      Test principle

      This kit uses Indirect-Competitive-ELISA as the method. It can detect SEM in samples, such as honey, tissue, milk, fodder, etc. This kit is composed of MicroELISA Plate, HRP conjugate, antibody, standard and other supplementary reagents. The micro-plate provided in this kit has been pre-coated with SEM. During the reaction, SEM in the samples or standard competes with SEM on the solid phase supporter for sites of SEM 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 SEM. The concentration of SEM in the samples can be calculated by comparing the OD of the samples to the standard curve.
