Simultaneous Screening for Five Veterinary Drug Residues by a Developed Multiplexed Luminex Assay

The development of sensitive and rapid methods for simultaneous determination of multiple residual veterinary drugs in foods is increasingly important. In this study we reported a new method to simultaneously detect five veterinary drug residues, including ractopamine, clenbuterol, furazolidone, chlortetracycline and qlaquindox. The experimental results indicated that the developed multiplex assay enable to detect all the five drugs at the concentration of 0.1 ng/mL, with desirable specificity, suggesting that it could be applicable for rapid screening of five residual veterinary drugs in a faster turnaround time and higher throughput.
