Event Overview:

Ion exchange separations are routinely used for quality attribute profiling of various biopharmaceutical format, be it charge variant analysis of monoclonal antibodies and recombinant proteins or determination of the capsid fill state of viral vectors for gene therapy.
This webinar presents a novel stationary phase media for ion exchange separations that delivers the highest resolution separation with lot-to-lot consistency. Application results for charge variant profiling of monoclonal antibodies and their various biosimilars, and the determination of full and empty AAV viral vector chromatographic separation hyphenated with native MS and direct mass technology mode charge detection will be described.
Key Learning Objectives:

  • Learn about a novel monodisperse ion exchange media for strong cation and anion exchange separation to accelerate your analytical development.
  • Learn about using LC–HRAM MS instruments for charge variant analysis of protein biopharmaceutics and full/empty AAV capsid ratio CQAs determination.

Who Should Attend:

For biopharmaceutical analytical staff who need reliability and resolution power when identifying and quantifying charge variants profiles of proteins in analytical development and QC environments.
