Gene sequence detection method

Номер: CN115948511A
Автор: PAN RONGHUI, ZHANG KAI, ZHU XIA, SHEN XINGXING, HU JIN, GUAN YAJING
Принадлежит:

The invention discloses a gene sequence detection method, which is characterized in that a sensor formed by combining electrochemical luminescence with CRISPR/Cas12a changes ECL signal output by introducing a target so as to cause change of energy transfer of an ECL luminescent material on the surface of an electrode. Since the ECL signal is generated without stimulation of an external light source, interference of background signals is reduced while high sensitivity is achieved. The detection system has good stability and repeatability, which are crucial to effective large-scale screening of transgenic crops in regions with relatively deficient resources at present, and we expect that the method may provide a potential platform for detection of transgenic crops.
