FRET microscopy
Also known as: Förster resonance energy transfer microscopy, FRET imaging
Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Imaging molecular interactions in living cells by FRET microscopy. FRET imaging provides information about all these molecular processes with high specificity and sensitivity via probes expressed by or introduced from the external medium into the cell, tissue or organism.
Usefulness & Problems
Why this is useful
FRET microscopy images molecular interactions and structural changes in living cells by reporting distance-dependent energy transfer between probes. The review frames it as a nanoruler operating over intramolecular and intermolecular distance scales relevant to cellular regulation.; imaging molecular interactions in living cells; measuring intramolecular and intermolecular distances at nanometer scale; monitoring binding, conformational transition, covalent modification, and transport
