Abstract

The invention relates to a rape transgenosis detecting kit in the field of detecting articles. The rapeseed transgenosis detecting kit comprises a primer combination and a membrane chip, and is characterized in that the primer combination is a 11-double-starting oligonucleotide primer combination, the membrane chip refers to 11 groups of probe sequences and one group of positive control probe sequences, which are fixed on the surface of a supporting film, and the 5' end of each probe is provided with an amino marker; asymmetric PCR (polymerase chain reaction) amplification primers, which are Tag primers with biotin marks at 5'ends, are included in the primer combination. The rapeseed transgenosis detecting kit provided by the invention overcomes the defects of time and energy waste and high cost in the prior art, the rape transgenosis detecting kit provided is simple to operate, is quick and sensitive, is high in detection flux, has visual detection results and is low in cost.

Description

Technical field [0001] The invention relates to the field of detection supplies, in particular to a rapeseed transgene detection kit. Background technique [0002] Rapeseed is a Brassica plant in the family Brassicaceae, and it is the earliest and most widely studied crop in the study of transgenic crops. In 1985, Ooms et al. used the Agrobacterium-mediated method to successfully cultivate the first transgenic Brassica napus. Since then, major multinational companies have bred a variety of transgenic rapeseed strains, and after 1995, they have passed biosafety assessments in North America, Japan and other places and approved commercial planting. As of 2010, the planting area of ​​transgenic rapeseed in the world has exceeded 7 million hectares 2 , accounting for 23% of the total planting area of ​​rapeseed in the world, ranking fourth in the world after genetically modified soybeans, corn, and cotton. Rapeseed is an important oil crop, and more than half of my country's c...
