Human Coagulation Factor IX / FIX / F9 Protein (His Tag)

Sino Biological


  • Tag: C-His
  • Purity: ≥ 95 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.
  • Source: HEK293 Cells
  • Species: Human
  • Storage: Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
  • Activity: Measured by its ability to cleave the peptide substrate, Z-D-Arg-Gly-Arg-pNA. The specific activity is >20pmols/min/ug.
  • Molecule: F9
  • Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
  • Lead Time: 1-3 days
  • Formulation: Lyophilized from sterile PBS, pH 7.4
  • Molecular Mass: The secreted recombinant human F9 (pro form) consists of 444 amino acids and predictes a molecular mass of 50 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh F9 is approximately 60-80 kDa due to glycosylation.
  • Reconstitution: A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
  • Accession Number: AAB59620.1
  • Predicted N Terminal: Thr 29


A DNA sequence encoding the human F9 (AAB59620.1) (Met 1-Thr 461) was expressed, fused with a polyhistidine tag at the C-terminus.
