Abstract

The dynamic and static properties of the fluorescence of a pyrene-introduced oligonucleotide 16 mer and its hybrid with a target 32 mer. Their fluorescence quantum yields (< 1%) were much weaker than that of unsubstituted pyrene and their fluorescence lifetime of the major decay components were less than 1 ns. The rapid fluorescence quenching was due to the interaction between the fluorophore and bases in the oligonucleotides. The fluorescence of pyrene was quenched efficiently by TMP and slightly by AMP. The quenching by CMP and GMP were the intermediate case.

附在寡核苷酸杂交探针上的芘残基的荧光特性动力学。
芘引入寡核苷酸16聚体及其与靶32聚体杂合体的动态和静态荧光性质。它们的荧光量子产率(< 1%)比未取代芘弱得多,其主要衰变组分的荧光寿命小于1 ns。荧光猝灭是由于荧光团与寡核苷酸中的碱基相互作用所致。芘的荧光被TMP有效猝灭,被AMP轻微猝灭,CMP和GMP是中间猝灭情况。
