosylation of biotherapeutics.
