|Effect on Host:
Monoclonal antibody 1D8 (ATCC VR-1642) reacts specifically with influenza A virus H9 hemagglutinin by ELISA against recombinant proteins. It does not cross react with other HA types evaluated to date (H1, H2, H3, H5, H7). 1D8 is useful for western blotting and ELISA applications. Its use for immunofluorescence and ability to neutralize virus have not yet been investigated.
