Used in biopharmaceutical manufacturing to detect residual DNA from CHO (Chinese Hamster Ovary) cells in final protein therapeutics. Ensures product safety by confirming removal of host cell DNA, which could pose immunogenic or oncogenic risks if present above acceptable limits. Complies with USP <1134> guidelines for nucleic acid quantitation in biologics. Commonly applied during quality control of monoclonal antibodies, recombinant proteins, and other biologics produced in CHO cell lines. Helps meet regulatory requirements for purity and supports lot release testing.
