Abstract:
This is a short account of fluorescence lifetime-resolved imaging, in order to acquaint readers who are not experts with the basic methods for measuring lifetime-resolved signals throughout an image. We present the early FLI (fluorescence lifetime imaging) history, review shortly the instrumentation and experimental design, discuss briefly the fundamentals of the measured fluorescence response, and introduce the basic measurement methodologies. We also emphasize the complex nature of the fluorescence response in FLI signals, and introduce certain analysis methods that are appropriate and informative for complex fluorescence decays. The advantages of model independent analyses are discussed and examples given.

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...
