Abstract
This image acquisition protocol is a basic plan for taking a fluorescence lifetime imaging (FLIM) series. FLIM makes live-cell FRET measurements based only on donor fluorescence more feasible, because lifetimes are independent of probe concentration and light path length. The former is not easy to determine in cells, and the latter means that cell shape is not a factor.
