A termini-free molecular beacon type of DNA bearing a novel silylated perylene and an anthraquinone both at the C-5 position of deoxyuridine residues exhibits prominent fluorescence upon mixing with complementary oligonucleotide (24- to 50-fold increase in comparison with a single-stranded state) along with one base mismatch discrimination ability.
在脱氧尿苷残基的 C-5 位上含有一种新型硅烷化亚甲基和一种蒽醌的无末端分子信标型 DNA 与互补寡核苷酸混合后会发出明显的荧光(与单链状态相比,荧光增加了 24 至 50 倍),并具有一个碱基错配的识别能力。
