Product Information
KE10052 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The IL-1ra ELISA kit is to be used to detect and quantify protein levels of endogenous IL-1ra. The assay recognizes mouse IL-1ra. An antibody specific for IL-1ra has been pre-coated onto the microwells. The IL-1ra protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for IL-1ra is added to detect the captured IL-1ra protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
IL-1Ra, also known as IL-1F3, is a member of the interleukin 1 cytokine family. It is a receptor antagonist of IL-1, can competitively bind with IL-1R1 thereby blocking cell activation by the cytokine. IL-1Ra is secreted by various types of cells including immune cells, epithelial cells, and adipocytes, and is a natural inhibitor of the pro-inflammatory effect of IL1β. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses, particularly in the acute phase of infection and inflammation. As a potent immune/inflammatory molecule, IL-1Ra is tightly associated with osteomyelitis, rheumatoid arthritis, traumatic brain injury (TBI) and stroke. Recently, an increasing number of studies proved that IL-1Ra is also actively involved in tumor progression, such as high expression IL-1Ra increased the risk of bladder cancer and non-cardia gastric carcinoma.
