  • Broad-spectrum monoclonal antibody recognizing HA1 domain of hemagglutinin of influenza virus
    Patent number: 9650434
    Abstract: The invention relates to antibodies recognizing epitopes on HA1 domain of hemagglutinin (HA) protein of influenza virus, cell lines for producing the antibodies, and uses thereof. The antibodies according to the invention can specifically bind to HA1 domain of different HA subtypes and specifically bind to HA1 domain of hemagglutinin (HA) protein of H1 subtype (including seasonal H1N1 and 2009 pandemic H1N1) and H5 subtype of influenza viruses. Therefore, the invention also relates to vaccines or pharmaceutical compositions for preventing and/or treating infection of H1 subtype and H5 subtype influenza virus and/or a disease caused by the infection (e.g. influenza), comprising the antibodies according to the invention.
