title: [Comparative study of the electrophoretic mobility of the polypeptides from avian influenza viruses type A].
abstract: A comparative study of the electrophoretic mobility of polypeptides of avian influenza viruses was carried out; molecular weights of polypeptides and their percent content were determined. Strains isolated from one host and possessing different hemagglutinin serotypes were found to have different electrophoregrams due to differences in the position of the light or heavy chain of hemagglutinin. Hemagglutinins (Hav7, Heq2, H3) and (Hav1, Heq1) in virions isolated from different hosts had similar electrophoretic mobilities of the heavy and particulary light chain. No significant variations in the molecular weights of NP and M proteins of all the viruses under study were found. No identity in the electrophoretic mobility and content of P1--P3 proteins in different strains of avian influenza virus was found.
