IL‑1 RII Inhibition of IL‑1 beta /IL‑1F2-dependent Cell Proliferation and Neutralization by Human IL‑1 RII Antibody.

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 Human IL-1 RII Monoclonal Antibody (Catalog # MAB663). The ND50 is typically 5-20 µg/mL.

Detection of IL‑1 RII in HDLM-2 cells by Flow Cytometry

HDLM-2 cells were stained with Mouse Anti-Human IL‑1 RII Monoclonal Antibody (Catalog # MAB663, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).

Human IL-1 RII ELISA Standard Curve

Human IL-1 RII ELISA Standard Curve

Recombinant Human IL‑1 RII (Catalog # 263-2R) was serially diluted and captured by Mouse Anti-Human IL‑1 RII Monoclonal Antibody (Catalog # MAB663) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human IL‑1 RII Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-263-NA) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998)

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.
