Target Information

Host Cell Proteins (HCPs) are process-related impurities derived from host cell expression systems that may be present in trace amounts in final drug substances.
HCP Antibodies are used to detect impurities in biologically based therapeutics.
2D electrophoresis western blot analysis provides more complete insight into the immunocoverage of protein components of the host cell lysate, beyond what can be detected by 1D electrophoresis.
