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