CHO cells are widely used expression hosts for recombinant proteins and are utilized for the generation of monoclonal antibodies. The CHO Host Cell Proteins (HCP) kit is designed to measure contaminants originating from the CHO cells used to manufacture therapeutic antibodies. This kit can be utilized to quantify CHO HCP proteins at various stages, from routine bioprocess operations to crude harvest materials to final products. Our simple procedure and robust assay offer increased throughput compared to ELISA.

Formats:

• Our 100 assay point kit allows you to run 100 wells in 96-well format, using a 50 µL reaction volume (5 µL of sample).
• Our 500 assay point kit allows you to run 500 wells in 96-well or 384-well format, using a 50 µL reaction volume (5 µL of sample).
• Our 5,000 assay point kit allows you to run 5,000 wells in 96-well or 384-well format, using a 50 µL reaction volume (5 µL of sample).

AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. 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.
