The uses of monoclonal antibodies as enzyme conjugates and as immunoaffinity reagents require their purification from the crude ascites fluid. This unit provides protocols for purification using protein A-Sepharose chromatography and affinity chromatography, which are superior to ammonium sulfate precipitation, gel filtration, or ion-exchange chromatography for the preparation of contaminant-free antibody.
