Determination of association constants and FRET in hydrazide-based molecular duplex strands

Abstract

FRET pair pyrene and perylene fluorophores were incorporated into hydrazide-based molecular duplex strands. The dimerization constants were determined via monitoring the pyrene excimer emission band. When non-fluorescent hydrazide-based oligomers with...
