Event Overview:
Use of cation-exchange (CEX) chromatography for accurate quantitation of mAb charge variants with optical detection is a well-accepted and used technology. This technical webcast details the development and use of CEX with mass spectrometry (MS) volatile eluents to provide high quality MS data of well separated native mAb species. Learn tips and tricks on implementing this technology to address the characterization and monitoring of charge variants of mAbs from research to product commercialization. Topics discussed in this webcast will include:

  • Principles and practice using cation-exchange chromatography 

  • Capillary electrophoresis vs. ion exchange (IEX)-based separations

  • Development of a volatile IEX eluent for online MS characterization
  • How the technology can demonstrate accurate quantitation, cleaner spectra with less adduct noise or super charging, MS of native proteins, and reduced ion suppression

  • Method robustness and reproducibility

  • Simplified data interpretation

  • Time savings

Key Learning Objectives:

  • Learn how online liquid chromatography (LC)–MS analysis provides cleaner spectra and simplified data interpretation 

  • Understand eluent preparation, use, and storage 

  • Review benefits and optimization of MS detector

  • Learn how to interpret MS data of mAb charge variants
