A sensitive and selective assay of uracil DNA glycosylase (UDG) activity is developed by utilizing a G-quadruplex probe incorporating 2-aminopurine (2-AP), based on a novel design that excision reaction promoted by UDG triggers the formation of G-quadruplex structure with significant fluorescence enhancement of 2-AP within the probe.
通过利用一种掺入2-氨基嘌呤(2-AP)的G-四链体探针,开发了一种灵敏且选择性的尿嘧啶DNA糖基化酶(UDG)活性检测方法,该方法基于一种新颖的设计,即UDG促进的切除反应触发G-四链体结构的形成,同时探针内的2-AP荧光显著增强。
