- Reported to have a higher resistance to respiratory problems than some albino outbred rats.
- Uses include behaviour studies, diet induced obesity, neurology, toxicology and ophthalmology.
- The Long Evans outbred model was developed by Dr. Long and Dr. Evans in 1915 by intercrossing Wistar Institute white female rats to wild grey male rats. Simonsen Laboratories received stock from the University of California Berkeley in 1949. The rats were derived by embryo transfer in 1975.
