Animal Aging

While mice ship at 12 weeks of age, we are happy to meet your needs for custom or standard animals at whatever age you need. Our expert Colony Management Solutions team is ready to work with you to develop an appropriate plan for generating the research animals for your study.
If you are using B6 mice, then we have a ready stock available:
B6 Males:
  • Readily available up to one year of age
  • Possibly available over one year of age—call for inventory
  • Males are reduced-density virgin cagemate, not retired breeders
Retired breeders available for most live models:
Limited quantities of retired breeders are available for most commercial models. They may provide a quick option to perform a pilot study with aged animals. Retired breeders are typically 6-9 months of age, but may be younger. More information on retired breeder specifications is available here.
