Tumor Necrosis Factor Receptor Superfamily Member 17 (TNFRSF17) BioAssay(TM) ELISA Kit (Human)

This protein is a member of the TNF-receptor superfamily. This receptor is preferentially expressed in mature B lymphocytes, and may be important for B cell development and autoimmune response. This receptor has been shown to specifically bind to the tumor necrosis factor (ligand) superfamily, member 13b (TNFSF13B/TALL-1/BAFF), and to lead to NF-kappaB and MAPK8/JNK activation. This receptor also binds to various TRAF family members, and thus may transduce signals for cell survival and proliferation. Sample Type: Serum, plasma, tissue homogenates, Intended Use: For the quantitative determination of human tumor necrosis factor receptor superfamily member 17 (TNFRSF17) concentrations in serum, plasma, tissue homogenates. Sensitivity: 1.95pg/ml, Range: 7.81-500pg/ml, Specificity: This assay has high sensitivity and excellent specificity for detection of human TNFRSF17. No significant cross-reactivity or interference between human TNFRSF17 and analogues was observed. Test Principle: This BioAssay(TM) employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for TNFRSF17 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TNFRSF17 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TNFRSF17 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TNFRSF17 bound in the initial step. The color development is stopped and the intensity of the color is measured.
