Description
Human IL-2 receptor alpha (IL-2 R alpha ), also known as Tac antigen and as CD25, was initially identified as a 55 kDa membrane glycoprotein that is capable of binding IL2. By itself, IL-2 R alpha binds IL-2 with low affinity.

|
Source |
Recombinant Human IL-2 R alpha/CD25 Protein is expressed from HEK293 cell with His tag and Avi tag at the C-terminal. It contains Glu22-Cys213. |
|
Molecular Weight |
The protein has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. |
|
Purity |
> 95% as determined by SDS-PAGE and HPLC. |
|
Endotoxin |
<1.0 EU per 1μg of the protein by the LAL method. |
|
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
|
Reconstitution |
Centrifuge tubes before opening. Dissolve lyophilized protein with sterile water to ensure the concentration is greater than 100 ug/mL. |
Storage
The product should be stored at -25~-15℃ for 1 year from the date of receipt.
2-7 days, 2 ~8 °C under sterile conditions after reconstitution.
3 months, -25~-15℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
