Human IL-1 RII Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL-1 RII in direct ELSAs and Western blots. When used in combination with the biotinylated human IL-1 RII affinity purified polyclonal detection antibody (Catalog # BAF263) in sandwich ELISAs, no significant cross-reactivity or interference was observed with recombinant human (rh) IL-1ra, rhIL-1 RI,  recombinant mouse IL-1ra,  or recombinant rat IL-1ra.

ELISA Capture (Matched Antibody Pair)
2-8 µg/mL 

Use in combination with:

Detection Reagent: Human IL‑1 RII Biotinylated Antibody (Catalog # BAF263)

Standard: Recombinant Human IL-1 RII Protein (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 5-20 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 (Catalog # 263-2R) inhibits Recombinant Human IL-1 beta /IL-1F2 (Catalog # 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 Human IL-1 RII Monoclonal Antibody (Catalog # MAB663). The ND50is typically 5-20 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.
