List of models
Type: Outbred rat
Colour and related genotype: black hooded rat - a/a, h/h
Origin: CSAL (Orleans, from Rockland Farm) - 1966
Breeding: Animal with good reproductive performances but not very docile
Fields of research
Behaviour: learning, stress, locomotion, circadian rhythm, aggressiveness
Toxicology: drug addiction, alcohool
Description of our model
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.
Our added value
The « JANVIER LABS Genetic Policy », a specific programme, guarantees less than 1% inbreeding per generation.
Animals with the SPF or SOPF standards.
A gentling policy for docile and easy-to-handle animals.
Optimal stability conditions of our models during shipments, thanks to our dedicated and internal transport service.
A scientific support with a team of Veterinarians and PhD.
