TNFRSF25/DR3 BioAssay(TM) ELISA Kit (Human)

Death receptor 3 (DR3), also known as tumor necrosis factor receptor superfamily member 25 (TNFRSF25), is a cell surface receptor of the tumor necrosis factor receptor superfamily which mediates apoptotic signalling and differentiation. Knockout studies in mice suggested the role of this gene in the removal of self-reactive T cells in the thymus. Multiple alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported, most of which are potentially secreted molecules. The alternative splicing of this gene in B and T cells encounters a programmed change upon T-cell activation, which predominantly produces full-length, membrane bound isoforms, and is thought to be involved in controlling lymphocyte proliferation induced by T-cell activation. Sample Type: Cell lysates, cell culture supernates, serum, plasma (Heparin or EDTA). Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Human TNFRSF25/DR3. Sensitivity: <10pg/ml, Range: 312pg/ml-20,000pg/ml, Specificity: Recognizes natural and recombinant Human TNFRSF25/DR3. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Human TNFRSF25/DR3 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune- sorbent assay technology. A monoclonal antibody from mouse specific for TNFRSF25/DR3 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: Q25-F201) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for TNFRSF25/DR3 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 Human TNFRSF25/DR3 amount of sample captured in plate.
