Immunoadsorbents that were potentially suitable for the fractionation of antibodies to myoglobin were prepared by coupling myoglobin to aminoethylcellulose, bromoacetylcellulose, CM-cellulose, an ethylene-maleic anhydride co-polymer and Sepharose 4B. A comparison of the properties of the preparations indicated that Sepharose-myoglobin was superior, as an immunoadsorbent, to the other conjugates. Elution of adsorbed antibodies with m-propionic acid, pH2.5, gave yields of precipitable antibody higher than those achieved with other dissociating solvents. Propionic acid eluted 60-100% of the antibody adsorbed by Sepharose-myoglobin, and 60-90% of the eluted protein was precipitable antibody.
