Detection of veterinary drug resi- dues are extremely important practical significance to protect the ecological environment and human health. In recent years, liquid chromatography -tandem mass spectrometry has been widely used in vetednary drug residue detection because of its applicability, qualitative and quantitative fea- tures as well as high sensitivity. This article summarized the application of liquid chromatography -tandem mass spectrometry in detection veterinary drug residues from feed, animal products, arid udne as well as illicit drugs and harmful additives.展开更多

[ Method ] A total of six special primers were designed based on the conserved sequences of CSFV gene. After optimizing, the reaction of RT-LAMP was carded out at 63℃ for 45 rain. The RT-LAMP products were analyzed by agarose gel electro- phoresis. The sensitivity, specificity and repeatability were verified, respectively. [ Result] The RT-LAMP method could be used for detecting CSFV rather than six generic viruses. The sensitivity of RT-LAMP was 100 times higher than that of RT-PCR. The detection of 27 clinical samples by RT- LAMP and RT-PCR showed that RT-LAMP is more reliable and convenient. [ Conclusion] The RT-LAMP method is sensitive and reliable for the detection of CSFV.展开更多
