Breeding Colony

Breeding Colony Manager holds guinea pigAlthough genetically engineered mice (GEM) are available from commercial vendors, including Jackson Laboratory, Charles River, and ENVIGO, many U-M investigators require additional assistance to maintain their breeding colonies on campus.

The Unit for Laboratory Animal Medicine (ULAM) Breeding Colony provides administrative, technical, and husbandry services to investigators who do not have the time, facilities, or resources to manage their own breeding colony.

The Breeding Colony currently supports 70 investigators and manages over 350 various strains of genetically engineered and severe combined immuno deficient (SCID) mice. Users must have an approved animal use protocol from the Institutional Animal Care & Use Committee (IACUC) prior to utilizing Breeding Colony services.
