Abstract

The invention discloses a method for detecting transgenic components of corn by utilizing quadruple real-time fluorescent PCR, and primers and probes used in the method. The method disclosed by the invention comprises the following steps of designing the primers and the probes required by quadruple real-time fluorescent PCR amplification; extracting genome DNA in the corn to be detected; carryingout quadruple real-time fluorescent PCR amplification; and judging whether the corn to be detected is transgenic corn or not according to a PCR amplification result. The invention provides the effective method for rapidly detecting whether the corn and a deep processing product thereof are the transgenic corn or not.

Description

technical field

[0001] The invention relates to transgenic corn and its deep-processed products, in particular to a quadruple real-time fluorescent PCR detection method applicable to whether the corn and its deep-processed products contain genetically modified ingredients (that is, whether it is genetically modified corn), and belongs to the field of food safety transgenic detection. Background technique

[0002] Corn is the second largest commercial food crop in the world. The global planting area is about 60.6 million hectares, accounting for 45.1% of the global transgenic planting area. The transgenic penetration rate has reached 33%, making it the second largest crop in planting area. At present, there are 146 lines of genetically modified corn in the world, mainly including genetically modified traits such as herbicide resistance, insect resistance, quality improvement, drought tolerance, insect resistance + herbicide tolerance, quality and herbicide tolerance. As a maj...
