分子量（Molecular Weight）

The protein has a predicted MW of W 39.35 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on Bis-Tris PAGE result.

内毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

纯度（Purity）

> 95% as determined by Bis-Tris PAGE;
> 95% as determined by HPLC

活性（Activity）

ELISA Data: Immobilized Human Activin A, No Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human Activin RIIA, hFc Tag with the EC50 of 1.6ng/ml determined by ELISA . ELISA Data: Immobilized Human/Mouse/Rat GDF-8, No Tag at 2 μg/ml (100 μl/well) on the plate. Dose response curve for Human Activin RIIA, hFc Tag with the EC50 of 0.13 μg/ml determined by ELISA.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
