Single-molecule fluorescence resonance energy transfer
Methods.
2001 Sep.
Abstract
Fluorescent resonance energy transfer (FRET) is a powerful technique for studying conformational distribution and dynamics of biological molecules. Some conformational changes are difficult to synchronize or too rare to detect using ensemble FRET. FRET, detected at the single-molecule level, opens up new opportunities to probe the detailed kinetics of structural changes without the need for synchronization. Here, we discuss practical considerations for its implementation including experimental apparatus, fluorescent probe selection, surface immobilization, single-molecule FRET analysis schemes, and interpretation.
