Recombinant Influenza A H5N1 (A/VietNam/1203/2004) HA protein(Met1-Arg342), His&Fc-tagged

• Cat.No.: HA-3216V
• Product Overview: Recombinant Influenza A Virus H5N1 Hemagglutinin (AAW80717.1)(Met 1-Arg 342), termed as HA1, was expressed in HEK293, fused with the C-terminal Fc region of Mouse IgG1 followed by a polyhistidine tag.

Specification

• Source: HEK293
• Species: H5N1
• Tag: C-His&Fc
• Protein length: Met1-Arg342
• Form: Lyophilized from sterile 100mM NaAc, 10mM NaCl, 200mM Tris, pH 7.5. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant HA1 subunit of the Influenza A virus (A/VietNam/1203/2004 (H5N1)) hemagglutinin consists of 569 amino acids and predicts a molecular mass of 64.4 kDa.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 90 % as determined by SDS-PAGE.
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted 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.
