H5N1 HA Protein Product Information
Synonym:HA1
Protein Construction:A DNA sequence encoding the N-terminal segment (Met 1-Glu 340) of the influenza A H5N1 hemagglutinin (A/Hong kong/213/2003 (H5N1)) (ABP51975.1), termed as HA1, was fused with a C-terminal polyhistidine tag, with one amino acid mutated (28 Ser / Trp).
Species:H5N1
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.
H5N1 HA Protein QC Testing
Purity:> 97 % 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 17
Molecule Mass:The secreted recombinant HA1 subunit of influenza A H5N1 HA (A/Hong kong/213/03 (H5N1)) comprises 335 amino acids and has a predicted molecular mass of 38 kDa. As a result of glycosylation, it migrates as an approximately 45-50 kDa band 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.
H5N1 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.
