Abstract
We demonstrate the applicability of time-correlated single photon counting multiphoton microscopy to the spatio-temporal localisation of protein-protein interactions in situ. Examples of new fluorescent protein variants with enhanced properties are given and the development of FRET biosensors for simultaneous measurement of multiple intra- and inter-molecular interactions is illustrated by experimental evidence of an energy transfer cascade via multiple acceptors. The juxtaposition of interacting population and FRET efficiency is elucidated, with a priori knowledge, by multi-exponential analysis.
