| Protein Length : |
1-134 a.a. |
| Form : |
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. |
| Bio-activity : |
1. Measured by its ability to neutralize Activin-mediated inhibition on MPC11 cell proliferation. The ED50 for this effect is typically 0.02-0.1 μg/mL in the presence of 10 ng/mL recombinant Activin A. 2. Measured by its binding ability in a functional ELISA. Immobilized Inhibin Human, Mouse, Rat, Cynomolgus, Rhesus Inhibin beta A/Activin A at 2 μg/ml (100 μl/well) can bind Human ACVR2B hFc, the EC50 of Human ACVR2B hFc is 12-60 ng/mL. |
| Molecular Mass : |
The recombinant human ACVR2B/Fc chimera is a disulfide-linked homodimer generated after removal of the signal peptide. The reduced monomer comprises 354 amino acids and predicts a molecular mass of 40.0 kDa. As a result of glycosylation, the monomer migrates as an approximately 60-65 kDa protein in SDS-PAGE under reducing conditions. |
| Endotoxin : |
< 1.0 EU per μg of the protein as determined by the LAL method |
| Purity : |
> 97 % 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. |
