[Molecular composition of phenotypically mixed virions formed during mixed infection with influenza viruses A and B].
Upon mixed infection of cultured cells by influenza viruses A/WSN/33 and B/Lee/40 the produced virions contain in their envelopes either hemagglutinin B/Lee/40, or hemagglutinins of both viruses, depending on their concentration ratio during infection. In the first case the population contains RNA segments and nucleoproteins (NP) of both viruses, in the second-exclusively RNA and NP of virus A/WSN/33. Results of immunoprecipitation with monoclonal antibodies to protein of virus A/WSN/33 with further analysis of immunoprecipitates by electrophoresis in polyacrylamide gels did not reveal the presence of virus ribonucleoproteins, containing NP of both viruses. The data obtained demonstrate the high of specificity of protein-protein recognition during reassembly of virion inner structures.
