分子量（Molecular Weight）

The protein has a predicted MW of 24.93 kDa. Due to glycosylation, the protein migrates to 35-45 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 PD-L1, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-PD-L1 Antibody, hFc Tag with the EC50 of 3.2ng/ml determined by ELISA.

制剂（Formulation）

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