LONG EVANS Rat
CSAL (Orleans, from Rockland Farm) - 1966
Colour and related genotype:
black hooded rat - a/a, h/h
Animal with good reproductive performances but not very docile
Description of our model and application areas
This model was developed by Dr Long and Dr Evans in 1915. The LONG EVANS rat is the result of a cross between a female albino from the WISTAR Institute and a wild male (Rattus norvegicus) captured near Berkeley and offspring selection.
The LONG EVANS rat is small and resistant to oncogenesis. This strain is widely used in behavioral, learning, ageing (visual acuity less affected than that of albino strains), addiction – especially to alcohol – studies.
Main application and research fields
The growth curve represents an average which reflects the weight variation of the strain measured between 21 and 84 days for males and females.
