Recombinant H5N1 (A/Anhui/1/2005) HA Protein

• Cat.No.: HA-276V
• Product Overview: Recombinant the N-terminal segment (Met 1-Pro 337) of Influenza A virus H5N1 hemagglutinin (A/Anhui/1/2005 (H5N1)) (ABD 28180.1), termed as HA1, was expressed.

Specification

• Source: HEK293
• Species: H5N1
• Predicted N Terminal: Asp 17
• Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
• Molecular Mass: The recombinant HA1 subunit of influenza A virus H5N1 hemagglutinin (A/Anhui/1/2005 (H5N1)) comprises 321 amino acids with the predicted molecular mass of 36 kDa. As a result of glycosylation, it migrates as an approximately 50 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >94 % 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.
