Recombinant Human FST Protein, His-tagged

Cat.No.: FST-242H
Product Overview: Recombinant human FST (NP_037541.1) (Met1-Asp329) was expressed with a polyhistidine tag at the C-terminus.
Source: HEK293
Species: Human
Tag: His
Predicted N Terminal: Gly 30
Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
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.
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 4ºC before opening to recover the entire contents.
