DNA-scaffolded oligodeoxyriboside fluorophores (ODFs) were used as the reporters in turn-on sensing of enzymatic bond-cleaving activity. A tetramer ODF of pyrene deoxynucleosides displayed high quenching efficiency when conjugated via ester linkages with a dabcyl quencher, and yielded large signal increases with several enzymes in vitro and in intact human cells.
DNA支架的寡脱氧核苷荧光团(ODFs)被用作酶切活性开启传感的报告分子。当与dabcyl猝灭剂通过酯键连接时,具有高猝灭效率的四聚体ODF(源于芘的脱氧核苷)在体外和完整的人体细胞中与多种酶反应时产生了显著的信号增加。
