The genetically modified (GM) crops have been extensively reported in recent years, numerous transgenic products without being labeled as transgenic product have thrown into the market. In this paper, the genomic DNA of corn products was extracted and detected by using modified CTAB and polymerase chain reaction (PCR) methods respectively. Another, corn samples were detected to explore whether or not transgenic ingredients by using specific endogenous gene IVR of the corn as internal parameter, and Cauliflower mosaic virus (CaMV) 35S promoter and nopaline synthase (NOS) terminator as target ge...
