Since 2016, the Electron Microscopy (EM) facility provides advanced expertise in electron cryomicroscopy, from sample preparation to image analysis, with a focus on single particle analysis.
The equipment is maintained and managed by the facility staff, who also provide training and assistance for anyone wishing to use any of the equipment listed below.
Cryo-EM facilities are available for internal users and on a collaborative basis. Please get in touch with Sarah Schneider to discuss possible access.
120 kV accelerating voltage, LaB6 source. 16M CETA camera, used mainly for negative staining samples, but also capable of cryo-EM using side entry cryo-holders.
200 kV accelerating voltage, field emission gun (X-FEG) source. This microscope is equipped with an autoloader, Falcon 3EC direct detector and is connected to WARP on-the-fly data processing. This microscope is used for cryo-EM sample optimisation and data collection.
Recently, EMBL Grenoble made a special storage system investment to accommodate the ever expanding EM data for the 5 next years. The new system will be run using NetApp technology. This investment will be complemented in 2021 with a high performance storage system that will reduce EM calculation processing time.
The computing cluster shared with the Institut de Biologie Structurale (IBS) allows efficient data processing using state-of-the-art data processing software such as Relion or CryoSPARC. Eight cluster nodes comprising a total of 40 GPUs allow efficient data processing by multiple users. CPU cluster with 600 CPU provides additional resources for other software packages. High-performance computing at EMBL is supported by SBGrid.
