人胚胎肾细胞（HEK293）

Met 1 - Arg 342

A DNA sequence encoding the N-terminal segment (Met 1-Arg 342) of the influenza A hemagglutinin (A/American green-winged teal/California/HKWF609/2007(H5N2)) (ACF47563.1), termed as HA1, was fused with a C-terminal polyhistidine tag.

> 97 % as determined by SDS-PAGE

The secreted recombinant HA1 subunit of influenza A H5N2 HA (A/American green-winged teal/California/HKWF609/07 (H5N2)) comprises 337 amino acids and has a predicted molecular mass of 38.2 kDa. As a result of glycosylation, it migrates as an approximately 45-50 kDa band in SDS-PAGE under reducing conditions.

Hemagglutinin

Binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell. This attachment induces virion internalization of about two third of the virus particles through clathrin-dependent endocytosis and about one third through a clathrin- and caveolin-independent pathway. Plays a major role in the determination of host range restriction and virulence. Class I viral fusion protein. Responsible for penetration of the virus into the cell cytoplasm by mediating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane. Low pH in endosomes induces an irreversible conformational change in HA2, releasing the fusion hydrophobic peptide. Several trimers are required to form a competent fusion pore.

Lyophilized from sterile PBS, pH 7.4
1. 5 % trehalose and mannitol are added as protectants before lyophilization.
