Human IL-18 Protein, premium grade

GMP version GMP-L18H16 is now available for seamless transition.
  • Synonym
    IL-18,Interleukin-18,IL18,IL-1 gamma,IGIF,IL1F4,IL-1F4
  • 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).
    Human IL-18 Protein, premium grade (IL8-H5114), designed for preclinical stage, has the same activity and performance with GMP Human IL-18 Protein (GMP-L18H16), which enables a seamless transition from preclinical development to clinical phases. Premium Grade product offer a cost efficient alternative of GMP Grade products for the early development phase when safety of raw materials is not top priority. By using Premium Grade products in early development phase, you can transition easily into clinical and commercial phase without need to revalidate the raw materials and modify manufacturing process.

  • 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.
