FRET by photobleaching of the acceptor. Upon photobleaching of Cx43-YFP (right), the intensity of Cx43-CFP increases (left).

Zeiss Confocal microscope LSM 780

Laser scanning confocal microscopy has become the golden standard in imaging biological samples, allowing for good resolution and flexibility in stainings. 

LSM780 is an inverted laser scanning confocal microscope equipped for live imaging (temperature and CO2 control). It has a tunable laser giving it a high flexibility in fluorophore excitation. The GaASP detector allows for detection of faint stainings and spectral imaging (separation of spectrally overlapping fluorophores).
