Establishment of a Method to Detect Genetically Modified Plant FMV35S Promoter in Food and Feeds Using Loop-mediated Isothermal Amplification

Objective] To establish a method to detect genetically modified plant FMV35S promoter in food and feeds using loop-mediated isothermal amplification.Method] A method was established to detect FMV35S gene in food and feed using loop-mediated isothermal amplification （LAMP）.The stability,specificity and sensitivity of the LAMP assay was evaluate by real-time turbidity method.Result] The results showed that the concentration which LAMP assay can detect is as low as 0.5％ （W/W）,and the stability and specificity of the test is satisfied.Conclusion] Comparing with the testing results between the real-time methods and LAMP method,it is confirmed that the method could be used to analyze FMV35S genetically modified ingredients in food or feed.
