Abstract

Abstract: The DNA G-quadruplex formed by the human telomeric sequence is a potential target for novel anticancer drugs. We have investigated an intramolecular DNA G-quadruplex using single-molecule fluorescence resonance energy transfer and shown that individual folded quadruplexes can be identified. The mean proximity ratio measured at the single-molecule level was consistent with ensemble measurement.

Key words: G-quadruplex, Fluorescence resonance energy transfer(FRET), Single-molecule spectroscopy
