摘要：

The time evolution of the fluorescence intensity emitted by well-defined ensembles of green fluorescent proteins has been studied by using a standard confocal microscope. In contrast with previous results obtained in single-molecule experiments, the photobleaching of the ensemble is well described by a model based on Levy statistics. By assuming the presence of thermally activated barriers, this simple model allows us to obtain information about their height distribution.
