| 目标/特异性 | Detects human IL‑18 R alpha /IL-1 R5 in direct ELISAs and Western blots. In direct ELISAs, approximately 5% cross-reactivity with recombinant mouse IL‑18 R alpha is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Flow Cytometry: 2.5 µg/106cells Immunohistochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize IL‑18/IL‑1F4-induced IFN‑ gamma secretion in the KG‑1 human acute myelogenous leukemia cell line. The Neutralization Dose (ND50) is typically 0.1-0.4 µg/mL in the presence of 40 ng/mL Recombinant Human IL‑18/IL‑1F4. |

| 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 IL-18 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 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 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. |

IL‑18 R alpha /IL‑1 R5 in Human Skin. IL‑18 R alpha /IL‑1 R5 was detected in immersion fixed frozen sections of human skin using Goat Anti-Human IL‑18 R alpha /IL‑1 R5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF840) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-AEC Cell & Tissue Staining Kit (red; Catalog # CTS009) and counterstained with hematoxylin (blue). Specific labeling was localized to the plasma membrane of keratinocytes. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections. | |
IFN‑ gamma Secretion Induced by IL‑18/IL‑1F4 and Neutralization by Human IL‑18 R alpha /IL‑1 R5 Antibody. Recombinant Human IL‑18/IL‑1F4 stimulates IFN‑ gamma secretion in the KG‑1 human acute myelogenous leukemia cell line, in a dose-dependent manner (orange line), as measured by the Human IFN‑ gamma Quantikine ELISA Kit (Catalog # DIF50). IFN‑ gamma secretion elicited by IL‑18/IL‑1F4 (40 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‑18 R alpha /IL‑1 R5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF840). The ND50 is typically 0.1-0.4 µg/mL. |
