|Product Overview:||Recombinant Human IL18 (Tyr37-Asp193) with a 6His tag at the C-terminus was produced in HEK293 cell in an animal component free process under cGMP guidelines.|
|Description:||Interleukin-18 is a secreted protein and it belongs to the IL-1 family. IL-18 is a proinflammatory cytokine and produced by macrophages and other cells. This cytokine can induce the IFN-gamma production of T cells. The combination of this cytokine and IL12 has been shown to inhibit IL-4 dependent IgE and IgG1 production, and enhance IgG2a production of B cells. IL-18 binding protein (IL18BP) can specifically interact with this cytokine, and thus negatively regulate its biological activity. After stimulation with IL-18, natural killer (NK) cells and certain T cells release another important cytokine called interferon-γ (IFN-γ) or type II interferon that plays an important role in activating the macrophages or other cells.|
|Bio-activity:||Measured by its ability to induce NFKB reporter gene expression in HEK 293 cell line.
The ED50 for this effect is typically 25.3 ng/mL.
