At Charles River, we know that mouse and rat cryopreservation provides a permanent archive of your valuable genetically engineered strains to ensure that you will be able to recover live animals at any future date. Cryopreservation of embryos and/or sperm provides an effective way to create a low-cost backup to your live animal colony in the event of a colony disaster and/or store lines that are no longer actively being used. With over twenty years of experience and the knowledge gained from cryopreserving over 10,000 unique genetically engineered lines, our expertise helps ensure that your backup will be there when you need it.
