|
The Lewis rat is a descendant of the Wistar Commercial Stock of rats. The
Wistar can be traced back to Donaldson who established a colony at the
Wistar Institute. The rat was cesarean derived in 1999 and fostered onto
CVF® rats.
Colony histories contain some possibility of error. This information is being provided to the best of Hilltop's knowledge. |
The coat color of the rat is albino. The rat colony is an inbred colony. Animals are propagated by brother x sister mating. The colony at Hilltop Lab Animals, Inc. is a closed colony and has been so since 1999. Closed colonies do develop qualities causing the rats to be uniquely suited to certain types of research. |
