Recombinant Influenza A virus H7N9 NA, His-tagged

Cat.No.: H7N9-18I
Product Overview: A DNA sequence encoding the Influenza A virus (A/Shanghai/1/2013(H7N9)) neuraminidase (His36-Leu465) was expressed with an N-terminal polyhistidine tag.
Description: This new H7N9 virus is an avian (bird) influenza (flu) virus. Influenza (flu) is a respiratory infection in mammals and birds. The virus is divided into three main types (Influenza A, Influenza B, and Influenza C), which are distinguished by differences in two major internal proteins (hemagglutinin (HA) and neuraminidase (NA)). The influenza viral neuraminidase (NA) protein is a tetramer with an enzyme active site on the head of each monomer. Subtypes are further divided into strains; each genetically distinct virus isolate is usually considered to be a separate strain. NA protein is a second major surface antigen of the virion. Neuraminidase (NA) cleaves terminal sialic acid from glycoproteins or glycolipids. Thus, it functions to free virus particles from host cell receptors, to permit progeny virions to escape from the cell in which they arose, and so facilitate virus spread.
