Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PTS in samples. An antibody specific for PTS has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPTS present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PTS is added to the wells. After washing, Streptavidin 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 PTS bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:In enzymology, a 6-pyruvoyltetrahydropterin synthase (PTPS) (EC 4.2.3.12) is an enzyme that catalyzes the following chemical reaction:
7,8-Dihydroneopterin triphosphate {\displaystyle \rightleftharpoons } \rightleftharpoons 6-pyruvoyltetrahydropterin + triphosphate
Hence, this enzyme has one substrate, 7,8-Dihydroneopterin triphosphate, and two products, 6-pyruvoyltetrahydropterin and triphosphate.
