Correlative Light Microscopy Dutch Flagship Node

The Dutch Correlative Light Electron Microscopy flagship Node is a consortium of the 4 most prominent correlative LM-EM (CLEM) labs in the Netherlands, headed by Klumperman (Utrecht), Gerritsen (Utrecht), Koster (Leiden) and Giepmans (Groningen). All labs have an international track record in microscopy technique development, application, training and open access and are at the forefront of CLEM.

Specialties and expertise of the Node

Making use of the complementary specialties of the participating labs, collectively the Node provides a unique package of CLEM methods for open access. These include state-of-the-art techniques to correlate live-cell imaging and a variety of room temperature and cryo-fluorescence microscopy techniques with immuno-EM of ultrathin cryosections, cryo-EM, 3D electron tomography and FIB-SEM. Also we can prepare samples imaged by LM in the home lab for subsequent EM analyses in our Node.

Instrument highlights

The Dutch CLEM Node contains the full set of equipment to allow CLEM experiments from light or live cell imaging to biological sample preparation to EM analysis. Specialized equipment includes cryomicrotomes, cryo-EM, iCLEM and FIB-SEM. Specific CLEM techniques include correlative light - immuno-electron microscopy on ultrathin cryosections (Tokuyasu technique), correlative live cell – 3D electron microscopy, cryo-CLEM and large volume CLEM.
