The Danish Cryo-EM Facility - Copenhagen node
The Danish Cryo-EM Facility offers access to state-of-the-art equipment to collect data in single particle and tomography. The Facility has two nodes, one at University at Copenhagen and one at Aarhus University. The Copenhagen node is placed at the Core Facility for Integrated Microscopy (CFIM) at the Faculty of Health and Medial Sciences, and coordinated by CPR and Guillermo Montoya.
The Titan Krios G2 is a powerful and flexible high resolution electron microscope for 3D characterization of biological samples. It was funded by a grant from The Novo Nordisk Foundation and was inaugurated in 2017. You can read more about the instrument at University of Copenhagen here.
The facility is open for all users, access is granted based on applications submitted through the Cryo-EM Application Portal Denmark.
