AHD (Aminohydantoin Hydrochloride) ELISA Kit

AHD (Aminohydantoin Hydrochloride) ELISA Kit About

Test principle

This kit uses Indirect-Competitive-ELISA as the method. It can detect Aminohydantoin hydrochloride (AHD) in samples, such as honey, fish, shrimp, birds, liver and other samples. This kit is composed of Micro ELISA Plate, HRP conjugate, antibody, standard and other supplementary Solutions. The micro-plate provided in this kit has been pre-coated with AHD. During the reaction, AHD in the samples or standard competes with AHD on the solid phase supporter for sites of AHD antibody. Then Horseradish Peroxidase (HRP) conjugate is added to each micro plate well, and TMB substrate is for color development. There is a negative correlation between the OD value of samples and the concentration of AHD. The concentration of AHD in the samples can be calculated by comparing the OD of the samples to the standard curve.
