Abstract
This invention discloses a test strip for detecting thiophanate-methyl and its application. The test strip includes a sample absorption pad (1), a conjugate release pad (2), a reaction membrane (3), an absorbent pad (4), and a base plate (7). The reaction membrane has a detection line (5) coated with a thiophanate-methyl hapten-carrier protein conjugate and a control line (6) coated with goat anti-mouse anti-antibody. The conjugate release pad (2) is coated with a thiophanate-methyl monoclonal antibody-colloidal gold label. This invention also provides a method for detecting thiophanate-methyl residues in vegetables and fruits using the above-mentioned thiophanate-methyl test strip. The test strip provided by this invention has the characteristics of simple operation, high sensitivity, fast detection speed, and low cost, and is suitable for screening large numbers of samples and on-site monitoring.
