Synonyms
FST | Activin-binding protein | Follistatin isoform FST317 | Follistatin | Fs
Conjugations
Unconjugated
Applications
- Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis
Predicted Molecular Weight
The secreted recombinant human FST (FS288) consists of 299 amino acids and has a predicted molecular mass of 33 kDa. As a result of glycosylation, rhFST (FS288) migrates as an approximately 45 kDa band in SDS-PAGE under reducing conditions.
Expression System
HEK 293 Cells
Purification
> 90 % as determined by SDS-PAGE
Bio-Activity
Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation.The ED50 for this effect is typically 0.2-1 µg/mL in the presence of 10 ng/ml Recombinant Human Activin A.
Endotoxin
Less than 1.0 EU/µg protein (determined by LAL method).
Presentation
Lyophilized from sterile PBS, pH 7.4, with 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
