Product Overview
A DNA sequence encoding the Influenza A virus (A/Shanghai/1/2013(H7N9)) hemagglutinin (Met1-Val524) (cleavage between Arg339 and Gly440, HA1+HA2) was expressed with a C-terminal polyhistidine tag.
Molecular Weight
The recombinant hemagglutinin of Influenza A virus (A/Shanghai/1/2013 (H7N9)) comprises 517 amino acids and has a predicted molecular mass of 57.7 kDa. The apparent molecular mass of the protein is approximately 67, 43 and 30 kDa in SDS-PAGE under reducing conditions.
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Purity
(14.6+44.8+39.6) % as determined by SDS-PAGE
Format
Lyophilized from sterile PBS, pH 7.4.1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Storage
Samples are stable for up to twelve months from date of receipt at -70°CStore it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
