In biologics manufacturing, confidence in your cell banks is non-negotiable. Variability in identity, purity, or species of origin across Master, Working, and End-of-Production Cell Banks (MCB, WCB, EPCB) can lead to investigations, production delays, or even batch failures.

The Eurofins BioPharma Product Testing (BPT) network of laboratories offers comprehensive cell line characterisation services, helping ensure consistency from research through to production material. Whether you're preparing for regulatory submission, scale-up, or release, we can deliver the clear, validated data you need with cell line characterisation services that include:

• Species of Origin Confirmation: Ensuring the cell line matches procurement claims
• Purity Testing: Including detection of contaminating cell lines
• Identity Testing: Confirming genetic stability between banks and lots
• Adventitious Agent Testing: Including mycoplasma, viruses, and retroviral particles
• Karyotyping and Isoenzyme Analysis
• STR Profiling: For human and animal cell lines 

We support characterisation of a wide variety of mammalian, insect, and avian cell banks, including CHO, HEK, Vero, and others, with testing performed to GMP standards and in line with global regulatory expectations on:

• Master Cell Banks (MCB)
• Working Cell Banks (WCB)
• End-of-Production Cell Banks (EPCB)
• Research Cell Banks (RCB) 

Unexpected or unknown test results can delay timelines and threaten your supply chain. With facilities equipped to deliver fast turnaround times, full documentation, and detailed Certificates of Analysis, Eurofins BPT minimises that risk with proactive guidance, robust data, and a deep understanding of regulatory needs.
