SUD (Sudan I) ELISA Kit (FSES0013)



Technical Manual

SUD (Sudan I) ELISA Kit

Kit Name: SUD (Sudan I) ELISA Kit
Kit Size: 96 Assays
Test Principle: This kit uses Competitive-ELISA as the method. It can detect Sudan I (SUD) in samples, such as tomato juice, chilli sauce, eggs, etc. This kit is composed of ELISA Microtiter plate, HRP conjugate, antibody working solution, standard and other supplementary reagents. The microtiter plate in this kit has been pre-coated with coupled antigen. During the reaction, SUD in the samples or standard competes with coupled antigen on the solid phase supporter for sites of anti-SUD antibody. Then Horseradish Peroxidase (HRP) conjugate is added to each microtiter plate well, and substrate reagent is added for color development. There is a negative correlation between the OD value of samples and the concentration of SUD. The concentration of SUD in the samples can be calculated by comparing the OD of the samples to the standard curve.
