Impact of Scalable Freeze/Thaw Cycling on Protein Stability and Structure

recorded webinar

Freezing and thawing of biologics is often overlooked in the biomanufacturing workflow. Considering its impact on critical quality attributes in post downstream processing, it should be treated as a unit operation of its own. And like most unit operations, freeze/thaw has its own set of process challenges focused on product stability, integrity, and scalability.

For commercial scale freeze/thaw of bulk active pharmaceutical ingredients (API), a model protein study can help to better understand and alleviate risks.

This webinar will:

  • Review key requirements and considerations for freezing bulk drug substances or APIs
  • Evaluate a model protein stability study to determine optimal freeze/thaw solutions
  • Highlight the challenges associated with freeze/thaw of bulk API, specifically proteins and monoclonal antibodies
  • Share key characteristics of a scalable freeze/thaw commercial unit operation
  • Demonstrate the importance of the right formulation, container, and freeze method on product quality attributes through a model protein study
