Human IL-18 R beta /IL-1 R7 PE-conjugated Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL‑18 R beta /IL‑1 R7 in direct ELISAs and Western blots. In direct ELISAs, 15% cross-reactivity with recombinant human (rh) IL‑1 RII is observed and 2% cross-reactivity with rhIL-1 R9 is observed. Also in direct ELISAs, no cross-reactivity  with rhIL-1 RI, rhIL‑1 RacP/IL‑1 R3, rhIL-1 R4, rhIL-18 R alpha /IL-1 R5, rhIL-1 R6, rhIL-1 R8, or recombinant mouse (rm) IL-18 R beta /IL-1 R7 is observed. In Western blots, approximately 100% cross-reactivity with rmIL-18 R beta is observed and no cross-reactivity with rhIL-18 R alpha /IL-1 R5, rhIL‑1 RacP/IL‑1 R3, rhIL-1 RI, rhIL-1 RII, or rhIL-1 Rrp2/IL-1 R6 is observed.

Background: IL-18 R beta/IL-1 R7

IL-18, originally described as an interferon-gamma inducing factor (IGIF), is a member of the IL-1 family of cytokines that has multiple immunoregulatory functions. It has potent IFN-gamma inducing activities and plays a key role in the activation of T helper type 1 (Th1) responses. The functional IL-18 receptor complex consists of two components, the IL‑18 R alpha (IL-1 R5) and IL-18 R beta (also termed IL-1 R7 and AcPL) subunits. Both subunits are members of the IL-1 receptor superfamily. Although IL‑18 R alpha by itself binds IL-18 with low-affinity and IL-18 R beta does not bind IL-18 in vitro, co-expression of IL‑18 R alpha and IL-18 R beta is required for high-affinity binding and IL-18 responsiveness. Human IL-18 R beta cDNA encodes a 599 amino acid (aa) residue precursor type I membrane protein with a 14 aa signal peptide, a 342 aa extracellular region containing three immunoglobulin-like domains, a single transmembrane domain and a 222 aa cytoplasmic domain. Human and mouse IL-18 R beta share 65% aa sequence identity. The expression of IL-18 R beta parallels that of IL-18 R alpha and is detected in numerous tissues including lung, spleen, leukocytes and colon.
