This ELISA kit applies to the in vitro quantitative determination of ACH concentrations in serum, plasma and other biological fluids.This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with ACH. During the reaction, ACH in the sample or standard competes with a fixed amount of ACH on the solid phase supporter for sites on the Biotinylated Detection Ab specific to ACH. Excess conjugate and unbound sample or standard are washed from th
