Donor (D) and acceptor (A) molecule which participate in FRET (Förster resonance energy transfer).

What is FRET with FLIM (FLIM-FRET)?

This article explains the FLIM-FRET method which combines resonance energy transfer and fluorescence lifetime imaging to study protein-protein interactions.

Step by Step Guide for FRAP Experiments

Fluorescence Recovery After Photobleaching (FRAP) has been considered the most widely applied method for observing translational diffusion processes of macromolecules. The resulting information can be…

Fluorescence Correlation Spectroscopy (FCS)

Fluorescence correlation spectroscopy ( FCS ) measures fluctuations of fluorescence intensity in a sub-femtolitre volume to detect such parameters as the diffusion time, number of molecules or dark…

Fluorescence Recovery after Photobleaching (FRAP) and its Offspring

FRAP (Fluorescence recovery after photobleaching) can be used to study cellular protein dynamics: For visualization the protein of interest is fused to a fluorescent protein or a fluorescent dye. A…

Förster Resonance Energy Transfer (FRET)

The Förster Resonance Energy Transfer (FRET) phenomenon offers techniques that allow studies of interactions in dimensions below the optical resolution limit. FRET describes the transfer of the energy…
