| Form : |
Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. |
| Bio-activity : |
Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation.The ED50 for this effect is typically 0.02-0.08 μg/mL in the presence of 10 ng/ml Recombinant Human Activin A. |
| Molecular Mass : |
The recombinant mouse FST comprises 326 amino acids and has a predicted molecular mass of 36.1 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rmFST is approximately 70-80 kDa due to glycosylation. |
| Proteinlength : |
Met1-Trp344 |
| Endotoxin : |
< 1.0 EU per μg of the protein as determined by the LAL method |
| Purity : |
> 98 % 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°C before opening to recover the entire contents. |
