Human IL-1 RII Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL‑1 RII in direct ELISAs and Western blots. In direct ELISAs, less than 1% cross‑reactivity with recombinant human (rh) IL‑1 alpha, rhIL‑1 RI, recombinant mouse (rm) IL‑1 alpha, rhIL‑1 beta, rmIL‑1 beta, recombinant rat IL‑1 beta, rhIL‑1ra, rmIL‑1ra, and recombinant rhesus monkey IL‑1ra is observed.
Source
Polyclonal Goat IgG
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. See Certificate of Analysis for details.
*Small pack size (-SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Label
Unconjugated

Applications

Recommended Concentration
Sample
Western Blot
0.1 µg/mL
Recombinant Human IL‑1 RII (Catalog # 263-2R)
Neutralization
Measured by its ability to neutralize IL‑1 RII-mediated inhibition of proliferation in the D10.G4.1 mouse helper T cell line. The Neutralization Dose (ND50) is typically 15-30 µg/mL in the presence of 2 µg/mL Recombinant Human IL‑1 RII, 50 pg/mL Recombinant Human IL‑1 beta /IL‑1F2.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

IL‑1 RII Inhibition of IL‑1 beta /IL‑1F2-dependent Cell Proliferation and Neutralization by Human IL‑1 RII Antibody. Recombinant Human IL-1 RII (263-2R) inhibits Recombinant Human IL-1 beta /IL-1F2 (201-LB) induced proliferation in the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human IL-1 beta /IL-1F2 (50 pg/mL) activity elicited by Recombinant Human IL-1 RII (2 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL-1 RII Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-263-NA). The ND50 is typically 15‑30 µg/mL.

Background: IL-1 RII

Two distinct types of receptors that bind the pleiotropic cytokines IL-1 alpha and IL-1 beta have been described. The IL-1 receptor type I is an 80 kDa transmembrane protein that is expressed predominantly by T cells, fibroblasts and endothelial cells. IL-1 receptor type II is a 68 kDa transmembrane protein found on B lymphocytes, neutrophils, monocytes, large granular leukocytes and endothelial cells. Both receptors are members of the immunoglobulin superfamily and show approximately 28% sequence similarity in their extracellular domains. The two receptor types do not heterodimerize in a receptor complex.

An IL-1 receptor accessory protein that can heterodimerize with the type I receptor in the presence of IL-1 alpha or IL-1 beta but not IL-1ra, was identified (1). This type I receptor complex appears to mediate all the known IL-1 biological responses. The receptor type II has a short cytoplasmic domain and does not transduce IL-1 signals. In addition to the membrane-bound form of IL-1 RII, a naturally-occurring soluble form of IL-1 RII has been described. It has been suggested that the type II receptor, either as the membrane-bound or as the soluble form, serves as a decoy for IL-1 and inhibits IL-1 action by blocking the binding of IL-1 to the signaling type I receptor complex. Recombinant IL-1 soluble receptor type II is a potent antagonist of IL-1 action.
