Rat cADPRH (Cyclic ADP Ribose Hydrolase) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat cADPRH. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat cADPRH. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat cADPRH, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat cADPRH in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Synthesizes the second messengers cyclic ADP-ribose and nicotinate-adenine dinucleotide phosphate, the former a second messenger for glucose-induced insulin secretion, the latter a Ca(2+) mobilizer (PubMed:11829748). Also has cADPR hydrolase activity (By similarity) , Regulates osteoclastic bone resorption, probably via production of cyclic ADP-ribose and triggering of a cytosolic calcium ion signal through ryanodine receptor activation [The Uniprot Consortium]
