Description of our model
This strain was selected by DONALDSON in 1906 at the Wistar Institute (USA), from a batch belonging to Chicago University (RUSSEL-LINDSAY, 1979).
It’s an outbred stock, used in all fields of medical and biological research. Its longevity and high rate of spontaneous tumours make it an ideal choice for ageing studies.
JANVIER LABS’s aged WISTAR rats are males selected at weaning and kept solely for ageing. They are kept in their original barrier rooms in a controlled environment and health status.
Important notice: our aged WISTAR rats have never been used as breeders.
