This antibody recognises the CD122 cell surface glycoprotein. Clone TM-beta 1 is reported to block IL-2 high affinity binding to the IL-2R beta receptor. We recommend the use of SM2224LE for this purpose.

CD122 is a 75-85kD molecule also known as interleukin-2 receptor (IL-2R) beta chain. In mouse, CD122 is primarily expressed on natural killer (NK) cells and at lower levels on lymphocyte subsets, monocytes and macrophages. CD122 can associate with the IL-2R alpha chain (CD25) and CD132 to form a functional high affinity receptor complex that binds IL-2. CD132/CD122 heterodimers can also be formed which bind IL-2 with intermediate affinity. IL-2 binding to the IL-2R is important in the generation and differentiation of T lymphocytes and NK cells.Synonyms: IL-2 receptor subunit beta, IL2 Receptor beta, Interleukin-2 receptor subunit beta, P70-75
