Product Overview
A DNA sequence encoding the Influenza A virus (A/Shanghai/1/2013(H7N9)) hemagglutinin (Met1-Gly338), termed as HA1, was expressed with a C-terminal polyhistidine tag.
Molecular Weight
The recombinant HA1 subnunit of Influenza A virus (A/Shanghai/1/2013(H7N9)) hemagglutinin comprises 331 amino acids and has a predicted molecular mass of 36.3 kDa. The apparent molecular mass of the protein is approximately 42 kDa in SDS-PAGE under reducing conditions.
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Purity
> 95 % as determined by SDS-PAGE
Format
Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 10% glycerol, 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.
