Description

Coat: Albino
- Behavioral Disposition: Docile
- Breeding System: Utilizes a global breeding and monitoring system for consistent research outcomes
- Reproductive Performance: Average litter size of 9.5
- Longevity Benefits: Longer survival leading to reduced costs and improved study outcomes
- Tumor Incidence: Exhibits lower spontaneous tumor incidence, reducing research variables and improving animal welfare
- Size Advantage: Smaller body size results in less compound usage and reduced costs
- Lineage and Origin: Derived at Biological Research Laboratories Limited (BRL), formerly RCC, now Harlan Laboratories Ltd., Füllinsdorf, Switzerland, from the original colony at Zentralinstitute für Versuchstierzucht, Hannover, in 1989. Transferred to Harlan Sprague-Dawley, Inc. in 1993 (nomenclature HsdHan®:WIST). Harlan became Envigo in 2015. In 2004, Envigo, now Inotiv, acquired RCC Ltd., and new breeding stock was transferred in 2008 (nomenclature RccHan®:WIST). Unlike competitive models, the RccHan®:WIST rat has been maintained from the original nucleus of 156 breeding pairs in Hannover, Germany. Han® is a registered trademark of Envigo. Harlan Laboratories became an independent entity in 2023.
