标签(Tag)

None

外观(Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

纯度(Purity)

> 95% as determined by SDS-PAGE

生物活性(Biological Activity)

Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50 for this effect is < 0.4 ng/mL.

内毒素(Endotoxin)

< 1.0 EU per 1μg of the protein by the LAL method.

制剂(Formulation)

Lyophilized after extensive dialysis against PBS.

复溶(Reconstitution)

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute the lyophilized powder in ddH₂O or PBS up to 100 μg/ml.For long term storage it is recommended that a carrier protein (example 0.1% BSA) be added. Avoid repeated freeze-thaw cycles.

 

储存条件

产品用冰袋装运,从收到之日起可在-80℃下保存1年。 1周,复溶后在无菌条件下2至8°C。 复溶后在-20°C无菌条件下保存3个月。 建议第一次使用时将蛋白质分成较小的量,并避免反复冻融循环。
