IGF::OT::IGF Development and Maintenance of a Multigenotypic Aging Rat Colonies

拟议合同的目的是开发、维护和分发来自不同基因型的老年大鼠常住群体的动物，供研究人员用于衰老研究。在NIA、其他研究所和退伍军人管理局的支持下，许多研究者在他们的研究中使用NIA的大鼠，并依赖于NIA为他们的研究提供老年大鼠。提供老年大鼠的供应对于NIA受助人实现NIA研究目标至关重要。

The purpose of the proposed contract is to develop, maintain and distribute animals from a standing colony of aged rats of various genotypes for use by investigators in studies of aging. Numerous investigators, supported by the NIA, other institutes, and the Veteran's Administration, use NIA rats in their research and are dependent upon NIA for access to a supply of aged rats for their research. Provision for a supply of aged rats is essential to the achievement of NIA research objectives by NIA grantees.
