Animal Facility


The Animal Facility Shared Resource facilitates research through humane and efficient management of animal populations. The vivarium operates as a modified barrier facility and is equipped with quarantine and a procedure room, holding rooms with biosafety cabinets, an imaging/holding room equipped with a PerkinElmer IVIS SpectrumCT imaging system, SonoVol Vega ultrasound system and additional support areas. The Facility has rack space for more than 6,000 sterile, disposable, and individually ventilated mouse cages. Space for housing limited numbers of small animal species other than mice is also available upon request. Wistar’s Animal Care and Use Program, overseen by The Wistar Institutional Animal Care and Use Committee (IACUC), is fully accredited by AAALAC International since 1998, has an assurance on file with the Office of Laboratory Animal Welfare at the NIH, and is a registered USDA research institution.
