QuicKey Pro Rat CORT (Corticosterone) ELISA Kit, 96T

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Rat Cort. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Rat Cort are added to the micro ELISA plate wells. Rat Cort in samples (or standards) competes with a fixed amount of Cort on the solid phase supporter for sites on the HRP linked detection antibody specific to Cort. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The concentration of Rat Cort in the samples is then determined by comparing the OD of the samples to the standard curve.
