Nomenclature: ZDF-Leprfa/Crl

Type: Inbred

Origin: A mutation occurred in a colony of outbred Zucker rats in the laboratory of Dr. Walter Shaw at Eli Lilly Research Laboratories in Indianapolis, IN in 1974–75. Part of this colony containing the mutation was moved to Indiana University Medical School (IUMS), to the laboratory of Dr. Julia Clark in 1977. Several groups of animals with diabetic lineage were identified and rederived in 1981. Inbreeding of selected pairs from this rederivation was done in the laboratory of Dr. Richard Peterson at IUMS. An inbred line of ZDF rat was established in 1985. To Genetic Models, Inc. in 1991. To Charles River in 2001.
