Avian flu H9N2 nucleoprotein aa58-77. The amino acid sequence used as immunogen is 95% homologous to chicken and quail H5N1 and 90% homologous to swine H5N1.
An H6N1 influenza virus was isolated from a green-winged teal during the H5N1 outbreak in Hong Kong Special Administrative Region (SAR) in 1997. This virus possesses similar genes encoding internal proteins as in the human H5N1 and H9N2 influenza viruses. In 1999, influenza viruses from quail infected two humans in Hong Kong. suggesting the potential for avian influenza viruses to cross the species barrier and infect humans without prior reassortment in an intermediate host, such as the pig. The common features shared by H5N1 and H9N2 influenza viruses isolated from humans are the genes encoding the proteins of the replicating complex, the matrix protein (M) gene, the nonstructural protein (NS) gene, nucleoprotein (NP), and N1 neuraminidase (NA), This virus essentially represents the reemergence of the H5N1 influenza viruses with a different hemagglutinin (HA). Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilutions: Western Blot: 0.5-2ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
