3-NT(3-Nitrotyrosine) ELISA Kit

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with 3-NT. During the reaction, 3-NT in samples or Standard competes with a fixed amount of 3-NT on the solid phase supporter for sites on the Biotinylated Detection Ab specific to 3-NT. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) are added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450 ± 2 nm. The concentration of 3-NT in the samples is then determined by comparing the OD of the samples to the standard curve.
