Mouse IL-12 R beta 2 Antibody Summary

Species Reactivity
Detects mouse IL-12 R beta 2 in direct ELISAs.
Monoclonal Rat IgG2B Clone # 918102
Protein A or G purified from hybridoma culture supernatant
Mouse myeloma cell line NS0-derived recombinant mouse IL-12 R beta 2
Accession # P97378
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Blockade of Receptor-ligand Interaction
In a functional ELISA, 30-180 ng/mL of this antibody will block 50% of the binding of 100 ng/mL of Recombinant Mouse IL‑12 (Catalog # 419-ML) to immobilized Recombinant Mouse IL-12 R beta 2 Fc Chimera (Catalog # 7406-MR) coated at 500 ng/mL (100 μL/well). At 1 μg/mL, this antibody will block >90% of the binding.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: IL-12 R beta 2

The high‑affinity IL‑12 receptor complex includes the 100 kDa IL‑12 receptor beta 1 (IL‑12 R beta 1) and the 130 kDa IL‑12 Receptor  beta 2 (IL‑12 R beta 2) subunits, both of which are type I transmembrane proteins that belong to the cytokine receptor superfamily (1, 2). The complex's ligand, IL‑12, is a disulfide‑linked heterodimer composed of 35 kDa (IL‑12 alpha  p35) and 40 kDa (IL‑12 beta  p40) subunits. IL‑12 R beta 2 binds IL‑12 alpha and signals through Jak2, while IL‑12 R beta 1 binds IL‑12 beta and signals through Tyk2 (3).
IL‑12 R beta 1 is also a subunit of the IL‑23 receptor complex (3). The 874 amino acid (aa) mouse IL‑12 R beta 2 precursor includes a 23 aa signal peptide, a 614 aa extracellular domain (ECD), a 21 aa transmembrane segment and a 216 aa cytoplasmic region. The ECD possesses one C2‑type Ig‑like domain, five fibronectin type III (Fn III) repeats, 14 potential N‑glycosylation sites, and a WSXWS motif, while the cytoplasmic region contains a Box 1 motif and three tyrosine phosphorylation sites that presumably mediate intracellular signaling (3). The mouse IL‑12 R beta 2 ECD shares 91% aa sequence identity with rat IL‑12 R beta 2, and 68% with human, porcine and bovine IL‑12 R beta 2. Human and mouse IL‑12 R beta 2 do not bind cross‑species IL‑12 (2). A 734 aa mouse isoform that lacks aa 363-503 within the Fn III domains is reported (4). Unlike IL‑12 R beta 1, which is constitutively expressed on T cells, NK cells and B cells, IL‑12 R beta 2 expression is more restricted (2). On naïve T cells, IL‑12 R beta 2 is expressed following STAT1 activation by IFN‑ gamma, IL‑27 and/or T cell receptor ligation. This up‑regulation allows IL‑12 to promote Th1, but not Th2, differentiation (5-7). Among B cells, surface expression is limited to naïve germinal center and memory B cells, and myeloma cells (2). Deletion of IL‑12 R beta 2 causes systemic overexpression of IL‑6, accelerated maturation of thymocytes, deficient regulatory T cell maturation and function, and reduced splenic T cell apoptosis (2, 8-10). These mice are susceptible to autoimmune diseases such as experimental autoimmune encephalitis and spontaneous B cell malignancies
(2, 8-10). In humans, polymorphism of the IL‑12 R beta 2 gene is associated with systemic sclerosis (11).
