Single-molecule fluorescence spectroscopy and imaging
Observability of individual fluorescent molecules under a microscope has many applications in biology.1, 2 In particular, by grafting fluorophores to biomolecules, they can be tracked in real time in live cells for monitoring of their conformational changes and interactions with other molecules. In other words, singlemolecule imaging allows scientists to read the textbook of life pretty much as...
متن کاملSingle-Molecule Imaging With One Color Fluorescence.
Single-molecule fluorescence imaging is a powerful tool that enables real-time observation of DNA-protein or RNA-protein interactions with a nanometer precision. Here, we provide a detailed procedure for a previously developed single-molecule fluorescence method, termed "single-molecule protein-induced fluorescence enhancement" (smPIFE). While smFRET (Förster resonance energy transfer) requires...
متن کاملSimultaneous single molecule atomic force and fluorescence lifetime imaging
The combination of atomic force microscopy (AFM) with single-molecule-sensitive confocal fluorescence microscopy enables a fascinating investigation into the structure, dynamics and interactions of single biomolecules or their assemblies. AFM reveals the structure of macromolecular complexes with nanometer resolution, while fluorescence can facilitate the identification of their constituent par...
متن کاملSingle‐Molecule Monitoring of the Structural Switching Dynamics of Nucleic Acids through Controlling Fluorescence Blinking
Single-molecule fluorescence resonance energy transfer (smFRET) is a powerful tool to investigate the dynamics of biomolecular events in real time. However, it requires two fluorophores and can be applied only to dynamics that accompany large changes in distance between the molecules. Herein, we introduce a method for kinetic analysis based on control of fluorescence blinking (KACB), a general ...
متن کاملSnapShot: Single-Molecule Fluorescence
Common uorescent agents include organic uorophores (e.g., Cy5), uorescent proteins (e.g., GFP), and semiconductor quantum dots each with different size, photobleaching, blinking, and labeling ef ciency properties. Wideeld detection with EMCCD camera enables parallel measurements. The temporal resolution is >ms, and the working concentration is limited to nM or less. Confocal detection from an e...
