    H9N2 (Influenza A) Background

    H9N2 is a subtype of influenza A virus. H9N2 has been isolated from duck and chicken for many years, and is found in birds, pigs and other animals in Europe and Asia. Infection in humans is rare, and appears to lead to a mild disease. Six human cases of the H9 viruses have previously been reported in Hong Kong since 1999. In 1999 and 2003, an H9N2 influenza strain caused illness in three people, aged one, four and five years old, in Hong Kong. In 2007 an H9N2 influenza strain caused illness in a 9-month old baby in Hong Kong. And the recent case of influenza A/H9N2 in a 3 year old girl was reported on December 23, 2009. There are hundreds of strains of avian influenza viruses, but only four -- H5N1, H7N3, H7N7, and H9N2 -- are known to have caused human infections. In addition to H5N1, H9N2 is also considered to pose a threat to humanity.

    Studies on Molecular characterization of H9N2 influenza viruses by Guan Y and colleagues suggested that H9N2 is a possible source of H5N1. Phylogenetic and antigenic analyses of the H9N2 viruses isolated from Hong Kong markets suggest three distinct sublineages. Among the chicken H9N2 viruses, the PB1 and PB2 genes are closely related to those of the H5N1 viruses. Maryland's Daniel Perez and colleagues found that just a few mutations H9N2 could turn it into a virus that people catch and transmit easily.

    Influenza antibody and influenza antibodies are very important research tools for influenza diagnosis, influenza vaccine development, and anti-influenza virus therapy development. Monoclonal or polyclonal antibody can be raised with protein based antigen or peptide based antigen. Antibody raised with protein based antigen could have better specificity and/or binding affinity than antibody raised with peptide based antigen, but cost associated with the recombinant protein antigen is usually higher. Anti influenza virus hemagglutinin (HA) monoclonal antibody or polyclonal antibody can be used for ELISA assay, western blotting detection, Immunohistochemistry (IHC), flow cytometry, neutralization assay, hemagglutinin inhibition assay, and early diagnosis of influenza viral infection.

    Sino Biological has developed state-of-the-art monoclonal antibody development technology platforms: mouse monoclonal antibody and rabbit monoclonal antibody. Our rabbit monoclonal antibody platform is one of a kind and offers some unique advantages over mouse monoclonal antibodies, such as high affinity, low cross-reactivity with rabbit polyclonal antibodies.
