Epifluorescence Microscopy
The platform has two widefield microscopes for the acquisition of material fixed in fluorescence, a widefield microscope equipped with a colour camera, a routine fluorescence microscope for the observation of living cells and an analysis computer equipped with Fiji and Icy software. This equipment is reserved for the internal use of UMR7216 members.
