Specification

• Source: HEK293
• Species: H4N6
• Tag: His
• 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 H4N6 HA (A/mallard/Ohio/657/2002 (H4N6)) comprises 523 amino acids and has a predicted molecular mass of 58.8 kDa. As a result of glycosylation, the apparent molecular mass of the protein is approximately 65-75 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.
• 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.
