Abstract
A novel purification scheme is described for obtaining two novel and useful forms of bovine glycoprotein (BGP) from bovine erythrocytes, each of which acts as an antigen in testing for the presence of the heterophile antibodies of human infectious mononucleosis. The first, or partially purified, BGP is obtained from crude BGP and contains about 10% by weight of a complex glycoplipid. It forms a single band upon gel electrophoresis at pH 7.0 under specified conditions. The second, or homogeneous, BGP is obtained by removing essentially all of the complex glycolipid. It forms substantially a single band upon gel electrophoresis at pH 7.0 under specified conditions. Both forms may be used to detect or quantify hemagglutination inhibition of a test sample (and hence to determine the presence or extent to mononucleosis infection) in a glass slide test wherein the partially purified or homogeneous BGP is carried on latex or synthetic resin beads. The homogeneous BGP is also useful in an immunoassay, preferably a radioimmunoassay, for heterophile antibodies characteristic of infectious mononucleosis.
