  • Product overview

    GITR in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of GITR protein in human serum, plasma, cell culture supernatant and cell extract.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB Development Solution is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

    Glucocorticoid-induced tumor necrosis factor receptor (GITR) is a receptor for GITRL. GITR exists both as a membrane bound receptor protein and a soluble receptor. GITR is expressed mainly on regulatory T-cells (Treg). GITR can induce Treg proliferation, but also inhibits the ability of Treg to suppress the immune response, this can lead to autoimmunity and inflammation.

  • Research areas

  • Function

    Receptor for TNFSF18. Seems to be involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. Mediated NF-kappa-B activation via the TRAF2/NIK pathway.
  • Tissue specificity

    Expressed in lymph node, peripheral blood leukocytes and weakly in spleen.
  • Sequence similarities

    Contains 3 TNFR-Cys repeats.
  • Cellular localization

    Secreted and Cell membrane.

Sandwich ELISA Use at an assay dependent concentration.


  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

  • The concentrations of GITR were measured in duplicates, interpolated from the GITR standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 50%, plasma (EDTA) 25%, plasma (citrate) 25%, plasma (heparin) 25% and cell culture media 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).

  • The concentrations of GITR were measured in duplicate and interpolated from the GITR standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean GITR concentration was determined to be 757 pg/mL in MCF7 cell extract.
