Pyrene-modified adenosines in the dangling positions of G-rich oligodeoxynucleotides undergo pi-stacking in their G-quadruplex formation, but not in their single strands, which can be characterized by fluorescence lambda(max) changes that occur on stacking.
在富含鸟嘌呤的寡脱氧核苷酸的悬垂位置上的芘修饰腺苷,在其形成G-四链体时会发生π-堆积,但在单链状态下不会,这可以通过堆积时发生的荧光最大波长变化来表征。
