Rapid Visual Identification of Bovine Meat by Loop Mediated Isothermal Amplification Combined with Immunochromatographic Strip

摘要

Considering the factor of culture, religion, health and commerce, the development of a rapid, convenient and sensitive method is important for the detection of the presence of meat species in raw or processed foods. In this study, we employed loop mediated isothermal amplification (LAMP) for species-specific target gene amplification, and the amplicons were analyzed on the immunochromatographic strip (ICS) for the rapid visual identification of meat species. Bovine meat was selected as an example to confirm the performance of such assay. The LAMP based ICS method show good specificity, repeatability and has a limit of detection of 0.1% for beef in meat mixture. The whole detection process could be completed within 50 min. Our method: is more convenient,and rapid compared to classicaqAMP. Moreover, it could be, easily adapted to identify types of meats, and it may be useful for food administration laboratories to carry out meat species identification idiaw. and processed foods.
