Interleukin-18 (IL-18), also known as interferon-gamma inducing factor (IGIF), encoded by the IL18 gene, is a proinflammatory cytokine, belonging to the IL-1 superfamily. IL18 is produced mainly by macrophages but also other cell types, stimulates various cell types and has pleiotropic functions. In combination with IL12, IL18 acts on CD4, CD8 T cells and NK cells to induce IFNγ production and type II interferon that plays an important role in activating the macrophages or other cells. This combination of IL-18 and IL-12 inhibit IL-4 dependent IgE and IgG1 production and enhance IgG2a production in B cells. IL-18 can modulate both innate and adaptive immunity and its dysregulation can cause autoimmune or inflammatory diseases. This product is designed as a tool for the delivery and expression of human IL-18 mRNA for research. The product leverages the lipid nanoparticle (LNP) technology platform for simple and efficient delivery of hIL-18 mRNA to a variety of mammalian cells in vitro and in vivo. The LNPs used are formulated with SM-102, DSPC, cholesterol and DMG-PEG2000 at an optimal molar concentration for a high rate of encapsulation and efficient mRNA delivery. The IL-18 protein is about 21 kD and consists of 193 amino acids. The GenPept accession number is NP_001373349.

Application & Handing
Upon receiving product, briefly pulse spin before opening to ensure product is at bottom of container. It is important not to spin for too long as this may rupture mRNA-LNPs. Do not vortex. Work with mRNA-LNPs on ice and minimize the time that the product spends at room temperature. After handling the product during experiments, return immediately to ice. mRNA-LNP products should only be handled with certified RNase-free reagents and consumables. Use of filtered pipette tips is highly recommended.
