In virus classification influenza viruses are RNA viruses that make up three of the five genera of the family Orthomyxoviridae. This virus is divided into three main types (A, B and C). Influenza A virus is capable of rapid genetic change in mammals. In humans, the need to escape preexisting immunity exerts positive selection pressure on changes in amino acids comprising the antigenic sites of the surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). There are several subtypes, labeled according to an H number (for the type of hemagglutinin) and an N number (for the type of neuraminidase).
Sino Biological Inc offer Recombinant Hemagglutinin Protein from the A/Texas/05/2009 (H1N1) for research aim.
