Sperm and Embryo Reconstitution

While cryopreserving your valuable genetically engineered animals is an important part of protecting your research against unforeseen events, having the ability to recover live animals from frozen stock quickly and efficiently is equally critical to safeguarding your lines. After you've preserved your line, we can help you recover it. You can use our cryorecovery services for stock preserved by Charles River or an outside source.
