Strain Registration

Strain: LE/Stm

Symbol: LE/Stm
Strain: LE
Substrain: Stm
RGD ID: 629485
Citation ID: RRID:RGD_629485
Ontology ID: RS:0000431
Previously known as: NBRP Rat No: 0139; MDC-02-14
Type: inbred
Source: National BioResource Project for the Rat in Japan
Origin: The LE/Stm rats were introduced into Saitama Cancer Center Research Institute in 1969 from a closed colony of Long Evans rats maintained in the Ben May Laboratory for Cancer Research, University of Chicago. A mutant with red-eyed dilution was found in 1970 in the Long-Evans colony, and the mutation was fixed by selective mating. Thereafter, they were maintained by sister-brother mating more than F50.
Inbred Generations: F50
Last Known Status: Live Animals; Cryopreserved Sperm
Research Usage Diabetes Obesity; Cancer
