Product Specifications
Immunogen
S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL-2 R beta
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
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.
