CD25/IL2RA Protein, Human, Recombinant (ECD, His Tag): 产品信息

纯度:> 97 % as determined by SDS-PAGE. > 90 % as determined by SEC-HPLC.

内毒素:< 1.0 EU per μg of the protein as determined by the LAL method

生物活性:Measured by its ability to inhibit IL2-induced proliferation of M07e cells. The ED50 for this effect is 0.2-1.2 μg/mL in the presence of 30 ng/mL of recombinant human IL2.

蛋白构建:A DNA sequence encoding the extracellular domainof human IL2RA (Met1-Cys213) was expressed with a C-terminal polyhistidine tag.

表达宿主:HEK293 Cells

种属:Human

预测 N 端:Glu 22

分子量:The recombinant human IL2Rα consists of 203 amino acids and has a predicted molecular mass of 23.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhIL2Rα is approximately 44 kDa due to glycosylation.

缓冲液:Lyophilized from sterile PBS, pH 7.4

Please contact us for any concerns or special requirements.

Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Please refer to the specific buffer information in the hard copy of CoA.

运输方式:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.

Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

稳定性 & 储存条件:Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃

Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

复溶:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

注意事项:该产品仅供科研实验使用,未经允许不得用于其它用途!
