Cellular imaging by electron microscopy


Different techniques are available in the platform to allow the observation of biological samples

1. Fixation

  • Chemical fixation
  • Fixation by high-pressure freezing

2. Inclusion

  • Classical embedding (EPON, LR White)
  • Cryo-substitution and embedding

3. Sectioning

  • Classical sectioning
  • Cryo-sectioning (Tokuyasu)

4. Labeling and Staining

  • Post-staining
  • Immunolabeling (manual or automated)

5. Observation

  • Trasmission Electron Microscopy


Cellular Transmission Electron Microscopy, High-Pressure Freezing, cryo-substitution, ultra-thin sections, immuno-labeling.

Sample types

Cell monolayer or pellet, bacteria, or tissue.
Samples have to be at the biohazard level L1.
L2 samples must be chemically fixed before.


The results allow:

  • Morphological studies of cells and bacteria
  • Protein localization at a sub-cellular level
  • Determination of virus infection cycle

Development of correlative microscopy is in progress.

Data Storage

Data are stored for 3 years.
