4. Principle

The Sulfonamides rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. In the flow process, Sulfonamides in the sample combined with Sulfonamides specific colloidal gold-labeled monoclonal antibody, Inhibit the combination between antibody and Sulfonamides-BSA conjugate on Test line of NC membrane, lead to the color change of Test line. When the concentration of Sulfonamides residue in sample is equal to or higher than detection limit, T line has no color, the result is Positive.When the sample has no Sulfonamides residue or concentration lower than detection limit, T line appear, the result is Negative; No matter whether there is Sulfonamides residue in sample, C line will appear, it means the test is valid.
