Residual DNA Testing

Biopharmaceutical products, such as therapeutic proteins and vaccines, are produced by fermentation using either bacterial or eukaryotic cells. The cells used to produce biopharmaceuticals can be sources of a range of complex, heterogeneous, and potentially unsafe impurities, and host cell DNA is among these. The residual host cell DNA may result in tumors or adverse reactions. Besides, cells used to produce biopharmaceuticals may possibly carry viruses or harbor harmful nucleic acid, and the residual DNA in a given biopharmaceutical product may be infectious.
