TNFSF18/GITRL, BioAssay(TM) ELISA Kit (Mouse)

Tumor necrosis factor ligand superfamily member 18, also known as AITRL or GITRL, is a protein that in humans is encoded by the TNFSF18 gene. The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor(TNF) ligand family. It is mapped to 1q25.1. TNFSF18 is a ligand for receptor TNFRSF18/AITR/GITR. It has been shown to modulate T lymphocyte survival in peripheral tissues. This cytokine is also found to be expressed in endothelial cells, and is thought to be important for interaction between T lymphocytes and endothelial cells. TNFSF18-dependent modulation of tryptophan catabolism may represent an important mechanism of action of glucocorticoids, both physiologically and therapeutically. Sample Type: Cell culture supernates, serum and plasma (heparin, EDTA), Intended Use: For quantitative detection of mouse TNFSF18 in cell culture supernates, serum and plasma (heparin, EDTA). Sensitivity: <10pg/ml, Range: 31.2-2000pg/ml, Specificity: Natural and recombinant mouse TNFSF18, Test Principle: This mouse TNFSF18 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for TNFSF18 has been precoated onto 96-well plates. Standards(NSO, T47-S173) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for TNFSF18 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse TNFSF18 amount of sample captured in plate.
