Correcting confocal acquisition to optimize imaging of fluorescence resonance energy transfer by sensitized emission.
Imaging of fluorescence resonance energy transfer (FRET) between suitable fluorophores is increasingly being used to study cellular processes with high spatiotemporal resolution. The genetically encoded Cyan (CFP) and Yellow (YFP) variants of Green Fluorescent Protein have become the most popular donor and acceptor pair in cell biology. FRET between these fluorophores can be imaged by detecting...
متن کاملA quantitative protocol for intensity-based live cell FRET imaging.
Förster resonance energy transfer (FRET) has become one of the most ubiquitous and powerful methods to quantify protein interactions in molecular biology. FRET refers to the sensitization of an acceptor molecule through transfer of energy from a nearby donor, and it can occur if the emission band of the donor exhibits spectral overlap with the absorption band of the acceptor molecule. Numerous ...
متن کاملBreakthrough Technologies Combined Bimolecular Fluorescence Complementation and Förster Resonance Energy Transfer Reveals Ternary SNARE Complex Formation in Living Plant Cells
Various fluorophore-based microscopic methods, comprising Förster resonance energy transfer (FRET) and bimolecular fluorescence complementation (BiFC), are suitable to study pairwise interactions of proteins in living cells. The analysis of interactions between more than two protein partners using these methods, however, remains difficult. In this study, we report the successful application of ...
متن کاملQuantification of Förster resonance energy transfer by monitoring sensitized emission in living plant cells
Förster resonance energy transfer (FRET) describes excitation energy exchange between two adjacent molecules typically in distances ranging from 2 to 10 nm. The process depends on dipole-dipole coupling of the molecules and its probability of occurrence cannot be proven directly. Mostly, fluorescence is employed for quantification as it represents a concurring process of relaxation of the excit...
متن کاملFluorescence resonance energy transfer detection methods: Sensitized emission and acceptor bleaching
The present study compared the advantages and disadvantages of fluorescence resonance energy transfer (FRET) determination technologies, namely, sensitized emission (SE) and acceptor bleaching (AB), in order to analyze the applicability of SE and AB for studies investigating particularly interesting new cysteine histidine-rich protein 1 (PINCH1)/integrin-linked kinase (ILK) interaction. HeLa ce...
