Biopharmaceutical industry using mammalian cell lines for production of a biotechnology product are running the risk of viral contamination. Eurofins BioPharma Product Testing Netherlands, fully GMP certified, offers the classic in vitro assay to detect adventitious viruses in cell lines/banks, virus seeds, raw materials and final products.

Is your cell bank free of adventitious agents?

Viral contamination is a major concern affecting batch release and product safety. During the production process, adventitious viruses could accidentally be introduced, for example, by using contaminated cell culture media or reagents. Other common sources are contamination caused by operators or other external factors.
