Study of the adsorption on and desorption from polystyrene-human serum albumin conjugates of rabbit anti-human serum albumin antibodies having different specificities.
An insoluble specific adsorbent for anti-human serum albumin antibodies was prepared by coupling human serum albumin (H.S.A.) to polystyrene by azo bonds. Rabbit anti-H.S.A. immune serum was passed through a column of the adsorbent. It was shown that different volumes of the immune serum were required for the saturation of the different determinant groups of H.S.A. by their corresponding antibodies. The elution of the anti-H.S.A. antibodies adsorbed on the column was achieved by passing successively through the column an acetate buffer pH 3.0 and a solution of 0.1 N HCl in 0.15 M NaCl. The antibodies were eluted in three different fractions, each of which was composed of gamma-globulins only. These three fractions contained different proportions of antibodies of different specificities.
