Recombinant Human Activin A Protein

产品参数

Accession

P08476

表达系统(Source)

Human Activin A Protein is expressed from HEK293 without tag.

It contains Gly311-Ser426.

分子量大小(Molecular Weight)

The protein has a predicted MW of 12.97 kDa. Due to glycosylation, the protein migrates to 14-15 kDa under reduced (R) condition, and 23-25 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.

纯度(Purity)

> 95% as determined by Tris-Bis PAGE

生物活性(Biological Activity)

Measured by its ability to inhibit proliferation of MPC-11 cells. The ED50 for this effect is < 7 ng/mL.

内毒素(Endotoxin)

Less than 0.1EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in 4mM HCI. Normally 8% trehalose is added as protectant before lyophilization.

复溶(Reconstitution)

开盖之前,先离心。使用4mM HCl复溶至浓度不低于0.1 mg/mL。

 

储存条件

-25~-15℃保存,收到货之后有效期1年。

复溶后, 2 ~8 °C保存,7天有效期。复溶后, -85~-65℃保存,3个月有效期。

建议首次使用时将蛋白等分,避免重复冻融循环。
