ABSTRACT
This study describes a combination of screening and gene-specific methods for the detection of GMO in food and feed. Using specific primers, the maize ubiquitin promoter and the cryIA(b) gene, which encodes for a delta-endotoxin transferring insect resistance, can be detected simultaneously by a duplex PCR in samples containing the transgenic rice line Kemingdao1 (KMD1). This method is also suitable for the screening for Bt11 maize.
