Residual DNA Testing

Residual DNA or Host Cell DNA can be a contaminant present in biologicals that are co-purified with drug substances. These types of DNA can have negative effect therefore manufacturers of biologicals must ensure that the final products derived from continuous mammalian cell lines contain acceptable levels of host cell DNA.

Residual DNA testing ensures your drug’s final dosage form meets the requirements as established by the World Health Organization (WHO), the European Pharmacopeia, the US Food and Drug Administration (FDA), and other regulatory agencies. Therefore, we recommend testing for traces of DNA during:
