Product Specifications

Specificity

Detects human IL‑2 R beta in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross-reactivity withrecombinant human (rh) IL-2 R alpha, recombinant mouse (rm) IL-2 R beta, rhIL-2 R gamma, and rhIL-15 R is observed. Is also able to block the cell surface of human IL-2 R beta mediated bioactivities induced by IL-2. For optimal neutralization of IL-2 biological activity on cells expressing the high affinity IL-2 receptors, the use of anti-IL-2 R alpha in conjunction with anti-IL-2 R beta antibodies is recommended.

Background: IL-2 R beta

Functional IL-2 receptors can exist in two affinity states on cell surfaces, the high affinity complex consisting of heterotrimers of the alpha, beta, and gamma chains, and the intermediate affinity complex comprising heterodimers of the beta and gamma chains. Individual beta chains and alpha chains exhibit low affinity IL-2 binding and the gamma chain alone does not bind IL-2. In addition to their involvement in IL-2 mediated signal transduction, both the beta chain and gamma chain have been shown to be required for IL-15 mediated signaling.

IL-2 R beta is a member of the cytokine receptor superfamily. Human IL-2 R beta cDNA encodes a 551 amino acid residue precursor Type I membrane protein with a 26 residue signal peptide, a 214 residue extracellular region, a 25 residue transmembrane region and a 286 residue cytoplasmic domain. A soluble IL-2 R beta (IL-2 sR beta ) has been identified in the culture supernatants of a human lymphoid cell line, YT, that displays IL-2 R beta. At present, the function of IL-2 sR beta is unclear. Recombinant human IL-2 sR beta binds IL-2 with low affinity and is not an effective IL-2 antagonist on cells displaying the high or intermediate affinity IL-2 signaling receptors. Nevertheless, IL-2 sR beta binds IL-15 with sufficient affinity to neutralize IL-15 biological activities.
