Single-molecule fluorescence spectroscopy reveals the real time dynamics that occur during biomolecular interactions that would otherwise be hidden by the ensemble average. It also removes the requirement to synchronize reactions, thus providing a very intuitive approach to study kinetics of biological systems. Surface immobilization is commonly used to increase observation times to the minute time...
Single-molecule fluorescence resonance energy transfer (smFRET) microscopy has become an increasingly popular tool to study the structural dynamics of RNA molecules. It reveals, in real time, the structural dynamics of these molecules that would be otherwise hidden in ensemble-averaged measurements. Here we present a detailed protocol for performing smFRET using total internal reflection fluorescence...
