[Comparative characteristics of the biophysical properties of influenza A, B and C proteins]

A comparative analysis of electrophoregrams of influenza A, B, and C virus proteins in polyacrylamide gel and in agarose was made. Separation of proteins was similar in three influenza C virus strains tested and differed from that of influenza A and B virus proteins. The possibility of preparative isolation of supercapsid and internal proteins of influenza C virus with preservation of their antigenic and immunogenic properties was demonstrated. Antisera to internal proteins and hemagglutinin of influenza C virus were prepared. Both antisera reacted in the double immunodiffusion test and ELISA, and antiserum to hemagglutinin also in hemagglutination inhibition test.
