Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate IL1B in samples. An antibody specific for IL1B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyIL1B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL1B is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IL1B bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Interleukin-1 (IL-1) is one of the first cytokines ever described. Its initial discovery was as a factor that could induce fever, control lymphocytes, increase the number of bone marrow cells and cause degeneration of bone joints. At this time, IL-1 was known under several other names including endogenous pyrogen, lymphocyte activating factor, haemopoetin-1 and mononuclear cell factor, amongst others. It was around 1984-1985 when scientists confirmed that IL-1 was actually composed of two distinct proteins, now called IL-1α and IL-1β.These belong to a family of cytokines known as the interleukin-1 superfamily.Both IL-1α and IL-1β are produced by macrophages, monocytes and dendritic cells.
