Many intracellular proteins are catalysts that regulate cellular functions. These catalysts can be assayed to determine their functional state, but untii now it was not possible to simultaneously obtain a functional analysis and spatial data. Tony Ng, Anthony Squire, and others, working in the laboratories of Phillippe Bastiaens and Peter Parker, have combined Fluorescence Lifetime Imaging Microscopy (FLIM) with Fluorescence Resonance Energy Transfer (FRET) to spatially resolve the activation of a protein catalyst within living cells. Their technique was also applied to fixed cells.
