Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate UXS1 in samples. An antibody specific for UXS1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyUXS1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for UXS1 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 UXS1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:UDP-glucuronate decarboxylase (UGD; EC 4.1.1.35) catalyzes the formation of UDP-xylose from UDP-glucuronate. UDP-xylose is then used to initiate glycosaminoglycan biosynthesis on the core protein of proteoglycans.
The topology of the deduced 420-amino acid protein was consistent with a type II transmembrane protein. Northern blot analysis of rat tissues detected a single UGD transcript with highest levels in heart, brain, and testes. Substantial levels were also detected in kidney, liver and lung, and lower levels in spleen and skeletal muscle. Western blot analysis demonstrated highest levels of the protein in kidney, liver, and brain, with negligible staining in heart, spleen, skeletal muscle, lung, and testes. Subcellular studies and histochemistry localized the protein to the perinuclear Golgi.
