Laboratory Animal Identification Methods

A major component to all research is data collection. Through the eyes of the researcher, mice are considered a live data storage device that is fundamental to generating the necessary data. Therefore, the ability to properly identify your study animals is critical to determining the accuracy of your research results.

Charles River Pre-ID™ services enable you to receive animal models that have been identified with the codes you provide us. Our skilled technicians perform all procedures in adherence to the highest standards in aseptic technique and animal welfare, and you have the option to select the identification that is most appropriate for you.*
