- Simple, cost-effective mouse identification using radio frequency identification.
- Open-source, cross platform modular code in Python
- Easily integrated into custom behavioural assessments.
BackgroundAutomation of animal experimentation improves consistency, reduces potential for error while decreasing animal stress and increasing well-being. Radio frequency identification (RFID) tagging can identify individual mice in group housing environments enabling animal-specific tracking of physiological parameters.New methodWe describe a simple protocol to radio frequency identification (RFID) tag and detect mice. RFID tags were injected sub-cutaneously after brief isoflurane anesthesia and do not require surgical steps such as suturing or incisions. We employ glass-encapsulated 125 kHz tags that can be read within 30.2 ± 2.4 mm of the antenna. A raspberry pi single board computer and tag reader enable automated logging and cross platform support is possible through Python.ResultsWe provide sample software written in Python to provide a flexible and cost effective system for logging the weights of multiple mice in relation to pre-defined targets.Comparison with existing methodsThe sample software can serve as the basis of any behavioral or physiological task where users will need to identify and track specific animals. Recently, we have applied this system of tagging to automated mouse brain imaging within home-cages.ConclusionsWe provide a cost effective solution employing open source software to facilitate adoption in applications such as automated imaging or tracking individual animal weights during tasks where food or water restriction is employed as motivation for a specific behavior.
