Principiul testului

Vanillylmandelic Acid ELISA Kit (A326990) employs the competitive enzyme immunoassay technique for the quantitative measurement of Vanillylmandelic Acid in serum, plasma, and other biological fluids. The 96-well microtiter plate has been pre-coated with Vanillylmandelic Acid antigen. During the incubation, Vanillylmandelic Acid present in the samples or standards competes with the fixed amount of immobilized Vanillylmandelic Acid for binding sites on the Biotinylated Anti-Vanillylmandelic Acid Antibody. The more Vanillylmandelic Acid present in a sample or standard, the less Biotinylated Anti-Vanillylmandelic Acid Antibody that binds to the plate. Following incubation, unbound Biotinylated Anti-Vanillylmandelic Acid Antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. 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 Vanillylmandelic Acid present in each sample or standard. The concentration of Vanillylmandelic Acid can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
