Research output: Contribution to journalConference article


FRET measurements were performed on cell surface receptors, where the distances are constant, and the only changing parameter is the donor-acceptor ratio of the used labels. The FRET efficiencies were measured either in a microscope using the photobleaching method or in a fluorescence activated cell sorter (FACS). There was a marked difference between the FRET efficiencies measured by flow cyclometry and with the photobleaching method (pbFRET) even on same cells and between same epitopes.
