Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate DLD in samples. An antibody specific for DLD has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDLD present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DLD 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 DLD bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:The dihydrolipoate, still bound to a lysine residue of the complex, then migrates to the dihydrolipoyl dehydrogenase (E3) active site where it undergoes a flavin-mediated oxidation, identical in chemistry to disulfide isomerase. First, FAD oxidizes dihydrolipoate back to its lipoate resting state, producing FADH2.
Dihydrolipoamide dehydrogenase is the L protein of the mitochondrial glycine cleavage system. The L protein, also named dihydrolipoamide dehydrogenase, is also a component of the pyruvate dehydrogenase complex, the alpha-ketoglutarate dehydrogenase complex, and the branched-chain alpha-keto acide dehydrogenase complex. Mutations in this gene have been identified in patients with E3-deficient maple syrup urine disease and lipoamide dehydrogenase deficiency.
