This ELISA kit applies to the in vitro quantitative determination of Mouse u-T4 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 u-T4. During the reaction, u-T4 in the sample or standard competes with a fixed amount of u-T4 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to u-T4. Excess conjugate and unbound sample or standard are was
