Security Of Supply For Critical Reagents Used In HCP Analysis

Source: Cytiva

The most common method scientists use to monitor host cell protein (HCP) levels in biologics is the enzyme-linked immunosorbent assay (ELISA). For the reagent, security of supply is a regulatory requirement ⁠— it’s a factor that’s critical to consistently monitoring HCP during biologic production. In this webinar, we discuss why security of supply is important, the consequences of not having it, and how to mitigate this risk.

Topics covered

  • Why security of supply is critical to your HCP plans
  • Consequences of not securing supply upfront
  • How to mitigate risk by securing supply distribution
  • Differences between antisera batch and ELISA lot
