Host cell protein detection assays

During biotherapeutic manufacturing and production, CHO, HEK 293 and E.coli host cells produce HCP impurities which, if not removed, can induce immunogenicity in individuals or reduce the potency, stability, or effectiveness of a drug. Therefore, to meet regulatory organizations’ guidelines we have developed a range of HCP detection assays to improve your workflows.

In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
