Specification

• Source: HEK293
• Species: Influenza A H13N8 (A/black-headed gull/Netherlands/1/00)
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Molecular Mass: The secreted recombinant HA1 subunit influenza A H13N8 HA (A/black-headed gull/Netherlands/1/00 (H13N8)) comprises 335 amino acids and has a predicted molecular mass of 37.4 kDa. As a result of glycosylation, the apparent molecular mass of the protein is approximately 55 kDa in SDS-PAGE under reducing conditions.
• Protein length: Met1-Arg342
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. 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 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
