The Electron Microscopy department of the PICsL Imaging facility provides the scientific community with 1. the expertise, 2. the material and 3. electron microscopes necessary for molecular, cellular and tissue-level imaging by electron microscopy.
Our service offer comprises the sample preparation with the following methods: negative staining, plastic embedding, immuno-labelling, high pressure freezing, freeze substitution, (cryo)-ultramictotomy…
We routinely use advanced imaging modes such as electron tomography (ET), cryo-Electron Microscopy (cryo-EM), Scanning Transmission Electron Microscopy (STEM), Scanning Electron Microscopy in « Serial Block-Face » mode (see an example above), Correlative Light and Electron Microscopy (CLEM)…
For the users willing to work autonomously, we offer individual or group trainings for the conventional methods in transmission and scanning electron microscopy.

Transmission Electron
Microscope FEI Tecnai G2 200 kV.
This microscope is designed for advanced imaging modes such as electron tomography, STEM and cryo-electron microscopy. With its 200kV gun and the optical quality of its column, it can reach a magnification of about 200 000x. It is equipped with an Olympus Veleta 2k camera and an FEI Eagle 4k camera.
This microscope has been co-funded by the Plan Cancer, the INSB, the FEDER and the IBDM.
Scanning Electron
Microscope FEI Teneo VS.
With this microscope, our users can aqcuire conventional MEB images of an outstanding quality. Moreover, this microscope is equipped with an automatized ultra-microtomy module. By the technique of Serial Block-Face, the microscope autonomously alternate between cutting and imaging steps of an embedded sample. With a rate of one image per minute, this microscope is a revolution in the field of 3D electron microscopy. For instance, given a field of view of 40µm width and a pixel size of 5x5x40 nm, the microscope can image 20µm in depth within the sample in an overnight acquisition.
This microscope has been co-funded by the Bettencourt Schueller Society, the GIS IBISA, the Labex INFORM, the PACA area, Aix-Marseille University and the Plan Cancer.
Transmission Electron
Microscope FEI Morgagni 120 kV.
This microscope enables the insertion of samples in less than 20 seconds. It is therefore very useful for grids quality checks. It is equipped with a camera and can be used to acquire images up to a 20 000x magnification.
