| Specificity Profile | More Information |
 | The specificity of IL2RA Monoclonal Antibody (CSB0026) was tested on the Membrane Proteome Array and shown to be specific for human IL2RA. The Membrane Proteome Array contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |
| Application | Conditions | Recommended Concentration |
| Flow Cytometry, Extracellular | Live, Unpermeabilized | 1 µg/mL |
 | HEK-293F cells transiently transfected with human IL2RA were stained with IL2RA Monoclonal Antibody (CSB0026) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with IL2RA Monoclonal Antibody (CSB0026) (blue). | |

Stable for 12 months from date of receipt when stored at 4°C. Avoid repeated freeze-thaw cycles.
IL2-Ra is a single-pass transmembrane protein and the alpha chain of the high-affinity IL2 receptor, which also includes beta and gamma chains. CD25 is involved in the regulation of immune tolerance. Severe COVID-19 causes elevated levels of IL2R in plasma, and elevated IL2R in serum is associated with some types of carcinomas. (NCBI Gene: 3559, UniProtKB/Swiss-Prot: P01589). This antibody uses the same variable regions as the clinical Daclizumab antibody. Daclizumab is indicated to treat relapsing-remitting forms of multiple sclerosis (https://medlineplus.gov/druginfo/meds/a616036.html). Other names: CD25, IDDM10, IL2R, P55, IMD41, TCGFR
