品系来源：This 近交系 colony from the University of Illinois at Urbana-Champaign was derived from Long Evans 封闭群 rats originally purchased from Blue Spruce Farms, Altamont, NY in the Fall of 1982. In order to reduce individual differences, Principal Investigator, Martha U. Gillette, PhD, initiated inbreeding (consecutive brother-sister matings). In March 1993, the colony reached generation #20, defined by the Institute for Animal Laboratory Research (ILAR) as the point during inbreeding at which the strain can officially be considered 近交系. This 近交系 colony continues to be used by Dr. Gillette and her laboratory at the University of Illinois at Urbana-Champaign to research cell, molecular and integrative mechanisms in the brain's circadian clock.
