Bind it! A ratiometric fluorescent probe based on conjugation of a DNA‐binding ligand with an environmentally sensitive dye to probe hydrophobic grooves of the DNA helix was developed. The resulting conjugate ATMND–DBD can bind to an orphan nucleobase opposite an abasic (AP) site with high selectivity and affinity for pyrimidine bases (see figure).
绑定!基于DNA结合配体与对环境敏感的染料缀合以探测DNA螺旋的疏水沟的比例荧光探针被开发出来。产生的共轭物ATMND–DBD可以与对无碱基(AP)位点相对的孤核碱基结合,对嘧啶碱基具有很高的选择性和亲和力(见图)。
