Anti-IL2RB antibodies are used in the immunodetection of the protein interleukin 2 receptor subunit beta. In humans, the canonical protein has a reported length of 551 amino acid residues and a mass of 61.1 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the tonsil, spleen, lymph node, endometrium, and bone marrow. A member of the Type I cytokine receptor protein family, IL2RB is a known receptor for interleukin-2. Post-translational modifications have been described, including glycosylation. IL2RB is also used as a cellular marker for characterizing NK T cells. Synonyms for this target antigen include IL15RB, IMD63, P70-75, CD122 antigen, IL-2 receptor subunit beta, and CD122. IL2RB gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 410 citations in the literature describe the use of IL2RB antibodies in research. Flow Cytometry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
