表达系统（Source）

HEK293

表达序列（Sequence）

Ser21-Ser426

Accession

P08476

标签（Tag)

N-His

分子量（Molecular Weight）

The protein has a predicted MW of 13.0 kDa (mature form) and 32.0 kDa (pro form). Due to glycosylation and interchain disulfide bond, the protein migrates to 15 kDa (mature form) and 40-50 kDa (pro form) under reduced (R) condition 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

活性（Activity）

Cell Based Assay: Measured by its ability to inhibit proliferation of MPC-11 cells. The ED50?for this effect is 30-40 ng/mL.

制剂（Formulation）

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

外观（Appearance）
