Characterization of biologics, especially mAbs, is a challenging task. To ensure safety, efficacy and potency of a therapeutic agent, biopharma companies must determine the heterogeneity of the structure as it progresses through cell culture, purification, and storage. Yet the presence of positively charged and negatively charged amino acids and negatively charged glycans (sialic acids) means that mAbs exist as multiple charged species. Understanding which amino acids or glycans are involved and their specific location within mAbs is of paramount importance.

Traditional ion exchange chromatography enables the separation of some charge variants, particularly those positioned on the surface of the protein. However, the better option for this task is microfluidic CE–MS (capillary electrophoresis - mass spectrometry) to analyze intact mAbs and assess the root cause of stressed mAbs. CE–MS provides a very powerful direct and generic tool for separation and identification of charge heterogeneity of mAbs.

Key Learning Objectives:

  • Understand the important role of CE–MS in biotherapeutic characterization
  • See what Zipchip is and how it works
  • Review a case study at Transcenta that uses CE–MS for charge variant analysis

Who Should Attend:

  • Scientists working in protein characterization labs for biotherapeutics
  • Analytical scientists working in biopharmaceutical labs
  • CDMO labs looking to optimize workflows and improve efficiency
