H5N8 HA Protein Product Information
Synonym:Hemagglutinin, HA
Protein Construction:A DNA sequence encoding the Influenza A virus (A/turkey/Ireland/1378/1983(H5N8)) hemagglutinin (ABI85117.1) (Met1-Gln527), termed as HA, was expressed with a polyhistidine tag at the C-terminus.
Species:H5N8
Expressed Host:Baculovirus-Insect 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.
H5N8 HA Protein QC Testing
Purity:> 90 % as determined by SDS-PAGE.
Bio-Activity:1. Measured by its ability to bind with Neu5Aca2-3Galb1-4GlcNAcb-PAA-biotin (01-077) using the Octet RED System.
2. Measured by its ability to bind with Neu5Aca2-6GalNAca-PAA-biotin (01-059) using the Octet RED System.
3. Measured by its ability to agglutinate guinea pig red blood cells. HA titer is 4-16 μg/mL for 1% GRBC.
Endotoxin:<1.0 EU per μg 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 recombinant HA subunit of the Influenza A virus (A/turkey/Ireland/1378/1983(H5N8)) consists 522 amino acids and predicts a molecular mass of 59.4 kDa.
Formulation:Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 10 % glycerol, 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.
