E.coli HCP ELISA kit

This kit was developed using broadly reactive polyclonal antibodies to the hundreds of different HCPs and is intended for use in determining the presence of E.coli host cell protein contamination in products manufactured by recombinant expression. Our assay validation has determined that the LOD for this kit is ~0.2ng/mL.
