Host Cell Protein (HCP) Contamination Detection Service for Antibody Formulation
Pinpoint Impurities, Perfect Your Antibody
Host cell proteins (HCPs), produced during recombinant expression in systems such as CHO or HEK293, can remain in final antibody products despite multi-step purification. Even trace amounts may affect safety, efficacy, and stability. Are you facing immunogenicity risks, inconsistent batch quality, or regulatory concerns caused by residual host cell proteins in your antibody formulation? HCP contamination detection service at Creative Biolabs helps you mitigate contamination risks and maintain product consistency through optimized immunoassay platforms, orthogonal LC-MS methods, and matrix-specific validation.
We deliver an integrated contamination detection solution, giving you both the quantitative totals and the qualitative identities of HCPs impacting your product. This dual insight enables informed decision-making on clearance strategies, process refinement, and long-term quality control, ensuring consistent antibody formulations.
What We Can Offer:
- Quantitative HCP analysis with detection limits in the low ng/mg range.
- Orthogonal LC-MS profiling for identification and relative abundance of individual HCP species.
- Coverage analysis for ELISA antibodies to ensure detection relevance to the host system.
- Comparative lot analysis to support process validation, tech transfer, and troubleshooting.
- Detailed interpretive reports with compliance-ready documentation.
