HAProtein Product Information
Synonym:HA1
Protein Construction:A DNA sequence encoding the Influenza A virus (A/Pigeon/Shanghai/S1069/2013(A/H7N9)) hemagglutinin (Met1-Gly338), termed as HA1, was expressed with a C-terminal polyhistidine tag.
Species:H7N9
Expressed Host:Human Cells
Form & Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
HAProtein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Asp 19
Molecule Mass:The recombinant HA1 subunit of Influenza A virus (A/Pigeon/Shanghai/S1069/2013(A/H7N9)) hemagglutinin comprises 331 amino acids and has a predicted molecular mass of 36.2 kDa. The apparent molecular mass of the protein is approximately 38-47 kDa in SDS-PAGE under reducing conditions.
Formulation:Lyophilized from sterile PBS, pH 7.4.
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
