Principiul testului

Dexamethasone ELISA Test Kit (A327198) employs the competitive enzyme immunoassay technique for the quantitative measurement of Dexamethasone in meat, liver, and milk. The 96-well microtiter plate has been pre-coated with Dexamethasone. During the incubation, Dexamethasone present in the samples or standards competes with the fixed amount of immobilized Dexamethasone for binding sites of the Anti-Dexamethasone Antibody, a HRP-Conjugated Secondary Antibody is added to the wells at the same time. The more Dexamethasone present in a sample or standard, the less Anti-Dexamethasone Antibody that binds to the plate. Following incubation, unbound HRP-Conjugated Secondary Antibody is removed by washing. Following incubation and washing, TMB substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is inversely proportional to the amount of Dexamethasone present in each sample or standard. The concentration of Dexamethasone can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
