The SECM4 is an NIH funded (R24 GM145964) resource to support cryo-EM specimen preparation, screening, data collection, and training to biomolecular researchers primarily in the Southeast. The center is co-located with the Biological Sciences Imaging Resource (BSIR) at Florida State University.  The posts below describe how to access the facility, how to use the instrumentation, and useful protocols for cryo-EM.
