Aged Rodent Colonies Handbook

Oldest Ages Available in NIA Aged Rodent Colonies

This page was last updated on: August 15, 2016.

We are currently entering newly re-derived foundation stock into the barriers housing the mouse colony, barrier F40 first and then R12 after the quarantine on F40 is lifted. Post-transfer health monitoring will take approximately 6 weeks for each barrier, during which time no shipments will be made from that barrier. This process might impact the oldest available mice during this time, since all shipments must be made from just one barrier

Notice: The NIA has long provided biological resources to the research community to facilitate research on the biology of aging. As of January 1, 2014, the NIA will no longer charge users for the biological resources, nor any related shipping fees due to a new interpretation of the regulations that govern contracting. Notice Regarding Pricing.

The information below is updated monthly, but NIA does not guarantee the information is accurate at all times. The oldest age available is dependent on demand from the research community, which is subject to change. Contact the order desk (rodents@nia.nih.gov) for more specific information on availability of specific strain/gender/ages. Special instructions such as "No Tumors" or "No Cataracts" may lower the age of the oldest available.

Note: Due to limited availability, we cannot age animals out past the available ages for individual requests.
