Host cell protein assays
WebHost-cell proteins are essential but non-desired proteins produced by bioproduction host cells (e.g., CHO cells, E. coli, yeast) used to produce monoclonal antibodies, recombinant proteins, and vaccines. WebAug 28, 2024 · What is a host cell protein assay? August 28, 2024 by Alexander Johnson. Host cell proteins (HCPs) are low-level, process-related protein impurities in drug products derived from the host organism during biotherapeutic manufacturing. During expression of a recombinant protein drug, host cell systems can express many endogenous proteins.
