Abstract: To establish a rapid assay for detecting fluoroquinolones in milk, gold immunochromatography assay was studied, which was used with a readout instrument of colloidal gold test paper card together. The limit of detection(enrofloxacin, sarafloxaxcin, difloxacin, ofloxacin, norfloxacin, ciprofloxacin, pefloxacin, flumequine, danofloxacin)is 20 μg/L, and(enoxacin, oxolinic acid)is 40 μg/L. We can obtain the results in 10 minutes. The assay gives no false positive and false negative results. The method is accurate, simple, reliable and convenient to rapidly detect fluoroquinolones of a lot of samples on the spot.
