[Radioimmunological analysis of the antigenic variability of influenza virus nucleoprotein].
Influenza A virus ability to bind anti-NP monoclonal antibodies to two viral strains has been studied by radioimmunoassay on polyethylene film with the subsequent autoradiographic registration of results. Monoclonal antibodies were obtained to the viral strains differing in antigenic formula of outer glycoproteids and isolated at different time. The studied influenza viruses were divided into seven groups due to their ability to bind monoclonal antibodies. The absence of correlation between the antigenic properties of nucleoprotein and glycoproteids has been registered. Variability of some antigenic sites has been analyzed. The human epidemic strains of influenza virus are different in ability to bind monoclonal antibodies from the viral strains that are connected with animals in nature or laboratory practice.
