Seeing red: DEAB‐TO‐3 shows a large fluorescence enhancement upon binding to native DNA and a distinct selectivity for double‐stranded DNA over total RNA. As a red fluorescent live‐cell‐permeant DNA minor groove binder, DEAB‐TO‐3 is promising for highly sensitive DNA detection in vitro and nucleus‐specific imaging and DNA quantification in vivo (see picture).
看到红色:DEAB-TO-3在与天然DNA结合后显示出很大的荧光增强,并且对双链DNA的选择性超过总RNA。作为红色荧光活细胞渗透性DNA小沟结合剂,DEAB‐TO-3有望在体外进行高灵敏度的DNA检测,并在体内进行核特异性成像和DNA定量(见图)。
