Aged Rodent Colonies Handbook
Oldest Ages Available in NIA Aged Rodent Colonies
This page was last updated on: February 28, 2013.
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.
