Origin

Origin

R. W. Dawley at the University of Wisconsin (USA) established a rat strain that served as the basis for the SD strain by breeding large Hooded male rats and cross-bred female albino rats of Wistar origin. The rat strain was named Sprague Dawley after the developer Dawley and his wife's maiden name, Sprague. This strain was introduced from Charles River (USA) to CLEA Japan, Inc., and its supply was started. Since then, the name of the strain has been changed as follows.

  • Around 1925: Dr.R.W. Dawley at the University of Wisconsin crossed a large, non-standard hooded male rat with an albino female rat from the Wistar strain, and through seven generations of mating, created the foundation for the SD rat.
  • 1964: Animals were imported from Charles River (USA), underwent cesarean section cleaning, and were supplied as "SD-JCL".
  • JCL:SD (1972 to 1980); Changed according to an agreement with the Japanese Society for Laboratory Animal Resources
  • Jcl:SD (1981 to date); Changed according to the International Registry

Use

The Jcl:SD rat is a general-purpose model used for studies in a wide range of fields including safety testing, pharmacology, toxicity, biochemistry, and nutrition.
