How do i accurately bleed rats by vena caudalis, I\m looking for guidance on the procedure?

30 March 2013 1 3K Report

A procedure with diagrams will be the best.

Yon can either make take a blood sample through the caudal vein with a seringue or only collect blood trough a small incision at the end of the tail. A small trick is to warm a little the rats by putting them close to a lamp for few minutes. If rats are cold, they will be vasoconstricted, then it is difficult to see the caudal vein and to collect blood through an incision.
