Recombinant Human VWF, His tagged

• Cat.No.: VWF-894H
• Product Overview: Recombinant Human VWF pro form (NP_000543.2) (Met 1-Lys 2813), fused with a C-terminal polyhistidine tag, was produced in CHO Cells.

Specification

• Species: Human
• Source: CHO
• Tag: His
• Protein Length: Met 1-Lys 2813
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The secreted recombinant human vWF consists of 2802 amino acids after removal of the signal peptide and has a predicted molecular mass of 308 kDa. Purified rhvWf exists as both the pro form with the pro peptide (307 kDa) and the mature form (226 kDa), which migrates as doublets with apparent molecular mass of 260 and 350 kDa respectively in SDS-PAGE under reducing conditions due to glycosylation.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 75 % 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℃ before opening to recover the entire contents.
