Human IL-2 R beta / CD122 Protein, His Tag (SPR verified)
IL2RB,RP5-1170K4.6,CD122,P70-75
Human IL-2 R beta, His Tag (SPR verified) is expressed from human 293 cells. It contains AA Ala 27 - Asp 239 ).
Predicted N-terminus: Ala 27
Request for sequence
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 25.4 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Contact us for customized product form or formulation.
Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to -70°C for 12 months in lyophilized state;
-70°C for 3 months under sterile conditions after reconstitution.
Human IL-2 R beta, His Tag (SPR verified) on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
