• Cat.No.: HA-283V
• Product Overview: Recombinant H1N1 (A/California/04/2009) HA protein(ACP41105.1)(Met 1-Gln 529) (Native, HA1+HA2, uncleaved) was expressed in HEK293 with a C-terminal polyhistidine tag.

Specification

• Species: H1N1
• Source: HEK293
• Tag: His
• Protein Length: 1-529 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Molecular Mass: The secreted recombinant hemagglutinin of Influenza A virus (A/California/04/2009 (H1N1)) comprises 523 amino acids with the predicted molecular mass of 59 kDa. As a result of glycosylation, it migrates as an approximately 75-80 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 90 % 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.
