Visualizing Intracellular SNARE Trafficking by Fluorescence Lifetime Imaging Microscopy

Abstract:
The recent development of Förster resonance energy transfer (FRET) sensors and FRET imaging techniques permits visualization of the dynamics of intracellular signaling events with high spatiotemporal resolution. In particular, fluorescence lifetime imaging in combination with two-photon laser-scanning microscopy (two-photon fluorescence lifetime imaging microscopy [2pFLIM]) is a powerful tool to monitor signaling events in small subcellular compartments in thick tissue. This article provides practical guidelines for quantitative imaging of intracellular signaling using 2pFLIM.

Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
