Gnotobiotic Core

Managed by Animal Care, the gnotobiotic core at Rutgers University provides investigators with the ability to work with germ-free and SPF mice.  Currently the core maintains a germ-free colony with C57BL/6 GF mice.    Our germ-free mice are completely free of exogenous, bacterial, fungal and viral microorganisms. To ensure they remain free of all exogenous microbes, our germ-free mice are housed in isolator cages and are routinely monitored.   These mice are ideal for the study of the microbiome.    The gnotobiotic core also provides investigators with a laboratory that contains a biosafety cabinet and incubator for experimental needs.


We have four Allentown Sealed Positive Pressure racks that house up to 48 cages each. These cages enable a germ-free environment at the cage level. The isolator cages are great for experiments as each cage provides its own individual isolated clean micro-environment.  Each cage has its own supply of clean air which is filtered through a HEPA filter.  The sterility of each cage is tested every two weeks.  We have flexible film isolators available for larger mouse colonies and breeding.
