Anti-IL2R antibodies enable researchers to detect and measure the IL2R antigen in biological samples. This target is a reported synonym of the IL2RA gene, which encodes interleukin 2 receptor subunit alpha. This protein is known to function in the apoptotic pathway and receptor-mediated signaling pathways, among other biological roles. The human version of IL2R has a canonical amino acid length of 272 residues and a protein mass of 30.8 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the tonsil, spleen, lymph node, and cerebellum. Other names for this target antigen include CD25 and IDDM10. These IL2R antibodies are widely used in Flow Cytometry experiments, among other applications.
