| Specificity Profile | More Information |
|
The specificity of IL2Ra Monoclonal Antibody (CSB0015) 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. |

HEK-293F cells transiently transfected with human IL2Ra were stained with IL2Ra Monoclonal Antibody (CSB0015) (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 (CSB0015) (blue). | |

CD25 (also known as 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.
