Background of IL-18/IL-1F4

Interleukin-18 also known as IL18 is a protein which in humans is encoded by the IL18 gene. The protein encoded by this gene is a proinflammatory cytokine.IL-18 is a cytokine produced by macrophages and other cells that belongs to the IL-1 superfamily. IL-18 works by binding to the interleukin-18 receptor, and together with IL-12 it induces cell-mediated immunity following infection with microbial products like lipopolysaccharide (LPS). After stimulation with IL-18, natural killer (NK) cells and certain T cells release another important cytokine called interferon-gamma (IFN-gamma) or type II interferon that plays an important role in activating the macrophages or other cells.The combination of this cytokine and IL12 has been shown to inhibit IL4 dependent IgE and IgG1 production, and enhance IgG2a production in B cells. IL-18 binding protein (IL18BP) can specifically interact with this cytokine, and thus negatively regulate its biological activity. The human interleukin 18 gene IL18 maps to 11q22.2-q22.3, closely linked to the DRD2 gene locus and distinct from mapped IDDM loci.

5 Customer Q&As for Anti-Interleukin-18 IL18 Antibody


Can RP1017 detect pro-IL18 ( precursor) or mature IL-18 (active form)?

Verified customer

We are currently using anti-IL18 antibody RP1017 for mouse tissue, and we are happy with the IHC results. The species of reactivity given in the datasheet says mouse. Is it possible that the antibody can work on goat tissues as well?

Verified Customer

Asked: 2020-02-14


The anti-IL18 antibody (RP1017) has not been tested for cross reactivity specifically with goat tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in goat you can get your next antibody for free. Please contact me if I can help you with anything.
