Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate IL-1β in samples. An antibody specific for IL-1β has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyIL-1β present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL-1β 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 IL-1β 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.
