摘要:
The present invention provides monoclonal antibodies that bind specifically to H5 subtype avian influenza virus hemagglutinin (HA) proteins, and can block the binding activity of at least 50% of the known monoclonal antibodies to the H5 subtype avian influenza virus hemagglutinin (HA) protein. The monoclonal antibodies can be used for the detection, diagnosis, prevention, and treatment of avian influenza viruses, especially the H5 subtype of avian influenza viruses. The present invention also provides the related hybridoma cell lines, isolated nucleic acid molecules and short peptides, as well as medical composition and medical diagnostic equipment and kit containing the monoclonal antibody.
摘要:
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.
