Description
Principle of the Assay: This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with Prl3b1. During the reaction, Prl3b1 in the sample or standard competes with a fixed amount of Prl3b1 on the solid phase supporter for sites on the Biotinylated Detection Antibody specific to Prl3b1. Excess conjugate and unbound sample or standard are washed from the plate, and HRP-Streptavidin(SABC) is 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 a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of Prl3b1 in the samples is then determined by comparing the O.D. of the samples to the standard curve
