分子量（Molecular Weight）

The protein has a predicted MW of 33.00 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Bis-Tris PAGE result.

内毒素（Endotoxin）

< 1 EU/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 IGFBP-3, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human IGF II, hFc Tag with the EC50 of 0.19μg/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.
