应用 | Western Blot(0.1 µg/mL) Flow Cytometry(2.5 µg/106cells) |
目标/特异性 | Detects mouse IL‑18 R alpha in direct ELISAs and Western blots. In direct ELISAs, approximately 25% cross-reactivity with recombinant human IL‑18 R is observed. |
使用方法 | Western Blot: 0.1 µg/mL Flow Cytometry: 2.5 µg/106cells Neutralization: Measured by its ability to neutralize IL‑18/IL‑1F4-induced IFN‑ gamma secretion in activated mouse T cells. Ahn, H.J. et al. (1997) J. Immunol. 159:2125. The Neutralization Dose (ND50) is typically 0.2-0.8 µg/mL in the presence of 0.5 ng/mL Recombinant Mouse IL‑18/IL‑1F4 and 0.1 ng/mL Recombinant Mouse IL‑12. |

R&D Systems personnel manually curate a database that contains references using R&D Systems products. The data collected includes not only links to publications in PubMed, but also provides information about sample types, species, and experimental conditions. Increased cytokine production in IL-18 receptor alpha-deficient cells is associated with dysregulation of suppressors of cytokine signaling (SOCS). | |

背景 | Interleukin-18 (IL-18) is a member of the IL-1 family of cytokines and shares numerous immuno-regulatory functions with IL-12. The functional IL-18 receptor complex is composed of two subunits designated IL18 R alpha (also termed IL-1 R5 and IL-1 Rrp) and IL-18 R beta (also termed IL-1 R7 and AcPL). Both IL-18 R alpha and IL-18 R beta belong to the IL-1 receptor superfamily. Although IL-18 R by itself binds IL-18 with low affinity and IL-18 R beta does not bind IL18 in vitro, coexpression of IL-18 R alpha and IL18 R beta is required for high affinity binding and IL-18 responsiveness. Human IL-18 R cDNA encodes a 541 amino acid (aa) precursor type I membrane protein with a hydrophobic signal, an extracellular domain comprised of three immunoglobulin-like domains, a transmembrane domain and a cytoplasmic region of approximately 200 aa residues. Human and mouse IL-18 R share 65% amino acid sequence homology. IL-18 R is widely expressed in numerous tissues including spleen, thymus, leukocyte, liver, lung, heart, small and large intestine, prostate and placenta. |

IFN‑ gamma Secretion Induced by IL‑18/IL‑1F4 and Neutralization by Mouse IL‑18 R alpha /IL‑1 R5 Antibody. In the presence of Recombinant Mouse IL‑12 (0.1 ng/mL, Catalog # 419-ML), Recombinant Mouse IL‑18/IL‑1F4 stimulates IFN‑ gamma secretion in activated mouse T cells in a dose-dependent manner (orange line), as measured by the Mouse IFN‑ gamma Quantikine ELISA Kit (Catalog # MIF00). Under these conditions, IFN‑ gamma secretion elicited by Recombinant Mouse IL‑18/IL‑1F4 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IL‑18 R alpha /IL‑1 R5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF856). The ND50 is typically 0.2-0.8 µg/mL. |
