Size Matters: New Tailing Policy

The IACUC approved a new rodent genotyping policy at the July 2013 meeting. In short, the new tailing guideline allows up to 3 mm of tissue to be removed in mice ≤ 28 days of age without anesthesia or analgesia. Any deviations require strong scientific justification and a separate approval from the IACUC. Check out the full policy here.
