• Cat.No.: HA2-1643I
• Product Overview: Recombinant Influenza A H5N1 (A/VietNam/1203/2004)(Gly 347-Gln 531)(AAW80717.1), termed as HA2, was expressed in Human Cells, fused with the Fc region of mouse IgG1 at the N-terminus.

Specification

• Species: H5N1
• Source: Human Cells
• Tag: mFc
• Protein Length: 347-531 aa
• Form: Lyophilized from sterile 100mM NaAc, 10mM NaCl, 200mM Tris, pH 7.5.
• Molecular Mass: Recombinant mFc/HA2 is a disulfide-linked homodimeric protein. The reduced monomer consists of 422 amino acids and has a calculated molecular mass of 47.9 kDa. As a result of glycosylation, the mFc/HA2 monomer migrates as an approximately 50-55 kDa protein in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 95 % 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.
