Certal CHO Detection Kit (100)

Biopharmaceutical teams working with Chinese Hamster Ovary expression systems use this residual host cell DNA quantification kit from QIAGEN to run a 100-reaction workflow that supports lot-release and in-process impurity testing across monoclonal antibody and recombinant protein production.

The assay quantifies process-related CHO DNA residuals, giving downstream purification scientists a quantitative readout to benchmark chromatography step clearance, validate filtration and viral inactivation steps, and assemble the impurity documentation required by guidance for biologics. Its format fits routine integration into documented sample chains for batch record release in regulated production.

By covering both high-molecular-weight host DNA carryover and shorter fragments generated during harvest and purification, the kit helps QC laboratories track impurity trends run to run and across process changes, supporting consistency in CHO-based bioproduction environments.
