These proteins, termed host cell proteins (HCPs), have to be removed during product purification.
WebFeb 17, 2024 · The most common assay method for HCP detection is enzyme-linked immunosorbent assay (ELISA) which utilizes pre-raised HCP antibodies to detect HCPs in samples. As it utilizes enzymes to amplify the signal, ELISA is highly sensitive and can detect HCPs at a level of 1-3ng/mL. WebImmunoassays are the gold standard for HCP measurement in process development, in-process control, and drug substance release testing. While the principles of phase-appropriate use are laid out in USP<1132>, challenges remain, e.g., in the transition and bridging between different assay types.
