In competitive radioimmunoassay of purified HBsAg preparations less than 1% of normal human serum antigens was found in weight equivalents. In radioimmune precipitation 125I-HBsAg was precipitated by antiserum to normal human serum proteins. The use of successive precipitation of the label with virus-specific and polyprecipitating antisera established the association of the detected antigenic determinants of the host with some portion (52%) of HBsAg structures.
