[Isolation of the internal proteins of the influenza virus by preparative polyacrylamide gel electrophoresis for obtaining monospecific antisera].

The principal possibility of isolation of internal proteins (M and NP) of influenza type A (H1N1 and H3N2) and B viruses by SDS-PAG preparative electrophoresis and preparation of monospecific antisera to these proteins was demonstrated. The resulting preparations may be used for testing the biological objects by enzymeimmunoassay.
