| Background Information | Interleukin-2 receptor subunit beta (UniProt: P16297; also known as IL-2 receptor subunit beta, IL-2R subunit beta, IL-2RB, High affinity IL-2 receptor subunit beta, p70-75, CD122) is encoded by the Il2rb gene (Gene ID: 16185) in murine species. IL-2R is a non-covalent dimer of an alpha and a beta subunit. It can exist as a high affinity dimer, an intermediate affinity monomer of beta subunit, and as a low affinity monomer of alpha subunit. IL-2R beta is a single-pass type I membrane protein. The beta subunit is involved in receptor mediated endocytosis and it transduces the mitogenic signals of IL-2. IL-2R beta is synthesized with a signal peptide (aa 1-26), which is cleaved off to produce the mature form that has an extracellular domain (aa 27-240), a transmembrane domain (aa 241-268), and a long cytoplasmic domain (aa 269-539). IL-2R beta contains a WSXWS motif (aa 221-225), which is essential for its proper folding and thereby efficient intracellular transport. It also has a Box 1 motif (aa 281-289) that is required for JAK interaction and/or activation. |

| Application | Anti-IL-2R beta (CD122), clone TM-beta1, Cat. No. MABF951, is a rat monoclonal antibody that detects IL-2R beta and has been tested for use in Flow Cytometry, Function assay, Immunocytochemistry, Immunoprecipitation, Neutralizing, and Western Blotting. |
| Key Applications |
|
| Application Notes | Neutralizing Analysis: Freshly isolated mouse splenocytes pretreated with different amounts of MABF951, Anti-IL-2R beta (CD122), clone TM- 1 showed a co-relation of the amount of antibody used vs percent of cells stained with FITC-labeled antibody. In antibody titration, as the concentration of unlabeled anti-IL-2R beta (CD122) is decreased less inhibition is observed as a result. Inhibits Activity/Function: A representative lot abolished the binding of IL2 ligand to IL-2R beta (CD122). (Tanaka, T., et. al. (1991). J Immunol. 147(7):2222-8; Yokoyama, S., et. al. (2009). Proc Natl Acad Sci USA. 106(37):15849-54). Flow Cytometry Analysis: A representative lot detected IL-2R beta (CD122) in Flow Cytometry applications (Tanaka, T., et. al. (1991). J Immunol. 147(7):2222-8). Western Blotting Analysis: A representative lot detected IL-2R beta (CD122) in Western Blotting applications (Tanaka, T., et. al. (1991). J Immunol. 147(7):2222-8). Immunoprecipitation Analysis: A representative lot immunoprecipitated IL-2R beta (CD122) in Immunoprecipitation applications (Tanaka, T., et. al. (1991). J Immunol. 147(7):2222-8). Immunocytochemistry Analysis: A representative lot detected IL-2R beta (CD122) in Immunocytochemistry applications (Tanaka, T., et. al. (1991). J Immunol. 147(7):2222-8). |
