National Cryo-EM centers

NIH has established three national cryo-EM service centers to provide access to the technology and is supporting the development of cryo-EM training curricula to build a skilled workforce.
All three have started to accept external proposals to use their existing resources. A key feature of these centers is that the access (including training) is proposal-based and free of charge. 
In addition, NCI provides access to Titan Krios to projects that are relevant in cancer research.
