Description

technical field [0001] The invention belongs to the technical field of biomolecular detection, and in particular relates to a LAMP primer set and a method for detecting transgenic component CaMV35S. Background technique [0002] With the rapid development of genetically modified technology, the industrialization speed of global agricultural biotechnology has also been greatly accelerated, and the promotion and planting area of ​​genetically modified crops has been increasing year by year. A cautious attitude is generally adopted in this regard, and a series of regulations have been introduced to restrict the trade of genetically modified products, requiring the labeling of genetically modified crops and their processed products. Therefore, it is particularly important to establish a sound genetically modified agricultural product and food testing system. [0003] CaMV35S is a common regulatory element for exogenous gene expression in plants and can be used as a marker for t...
