Recombinant H8N4 (A/pintail duck/Alberta/114/1979) HA protein, His-tagged

• Cat.No.: HA-3231V
• Product Overview: Recombinant H8N4 (A/pintail duck/Alberta/114/1979) HA protein(Met 1-Arg 344)(ABB87729.1) was expressed in HEK293, fused with a C-terminal polyhistidine tag.

Specification

• Species: H8N4
• Source: HEK293
• Tag: His
• Protein Length: 1-344 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Molecular Mass: The secreted recombinant influenza A H8N4 HA1 subunit (A/pintail duck/Alberta/114/1979 (H8N4)) comprises 338 amino acids and has a predicted molecular mass of 38.6 kDa. As a result of glycosylation, it migrates as an approximately 50-60 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.
