• Cat.No.: HA-799V
• Product Overview: Recombinant extracellular domain (Met 1-Ile 528) of the influenza H4N4 hemagglutinin ((A/mallardduck/Alberta/299/1977 (H4N4)) (Q0A4G1), was fused with a polyhistidine tag at the C-terminus.

Specification

• Species: H4N4
• Source: HEK293
• Tag: His
• Protein Length: 1-528 a.a.
• Predicted N Terminal: Gln 17
• Form: Lyophilized from sterile PBS, pH 7.4, 5% ~ 8% trehalose and mannitol.
• Molecular Mass: The secreted recombinant influenza A H1N1 HA ((A/mallard duck/Alberta/299/1977(H4N4)) comprises 523 amino acids and has a predicted molecular mass of 59 kDa. As a result of glycosylation, it migrates as an approximately 65 kDa band in SDS-PAGE under reduc
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >97 % as determined by SDS-PAGE
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: Store it under sterile conditions at -20ºC~-70ºC. 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 0.25 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
