This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with MT. During the reaction, MT in the sample or standard competes with a fixed amount of MT on the solid phase supporter for sites on the Biotinylated Detection Ab specific to MT. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solut
