| Sumario: | This study outlines the successful development and testing of an immunochromatographic test strip for the detection of the anticoccidial drug, nicarbazin in milk. The preparation and characterization of an anti-4,4′-dinitrocarbanilide monoclonal antibody was based on hapten re-4,4′-dinitrocarbanilide. The monoclonal antibody was highly specific for 4, 4′-dinitrocarbanilide, with a half-life inhibitory concentration (IC50) of 3.46 ng/mL. The detection limit was 0.86 ng/mL. The linear range was 1.71–7 ng/mL. The cut-off values of colloidal gold-based immunochromatographic test paper in phosphate buffered saline (PBS) and in milk were 10 ng/mL, 100 ng/mL, respectively. These results were in good agreement with ELISA analyses and suggest that immunochromatographic test strips are a fast and sensitive method for the semi-quantitative and qualitative analysis of nicarbazin in milk. |
