[Intertypic antigenic determinants of intracellular proteins of different poliovirus serotypes].
Antibody against intracellular virus-specific proteins was produced by immunization of monkeys with extracts of cells infected with poliovirus of one of the three serotypes. Interactions of homotypic and heterotypic antibodies with labeled intracellular virus-specific proteins were studied. Immune complexes formed at this interaction were adsorbed on the surface of Staphylococcus aureus (strain Cowan I) cells, and the virus-specific proteins contained in these complexes were then analysed by polyacrylamide gel electrophoresis. The experimental results indicate the occurrence of identical (or close) antigenic determinants at least in the majority of similar intracellular proteins of polioviruses of the three serotypes.
