Host Cell Protein (HCP) is a critical process impurity under strict control throughout the lifecycle of bioproducts including recombinant proteins, monoclonal antibodies, vaccines and gene therapy vectors. Residual HCP directly impacts product safety, efficacy and stability, and is a core regulatory indicator worldwide.
Derived from host cells, trace HCP residues may trigger adverse immune reactions, compromise physicochemical properties, accelerate product degradation and impair efficacy. Hence, stringent HCP limits have been established by global regulatory authorities.
Chinese Hamster Ovary (CHO) cells are the most widely used expression platforms for biomanufacturing due to high expression yield, complete post-translational modification and broad applicability. Reliable detection and control of CHO HCP residues are therefore essential for biopharma quality control. Traditional detection methods fail to meet the demands for high sensitivity, stability and high throughput, creating a major industry bottleneck. ELISA has become the gold standard for routine HCP quantification thanks to its wide linear range and outstanding accuracy.
Hyasen presents the CHO HCP ELISA Kit (One-step ELISA), a one-stop solution for full-process HCP monitoring. Optimized exclusively for CHO cell systems with mature pre-coated technology, this kit is applicable to cell culture testing, purification process development, bulk drug and final product QC across R&D, pilot and commercial production. It delivers high sensitivity and accuracy for both crude cell culture samples and highly purified drug substances. Featuring broad detection range, strong anti-interference capability and excellent reproducibility, the kit simplifies workflows, cuts labor costs and helps enterprises build standardized, efficient CHO HCP quality control systems.
Against increasingly rigorous global regulations, qualified, stable and efficient HCP testing tools are vital for quality assurance, regulatory compliance and market competitiveness. Professional testing solutions like our CHO HCP ELISA Kit will continuously empower bioprocess optimization and quality management, driving the industry toward higher standard, efficiency and quality.
