Influenza A H5N1 (A/VietNam/1203/2004) Hemagglutinin / HA Protein (His & Fc Tag)
A DNA sequence encoding the extracellular domain of hemagglutinin (Influenza A virus (A/Viet Nam/1203/2004 (H5N1)) (AAW80717.1) (Met 1-Gln 531) with cleavage site mutated (RERRRKKR→TETR,HA1+HA2,uncleaved) was fused with the C-terminal polyhistidine-tagged Fc region of mouse IgG1 at the C-terminus.
> 90 % as determined by SDS-PAGE
Lyophilized from sterile 100mM NaAc, 10mM NaCl, 200mM Tris, pH 7.5
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.
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.
