• Cat.No.: HA-1114V
• Product Overview: Recombinant Influenza A virus hemagglutinin (A/chicken/Alabama/1/1975 (H4N8)) (P19695) (Met 1-Ile528) was expressed in HEK293, fused with a polyhistidine tag at the C-terminus.

Specification

• Species: H4N8
• Source: HEK293
• Tag: His
• Protein Length: Met1-Ile52
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The secreted recombinant hemagglutinin of Influenza A virus H4N8 HA (A/chicken/Alabama/1/1975(H4N8)) comprises 523 amino acids and has a predicted molecular mass of 59 kDa. As a result of glycosylation, it migrates as an approximately 75 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: 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.
