Authors: Eaazhisai Kandiah / Thierry Giraud / Alejandro de Maria Antolinos / Fabien Dobias / Gregory Effantin / David Flot / Michael Hons / Guy Schoehn / Jean Susini / Olof Svensson / Gordon A ...Authors: Eaazhisai Kandiah / Thierry Giraud / Alejandro de Maria Antolinos / Fabien Dobias / Gregory Effantin / David Flot / Michael Hons / Guy Schoehn / Jean Susini / Olof Svensson / Gordon A Leonard / Christoph Mueller-Dieckmann / Abstract: Recent improvements in direct electron detectors, microscope technology and software provided the stimulus for a `quantum leap' in the application of cryo-electron microscopy in structural biology, ...Recent improvements in direct electron detectors, microscope technology and software provided the stimulus for a `quantum leap' in the application of cryo-electron microscopy in structural biology, and many national and international centres have since been created in order to exploit this. Here, a new facility for cryo-electron microscopy focused on single-particle reconstruction of biological macromolecules that has been commissioned at the European Synchrotron Radiation Facility (ESRF) is presented. The facility is operated by a consortium of institutes co-located on the European Photon and Neutron Campus and is managed in a similar fashion to a synchrotron X-ray beamline. It has been open to the ESRF structural biology user community since November 2017 and will remain open during the 2019 ESRF-EBS shutdown. | |||||||||
