Detection Method:competitive
Test principle:This assay employs the competitive enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with an antibody specific to VC. Standards or samples are then added to the appropriate microtiter plate wells with a Horseradish Peroxidase (HRP)-conjugated VC and incubated. The competitive inhibition reaction is launched between with HRP labeled VC and unlabeled VC with the antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of VC in the sample. The color development is stopped and the intensity of the color is measured
Product Overview:Vitamin C is an essential nutrient for humans and certain other animal species, in which it functions as a vitamin. In living organisms, ascorbate is an anti-oxidant, since it protects the body against oxidative stress. It is also a cofactor in at least eight enzymatic reactions, including several collagen synthesis reactions that cause the most severe symptoms of scurvy when they are dysfunctional. In animals, these reactions are especially important in wound-healing and in preventing bleeding from capillaries. Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid. It is actively
imported into the endoplasmic reticulum of cells and generates the oxidative potential found there. Protein disulfide isomerases are known to reduce DHA
back to ascorbic acid, oxidizing their disulfide bonds in the process. Therefore L-dehydroascorbic acid is a vitamin C compound much like L-ascorbic acid.
