• Cat.No.: HA-366V
• Product Overview: Recombinant N-terminal segment (Met 1-Glu 340) of the influenza A hemagglutinin H5N1 (A/duck/Laos/3295/2006 (H5N1)) (ABG67978.1), termed as HA1, was fused with a C-terminal polyhistidine tag.

Specification

• Species: H5N1
• Source: HEK293
• Tag: His
• Protein Length: 1-340 a.a.
• Predicted N Terminal: Asp 17
• Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
• Molecular Mass: The secreted recombinant HA1 subunit influenza A H5N1 (A/duck/Laos/3295/2006 (H5N1)) HA comprises 335 amino acids and has a predicted molecular mass of 38 kDa. As a result of glycosylation, the apparent molecular mass of the protein is approximately 50-55 kDa 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.
• 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.
