• Cat.No.: HA-1554I
• Product Overview: Recombinant H9N2 (A/Guinea fowl/Hong Kong/WF10/99) HA1 Subunit Protein(Met 1-Arg 338)(AAO46082.1) was expressed in HEK293, fused with a C-terminal polyhistidine tag.

Specification

• Species: H9N2
• Source: HEK293
• Tag: His
• Protein Length: 1-338 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Molecular Mass: The secreted recombinant influenza A H9N2 HA1 subunit (A/Guinea fowl/Hong Kong/WF10/99 (H9N2)) comprises 331 amino acids and has a predicted molecular mass of 37 kDa. As a result of glycosylation, it migrates as an approximately 55-65 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
