Biologics Testing

A Comprehensive Biologics Testing Service Supports Drug Developers and Commercial Biologics Manufacturers From Discovery Through Commercial Manufacturing

When producing biologic products from mammalian cell lines and viruses, there is an inherent risk of introducing microbial- and viral-based contaminants. Regulatory bodies such as the European Medicines Agency (EMA), Medicine and Healthcare Products Regulatory Agency (MHRA) and Food & Drug Administration (FDA) ensure the safety and test of new protein-based biologics, biosimilars, viral vector gene therapy and viral vaccines. These guidelines are determined by the nature of the cell line or virus and the intended use of the product – and compliance is demonstrated through biologics testing.

Sartorius provides comprehensive biologics testing solutions for all stages of drug development, from discovery to commercial release.

Our global cGMP-compliant testing facilities are FDA- and MHRA-approved for biologics testing of viral vector gene therapies, cell therapies, viral vaccines, new biologics and biosimilars.

Outsourcing biologics testing to Sartorius expedites analytical development and lot release timelines with immediate access to highly specialized ready-to-use or custom assays, platform methods and complex analytical equipment – ultimately expanding your quality control workbench.
