H1N1 HA Protein Product Information
Synonym:HA
Protein Construction:A DNA sequence encoding the extracellular domain of Influenza A virus (A/California/04/2009 (H1N1)) hemagglutinin (ACP41105.1) (Met 1-Gln 529) with cleavage site mutated (IQS→RQRRRRK, HA1+HA2, partially cleaved) was expressed, with a C-terminal polyhistidine tag.
Species:H1N1
Expressed Host:Human Cells
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.
H1N1 HA Protein QC Testing
Purity:> 92 % 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 18
Molecule Mass:The secreted recombinant Influenza A virus (A/California/04/2009 (H1N1)) HA (mutated) comprises 527 amino acids and predicts a molecular mass of 60 kDa. As a result of glycosylation and proteolysis, the apparent molecular mass of the hemagglutinin is apparoximately 25-30, 50-55 and 80-85 kDa in SDS-PAGE under reducing conditions, corresponding to the HA2, HA1 subunit and the full length HA respectively.
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.
H1N1 HA Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
