In this study, the event-specific primers for insecticide-resistant maize, MON810, and herbicide-tolerance maize, NK603, have been designed. Simplex PCR and multiplex PCR detection method have been developed. The detection limit of the multiplex PCR is 0.5% for MON810 and NK603 in 50 ng of the template for one reaction. Quantitative methods based on real-time quantitative PCR were developed for...
