Abstract
A rapid immunochromatographic lateral flow test strip of competitive format has been developed for the specific determination of olaquindox (OLA) residues in pig urine and muscle tissues. The sensitivity of the test strip was found to be 1.58 ± 0.27 μg/kg and 1.70 ± 0.26 μg/kg of OLA in pig urine and muscle tissues, and the lower detection limit was 0.27 ± 0.08 μg/kg and 0.31 ± 0.07 μg/kg respectively. For negative pig urine and muscle samples spiked with 4, 12, and 36 μg/kg, the recovery range was 83.0-94.0% and 78.8-87.4% and the coefficient of variation scope [CV (%)] was 3.17-7.41% and 4.66-7.64% respectively. Parallel analysis of OLA samples from pig urine and muscle tissue showed comparable results from the test strip and HPLC. Each test requires 5-8 min, and the test strip can provide a useful screening method for quantitative, semiquantitative, or qualitative detection of OLA residues.Entities:
