Influenza A Virus H5N1 (A/Cambodia/S1211394/2008) Hemagglutinin / HA Protein (His Tag)

HA

Catalog Number P40026-V08H
Organism Species H5N1
Host Human Cells
Synonyms HA
Molecular Weight The secreted recombinant HA1 subunit of influenza A H5N1 HA (A/Cambodia/S1211394/2008(H5N1)) comprises 526 amino acids and has a predicted molecular mass of 60 kDa. As a result of glycosylation, it migrates as an approximately 83 kDa band in SDS-PAGE under reducing conditions.
predicted N Asp 17
SDS-PAGE
Purity > 95 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the N-terminal segment (Met 1-Gly 341) of the influenza hemagglutinin (A/Cambodia/S1211394/2008 (H5N1)) (ADM95445.1), termed as HA, was fused with a polyhistidine tag at the C-terminus.
Bio-activity Measured by its ability to agglutinate guinea pig red blood cells.
HA titer is 4-16 μg/mL for 1% GRBC.
Research Area Microbiology |Pathogenic microorganism |viruses |animal virus |viral illness |Viral tract respiratory illness |
Formulation Lyophilized from sterile PBS-2, pH 7.4, 10% gly
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
