Colony History: Long Evans - Hla®(LE)CVF®
Complete viral antibody profiles, gross pathology profiles, bacteriology profiles, growth charts, and blood chemistries are available.
|
The Long Evans rat is a descendant of Wistar female rats crossed with a
gray male rat of unknown origins (believed to be wild) by Dr. Long and
Dr. Evans in 1915. The Wistar can be traced back to Dr. Donaldson who
established a colony at the Wistar Institute. Hilltop rederived the
line by cesarean section. |
The coat color of the rat is white with a black/brown hood. The eyes are pigmented. The rat colony is maintained as an outbred colony. The colony at Hilltop Lab Animals, Inc. is a closed colony. Closed colonies do develop qualities causing the rats to be uniquely suited to certain types of research. |
Colony histories contain some possibility of error. This information is
