CHO Residual DNA Quantitation

Precise control of residual host cell DNA is a critical requirement in biopharmaceutical manufacturing, where even trace contamination can impact product safety and regulatory compliance. Advanced real-time PCR technology now enables highly sensitive, CHO-specific DNA detection down to sub-picogram levels, supporting confident monitoring across both in-process and final product samples. Optimized sample preparation ensures consistent recovery from complex matrices, including protein-rich or high-salt environments, while maintaining reproducibility and throughput efficiency. With integrated workflows that combine extraction, assay setup, and analysis in a streamlined process, results can be achieved in under five hours. High specificity eliminates cross-reactivity with unrelated DNA, and robust performance remains consistent across fragmented and intact DNA samples.
