The Wistar Hannover GALAS Rat

Summary Description: The Wistar Hannover has proven to be exceptionally well suited for 2 year carcinogenicity studies. It has a relatively low body weight, even when fed ad libitum, and its survival rate on 2 year studies generally exceeds 75% for both males and females. RCC, an internationally recognized contract research organization, compiled control data on Wistar Hannover rats for nearly two decades. Several recent 2-year studies using RCC-originated Wistar Hannovers have confirmed the stability of stock’s characteristics.   

Origin:  In 1989 RCC obtained 156 breeding pairs of Wistar Hannovers from Dr. Willy Heine, Zentralinstitut für Versuchstierzucht (ZfV), Hannover, Germany. The stock was hysterectomy derived at RCC in 1989. Genetic drift in each colony of Wistar Hannovers is minimized through the use of the Poiley rotational breeding system and revitalization of the stock with cryopreserved embryos (most recent revitalization completed in 1998).  Each Member of GALAS obtained in excess of fifty (50)Wistar Hannover breeders from RCC in late 1998.

Features:  The Wistar Hannover GALAS rat is used as both a toxicology model and a general, all purpose outbred model for use in biomedical research.   Its body weight averages less than Sprague Dawley rats yet it exhibits comparable reproductive performance. Coat Color:  Albino
