Nitrofuran(SEM) Rapid Test Strip (Tissue, honey, egg)

Principle

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