EPI² Imaging Plateform
The EPI2 imaging platform is part of UMR7216 Epigenetics and Cell Fate centre.
It has several routine epifluorescence microscopes, dedicated to members of the unit, and two cutting-edge pieces of equipment open to external users: a high-throughput Operetta microscope, and a confocal LSM900 microscope equipped with a 266nm UVC laser controlled by a RappOpto module, enabling precise damage of living cells and small organoids by UVC. The optical path of this microscope has been specially adapted for the transmission of the 266nm laser, making this equipment one of the rare ones available in Europe.
If you have any questions about the use of this equipment, please contact the platform managers at epi2imaging@parisepigenetics.com.
