About this webinar

Cell line characterization is key to ensuring the safety of biologics. Even with recent innovations in adventitious agent detection for cell banks, transmission electron microscopy (TEM) remains a cornerstone of these activities.

This webinar will explore the capabilities of TEM for cell line characterization to understand why regulators still consider this assay to be a central component of the testing package.

The featured speakers will also examine how TEM contributes to a comprehensive safety profile when combined with complementary assays tailored to specific cell types, highlighting its strengths in detecting diverse adventitious agents and offering strategies to align with current regulatory expectations.

Register for this webinar to learn how TEM supports comprehensive cell line characterization strategies aligned with current regulatory expectations.

Who should attend

This webinar will appeal to professionals in:
  • Process Development
  • CMC Managers
  • Quality Assurance
  • Regulatory Affairs
  • Quality Control Manager
