Product Overview
A DNA sequence encoding the N-terminal segment (Met 1-Arg 338) of the influenza hemagglutinin (Influenza A virus (A/Chicken/Hong Kong/G9/97 (H9N2)) (AAF00701.1), termed as HA1, was fused with a polyhistidine tag at the C-terminus.
Molecular Weight
The secreted recombinant HA1 subunit of influenza A H9N2 HA (Influenza A virus (A/Chicken/Hong Kong/G9/97(H9N2)) comprises 331 amino acids and has a predicted molecular mass of 37 kDa. As a result of glycosylation, it migrates as an approximately 50 kDa band in SDS-PAGE under reducing conditions.
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Purity
> 97 % as determined by SDS-PAGE
Format
Lyophilized from sterile PBS, pH 7.41. 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.
