title: Probing the stable G-quadruplex transition using quencher-free end-stacking ethynyl pyrene-adenosine.
abstract: 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.
