Rapid detection of triadimefon residues in tobacco leaves with colloidal gold immunochromatography
摘要
Abstract
Gold immunochromatography assay was adopted to establish a rapid detection method for triadimefon residues in tobacco leaves.Colloidal gold was prepared by sodium citrate method,and was then conjugated to triadimefon antibodies.Triadimefon-OVA and anti-mouse goat immunoglobulins were jet-positioned onto a nitrocellulose membrane.Sample pad,gold jed pad,nitrocellulose membrane and absorbent paper were assembled and cut into detecting card,respectively.Results showed that the sensitivity of rapid triadimefon visual detection limit is 1 mg/kg for residues of triadimefon and triadimenol in tobacco leaves,and detection time was 5~10 min.Repeatability was good,and it gave almost no false positive or negative results compared with gas chromatography-tandem mass spectrometry.关键词
