Product Information
KE00025 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The IL18 ELISA kit is to be used to detect and quantify protein levels of endogenous Pre-IL18 and mature IL18. The assay recognizes human IL18. An antibody specific for IL18 has been pre-coated onto the microwells. The IL18 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for IL18 is added to detect the captured IL18 protein. For signal development, horseradish peroxidase (HRP)-conjugated antibody 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 450nm with the correction wavelength set at 630 nm.

Background Information
IL-18 is a member of IL-1 superfamily of cytokines. IL-18 is expressed by many human lymphoid and nonlymphoid cells, and has an important role in inflammatory processes. It can stimulate the NK cells and certain T cells to release IFN gamma which plays an important role in activating the macrophages or other cells. IL-18 synergistically with IL-12 contributes to Th1 differentiation and, therefore, is important in host defense mechanisms against intracellular bacteria, viruses, and fungi. The IL-18 cytokine increased expression of vascular cell adhesion molecule-1(VCAM1) and the adherence of melanoma cells. IL-18 plays a major role in atherosclerotic plaque destabilization leading to acute ischemic syndromes. IL-18 negatively regulate NAFLD/NASH progression, as well as multiple aspects of metabolic syndrome via modulation of the gut microbiota. This kit is used to quantify Pre-IL18 and mature IL18 level in vivo.
