What Does FRET Stand For?

FRET stands for Fluorescence Resonance Energy Transfer

Fluorescence Resonance Energy Transfer (FRET) is a biophysical technique used to measure distances between specific molecules, typically in the range of 1 to 10 nanometers. It involves the non-radiative transfer of energy from a donor fluorescent molecule to an acceptor molecule when they are in close proximity. FRET is widely utilized in molecular biology and biochemistry to study protein interactions, conformational changes, and cellular processes, providing insights into dynamic biological systems at the molecular level.
