Abstract
A method for producing a purified polyclonal anti-HCP antibody preparation is disclosed. The method can comprise acquiring a sample comprising antibodies from an animal immunized with HCP of a host cell, separating antibodies from the sample by contacting the sample with a protein A affinity reagent to provide an antibody preparation, separating anti-HCP antibody from the antibody preparation by contacting the antibody preparation with an HCP-affinity reagent comprising HCP coupled to a substrate, and isolating the separated polyclonal anti-HCP antibody preparation.
