    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 產品描述：

    The DNA fragment encoding the human TNFSF18 (Gln72-Ser199) was expressed with a C-terminal hFc-Flag-tag in the mammalian cells. The expressed protein is the recombinant human TNFSF18 protein with low endotoxin (< 1.0 EU/µg protein, LAL method) and high purity (> 94%, SDS-PAGE). This TNFSF18 protein displayed a molecular weight of approximately 45 kDa on the gel due to glycosylation. It is biologically active. In the functional ELISA, TNFRSF18 can bind to TNFSF18, with the EC50 is 2.565 to 2.940 ng/ml. In the LSPR assay, the human TNFRSF18 protein can bind to this TNFSF18 protein, with an affinity constant of 38.5 nM. This recombinant TNFSF18 protein is in stock now.

    TNFSF18, also called GITRL, is expressed in APCs and functions as a costimulatory molecule in the immune system. TNFSF18 engagement with its cognate receptor TNFRSF18 promotes proliferation and cytokine production of both CD4+ Teff and Treg cells, as well as drives the antitumor activity of CD8+ T cells. Besides, TNFRSF18/TNFSF18 signaling is implicated in the pathogenesis of inflammation, autoimmune diseases, and tumor.

靶點詳情

  • 功能：
    Cytokine that binds to TNFRSF18/AITR/GITR. Regulates T-cell responses. Can function as costimulator and lower the threshold for T-cell activation and T-cell proliferation. Important for interactions between activated T-lymphocytes and endothelial cells. Mediates activation of NF-kappa-B. Triggers increased phosphorylation of STAT1 and up-regulates expression of VCAM1 and ICAM1. Promotes leukocyte adhesion to endothelial cells. Regulates migration of monocytes from the splenic reservoir to sites of inflammation.
