We strive to have animals available out to at least the 50% survival age, but availability fluctuates due to changes in demand. An idea of the oldest available for each strain is available at http://www.nia.nih.gov/ResearchInformation/ScientificResources/OldestRodentColonies.htm, but the ages listed on this website are up-dated monthly and are intended only as an approximation. Contact the order desk (rodents@nia.nih.gov) for availability of specific strain/gender/ages.
