Detection and Monitoring of Host Cell Proteins With LC-MS
When mammalian, yeast and bacterial expression systems are used for biopharmaceutical development, host cell proteins (HCPs) can contaminate the end product and pose a significant safety risk.
HCP-mass spectrometry (HCP-MS) analysis can be used to achieve greater coverage and information on the biopharmaceutical HCP profile than using an enzyme-linked immunosorbent assay (ELISA) alone.
This whitepaper explores how to track HCPs of concern through purification steps, develop robust removal strategies and increase the HCP population coverage achieved.
