Interleukin 18 (IL-18) is a proinflammatory cytokine that participates in both innate and acquired immunity. IL-18 is a part of the IL-1 superfamily that activates T-helper 1 (Th1) and natural killer (NK) cells by inducing IFN-γ production. IL-18 is produced in its inactive precursor form, pro-IL-18 (24 kD), with no signal peptide, accumulating in the cytoplasm. Pro-IL-18 is then processed intracellularly by CASP1 into the mature active form of IL-18 (18 kD) which is secreted extracellularly. Mature IL-18 binds to an inducible receptor, IL-18Rα, and then recruits IL-18Rβ which initiates an immune reaction through TLR/IL-1R-like signaling by recruiting MyD88 and the NF-κB pathway. IL-18 is associated with Adult-onset Still's disease and pleural tuberculosis.Product Details

WB - Quality tested
ICC - Verified
- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.125 - 1.0 µg/mL. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Clone recognizes human IL-18.
For ICC testing, HeLa cells were fixed in 4% PFA and permeabilized with either Triton X-100 or methanol; both methods produced strong staining at 1 mg/mL.
