Host Cell Protein Analysis

Identify and quantify host cell protein contaminants

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. Purification of the drug from these HCP contaminants can be challenging, with low-level contamination remaining after purification. Host cell proteins (HCPs) accompanied with recombinant biotherapeutics can significantly affect drug efficacy and cause immunogenicity. Detection and quantification of residual HCPs as potential process-related impurities is critical for biopharmaceutical companies in accordance with regulatory agency guidelines (ICH Q6B).

Orbitrap-based MS analysis of HCP contaminants using the Thermo Scientific Orbitrap Fusion Lumos Tribrid Mass Spectrometer offers a comprehensive approach to identifying and quantifying these protein contaminants.
