title: [Monoclonal antibodies to NP protein and their use in studying influenza A viruses].
abstract: Monoclonal antibodies to NP-proteins of influenza A/sea gull/Kazakhstan/470/79 (H1N1) virus have been prepared. Each clone interacted with spatially non-overlapping antigenic sites of NP-protein. The clones differed in their capacity to inhibit the polymerase activity of different influenza A virus strains. F-81 clone was shown to interact actively with NP of human influenza A viruses, clone H12 reacted with both human and animal influenza viruses.
