Principiul testului

Nitrofurans ELISA Test Kit (A327230) employs the competitive enzyme immunoassay technique for the quantitative measurement of Nitrofurans in fish, shrimp, meat (chicken, pork and hepar), eggs, honey, milk, feed. The 96-well microtiter plate has been pre-coated with Nitrofurans. During the incubation, Nitrofurans present in the samples or standards competes with the fixed amount of immobilized Nitrofurans for binding sites of the Anti-Nitrofurans Antibody, a HRP-Conjugated Secondary Antibody is added to the wells at the same time. The more Nitrofurans present in a sample or standard, the less Anti-Nitrofurans 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 Nitrofurans present in each sample or standard. The concentration of Nitrofurans can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
