A general Multiplex-PCR assay for the general detection of Genetically Modified soya and maize

The use of genetically modified organisms (GMOs) as food and in food products is becoming more and more widespread. The European Union has implemented a set of very strict procedures for the approval to grow, import and/or utilize GMOs as food or food ingredients. Thus, analytical methods for the detection of GMOs are necessary in order to verify compliance with labelling requirements. In the past few years, different PCR-based methods for the specific detection of the most economically important GMOs have been proposed. A molecular screening method based on multiplex-PCR that involves amplification of specific soya or maize sequences from plant DNA and the amplification of 35S promoter and NOS terminator for the detection of genetically modified soya and maize was developed. The m-PCR assay discriminated the GMO very quickly, reproducibly and in a cost saving and less time-consuming way. It is a flexible assay to conduce a preliminary GMO screening for detection of genetically modified soya and maize
