Abstract

The invention discloses primer groups, a kit and a method for detecting a specific sequence of a glyphosate-resistant transgenic soybean transformant. Two groups of LAMP (loop-mediated isothermal amplification) primers are designed, the primer group 1 is used for detecting an internal reference gene Lectin and can detect soybean ingredients in a sample and simultaneously exclude false negative results, and the primer group 2 is used for detecting the specific sequence of the glyphosate-resistant transgenic soybean transformant, has high specificity and can effectively detect glyphosate-resistant transgenic soybean ingredients, wherein the sequence is a boundary sequence which connects an inserted exogenous gene with a plant gene. When the kit is used for the detection and analysis of a sample, a positive control, a blank control and an internal control are respectively set, so that the production of false positives and false negatives can be avoided. Special equipment is not required for detection, and the detection cost is low; and the detection results can be judged by visual observation of changes in color of a reaction solution, the identification is simple and convenient to perform, the results are visualized, and the primer groups, the kit and the method disclosed by the invention are suitable for field fast detection and grassroots screening of a large number of samples and easy to realize large-range popularization and application.

Description

technical field

[0001] The invention belongs to the field of biological detection, and in particular relates to a primer set, a kit and a method for detecting the specific sequence of a glyphosate-resistant transgenic soybean transformant. Background technique

[0002] With the rapid development of genetically modified organisms, their safety has aroused intense debate and widespread concern around the world. In order to protect consumers' right to know and right to choose, many countries and regions in the world have enacted corresponding laws and regulations to strengthen the management of import and export of genetically modified products, which brings new challenges to the genetically modified testing work that provides technical support for the safety supervision of genetically modified organisms. Come to greater challenges. There are many methods for detecting genetically modified products, which are mainly divided into two categories: detection of exogenous proteins ...
