Event Overview:
With multiple, complex chromatographic purification, buffer exchange, and viral inactivation steps, downstream processing of monoclonal antibodies (mAbs) remains the major bottleneck in biopharmaceutical production. This webinar will discuss critical evaluation and selection considerations for proper materials and reagents during process development and how these considerations are crucial in developing and optimizing a robust purification process. The webinar will also examine how a novel affinity chromatography resin, combined with selective additives, offers enhanced purification and improved removal of impurities, such as host cell proteins, DNA, and viruses, providing a model for the kinds of steps that can be taken to lead to improvements in overall mAbs manufacturing process efficiencies.

Key Learning Objectives:

  • Provide insights into key aspects of efficient viral inactivation and purification in the context of an overall virus safety assessment and control strategy purification
  • Review how proteins-based affinity ligands can be better engineered and provide increased purification of FC-fusion proteins
  • Show how the combination of a novel Protein A affinity chromatography resin with select additives further enhances impurity removal.

Who Should Attend:

Biopharma production professionals —downstream process engineer, downstream scientist, manager downstream process development, production and operations manager, research scientist
