Human IL-18 Protein, premium grade
分子別名（Synonym）
IL-18,Interleukin-18,IL18,IL-1 gamma,IGIF,IL1F4,IL-1F4
表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）
Human IL-18 Protein, premium grade (IL8-H5114) is expressed from E. coli cells. It contains AA Tyr 37 - Asp 193 (Accession # Q14116-1).
該產(chǎn)品是在我們嚴(yán)格的質(zhì)量控制體系下生產(chǎn)的，該體系包含一套全面的測(cè)試，包括無菌和內(nèi)毒素測(cè)試。在早期臨床前階段，產(chǎn)品性能經(jīng)過仔細(xì)驗(yàn)證和測(cè)試，以確保其與細(xì)胞培養(yǎng)用途或任何其他應(yīng)用的兼容性。
GMP-L18H16是IL8-H5114的GMP版本。這兩種蛋白質(zhì)顯示出無法區(qū)分的性能特征，從而確保最終用戶從早期臨床前階段無縫過渡到后期臨床階段。

背景（Background）
Interleukin-18 (IL-18) is a potent proinflammatory cytokine that induces interferon-gamma (IFN-gamma) production from Th1 cells, NK cells and activated macrophages, particularly in the presence of IL-12. IL-18 also functions in developmental regulation of T-lymphocyte helper type I cells and in Fas-mediated cytotoxicity. Suppression of IL-18 activity is being investigated for treatment of chronic inflammatory diseases such as Crohn's disease and rheumatoid arthritis. It acts by inducing heterodimerization of the two subunits of its receptor, IL-18RAlpha and IL-18RBeta shows structural similarity to IL-1.
