Active Recombinant Human FST Protein, His-tagged

• Cat.No.: FST-242H
• Product Overview: Active Recombinant Human FST Protein(NP_037541.1) (Met1-Asp329) was expressed in HEK293 with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-329 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation. The ED50 for this effect is typically 5-40ng/mL.
• Molecular Mass: The recombinant human FST consists 311 amino acids and predicts a molecular mass of 34.4 kDa.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 85 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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.
