Abstract

The invention discloses a kit for detecting genetically modified soybean in the field of test items. The kit for detecting genetically modified soybean comprises a primer combination and a membrane chip. The kit for detecting genetically modified soybean is characterized in that the primer combination is a seven polymerase chain reaction (PCR) primer combinations; each pair of primers comprise Pat, Bar, Cry1Ab, Cry105, EPSPS, P35S and a soybean endogenous gene sequence Lectin; the membrane chip is seven groups of probe sequences, which are orderly fixed on the surface of a support membrane and a group of positive control probe sequences, the probe sequences are respectively a Pat probe, a Bar probe, a Cry1Ab probe, a Cry105 probe, an EPSPS probe, a P35S probe, a Lectin probe and a Positive probe; an asymmetric PCR amplification primer is formed in the primer combination, and is a Tag primer with a biotin marker (biotin) at the 5' end. By adopting the kit for detecting genetically modified soybean, the defects of time and labor waste, and high cost in the prior art are overcome; the provided kit for detecting genetically modified soybean is simple to operate, quick and sensitive, large in detection throughput, visual in detection result and low in cost.

Description

Technical field [0001] The invention relates to the field of detection supplies, in particular to a soybean transgene detection kit. Background technique [0002] Genetically modified corn and genetically modified soybeans are currently the most important genetically modified food crops in the world. Genetically modified soybeans are the earliest commercially planted and fastest-growing genetically modified food crops. Since it was approved for commercial production in 1996, as of 2008, the planting area has reached 65.8 million hectares, accounting for 69% of the global soybean planting area and 53% of the global genetically modified crops. Due to the massive emergence of genetically modified products in the global market, their environmental and food safety issues have also attracted international attention. Various countries have successively formulated and promulgated corresponding laws and regulations, and adopted strict management measures for the environmental relea...
