The Bioaim Human IL-1 sRII ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of IL-1 sRII in Human serum, plasma and cell culture media. An antibody specific for Human IL-1 sRII was coated on a 96-well plate. Standards and samples are added to the wells and any IL-1 sRII present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human IL-1 sRII antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of IL-1 sRII present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Inflammation;
Interleukin-1 receptor type 2(IL-1 sRII) Background: 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. The two receptor types do not heterodimerize in a receptor complex. IL-1 RII binds interleukin-1α (IL1A), interleukin-1β (IL1B), and interleukin 1 receptor antagonist (IL1Ra), preventing them from binding to their regular receptors and thereby inhibiting the transduction of their signaling. IL-1R2 protein also interacts non-productively with the second component of the signalling IL-1 receptor, namely IL-1RAcP, and a complex of the IL-1R2 and IL-1RAcP extracellular domains with interleukin-1 beta has been solved by X-ray crystallography.
