a 2-nitrobenzyl (NB) protected thiol group have been prepared. The photo-remove of the NB to generate a free thiol group in DNA has been analyzed by using reverse-phase HPLC and denaturing gel electrophoresis. The photo-triggered generation of the thiol function in DNA was applicable in the light-initiated ligation of thiol-modified DNA oligomers and Au–DNA conjugation.
已经制备了具有2-硝基苄基(NB)保护的巯基的DNA低聚物。通过使用反相HPLC和变性凝胶电泳分析了NB的光去除以在DNA中生成游离巯基的现象。光触发DNA中硫醇功能的产生适用于硫醇修饰的DNA低聚物的光引发连接和Au-DNA偶联。
