Specification

• Species: H5N2
• Source: HEK293
• Tag: His
• Protein Length: 1-355 a.a.
• Predicted N Terminal: Asp 29
• Form: Lyophilized from sterile PBS, pH 7.4, 5% ~ 8% trehalose and mannitol.
• Molecular Mass: The secreted recombinant HA1 subunit of influenza A H5N1 HA (A/ostrich/SouthAfrica/AI1091/2006 (H5N2)) comprises 338 amino acids and has a predicted molecular mass of 38.2 kDa. As a result of glycosylation, it migrates as an approximately 50 kDa band in S
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >95 % 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.
