Section 1 Overview
This document describes the procedure for using the Labstamp System to create automated tail tattoos for
mouse identification. The Labstamp System is a significant breakthrough for researchers and scientists for
ensuring accuracy of animal research. The Labstamp System features unsurpassed technology that
automatically applies the most consistent, readable and durable ID to research mice. Its advanced design
overcomes issues associated with traditional visual identification methods. By applying automated tattoos to
mice from weanling to adult, the Labstamp System is setting a new standard to protect the integrity of critical
research with many advantages to the facility, operator and the animal.
IMPORTANT
The Labstamp System was designed and validated for mice. The System was neither designed nor validated for
rats. The System was designed to accommodate a specific range of mouse tail diameters (girth) as is generally
found in mice from weanling to adult. Accommodating such a wide range of tail girth is achieved by using a
combination of red (labelled SMALL) or blue (labelled LARGE) Restraint Cartridge, and yellow (shorter) or green
(longer) Needle Cartridge. For each animal, there is only one Restraint Cartridge and Needle Cartridge
combination that will produce an optimal tattoo (i.e. one that is legible and permanent).
The Labstamp Tail
Gauge must be used for guidance in selecting the correct Restraint Cartridge and Needle Cartridge
combination.
Note: Tail size, and not animal age or weight, dictates the correct and singular combination of Restraint
Cartridge and Needle Cartridge that the user must use.
Using the Labstamp System on mice outside of the tail size range will result in light or incomplete tattoos on
undersized animals, and it may cause harm to the animal or damage to the Needle Cartridge on oversized mice.
Anesthesia is not required for using the Labstamp System. However, please defer to your Ethics Committee,
Animal Welfare Officer, attending veterinarian and/or veterinary services for any animal welfare concerns.
