Sprague Dawley® Outbred Rats
NTac:SD
Order Model #: SD
Color: Albino
Features: The SD rat is a widely accepted, dependable, general purpose research model used in virtually all disciplines of biomedical research including toxicology and pharmacology.
Origin: Taconic SD rats were first obtained in 1970 from the NIH Animal Genetic Resource. The NIH stock originated from Sprague Dawley, Inc. in 1945 and has since been maintained as an outbred closed colony. To maintain genetic continuity with the SDN:SD strain of NIH, Taconic continually receives axenic breeder stock from the NIH Animal Genetic Resource for systematic introduction into Taconic's production colonies.
