The UW-Madison Cryo-Electron Microscopy Research Center (CEMRC) is a research facility located in the Hector F. DeLuca Biochemical Sciences Complex on the University of Wisconsin-Madison campus. The UW-Madison CEMRC is dedicated to providing instrumentation, technical assistance, training, and access to cryo-EM for the UW-Madison research community. The CEMRC manages and operates four cryo-microscopes for data collection by single particle, tomography, and micro-ED. The microscopes are overseen by experienced staff who offer consultation and training in negative-stain and vitrified sample preparation, single particle analysis, tomography, data processing and additional computational support.

The UW-Madison CEMRC welcomes investigators from other universities and industry.

The UW-Madison Cryo-Electron Microscopy Research Center (CEMRC) is a cross-campus initiative led by a coalition of partners including the Department of Biochemistry, the School of Medicine and Public Health, the Morgridge Institute for Research, the UW Carbone Cancer Center, the Office of the Vice Chancellor for Research and Graduate Education, and the College of Engineering Nanoscale Imaging and Analysis Center.

Any use of the resources in the UW-Madison Cryo-EM Research Center (CEMRC) or the NIH-funded Midwest Center for Cryo-ET (MCCET) requires acknowledgment of use of the resources in presentations and publications as follows:

Standard Acknowledgement:
CEMRC: “Some of this work was performed in the Cryo-EM Research Center (CEMRC) in the Department of Biochemistry at the University of Wisconsin-Madison.”

MCCET: “Some of this work was performed at the Midwest Center for Cryo-ET (MCCET) and the Cryo-EM Research Center located in the Department of Biochemistry at the University of Wisconsin-Madison, supported by the NIH Common Fund Transformative High Resolution Cryo-Electron Microscopy program (U24 GM139168).”

We perform work that is highly collaborative. For each project, our center group members devote significant effort in carrying out the projects at one or more phases in the project pipeline from specimen preparation and data collection to structure interpretation. If your research project involved significant contributions from CEMRC or MCCET staff, please recognize our staff with co-authorship on presentations and publications.
