The Gnotobiotic Animal Core (GNAC) at the University of Washington (UW) is a core facility started in 2014 and managed by the Department of Comparative Medicine.  Located in the UW Health Sciences Center, the GNAC is open to investigators with research needs to maintain mice free of any microorganisms (germ-free), or with a known population of microorganisms (gnotobiotic).


Our facility is available to all University of Washington investigators and outside institutions.

For more information, please contact co-directors Lynn Hajjar or Charlie Hsu.
