Alternative Name Il18 (IL18 ELISA Kit Abstract)
Background Interleukin 18 (IL-18) is a 18 kDa novel cytokine which is identified as a costimulatory factor for production of interferon- γ (IFN- γ ) in response to toxic shock. It shares functional similarities with IL-12. IL-18 is synthesized as a precursor 24 kDa molecule without a signal peptide and must be cleaved to produce an active molecule. IL-1 ? converting enzyme (ICE, Caspase-1) cleaves pro-IL-18 at aspartic acid in the P1 position, producing the mature, bioactive peptide that is readily released from the cells. It has been reported that IL-18 is produced from Kupffer cells, activated macrophages, keratinocytes, intestinal epithelial cells, osteoblasts, adrenal cortex cells and murine diencephalon. IL-18 acts on T helper 1-type T (Th1) cells and in combination with IL-12 strongly induces production of IFN- γ by these cells. Pleiotropic effects of IL-18 have also been reported, including enhancement production of IFN- γ and GM-CSF in peripheral blood mononuclear cells, production of T helper type 1 cytokines, IL-2, GM-CSF and IFN- γ in T cells, enhancement of Fas ligand expression by T helper type 1 cells.
Pathways Cellular Response to Molecule of Bacterial Origin, Activated T Cell Proliferation
Sample Volume 100 μL
Plate Pre-coated
Protocol The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL-18. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for IL-18 and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain IL-18, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of IL-18 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
