VARI’s Vivarium and Transgenics Core offers cost-effective cryopreservation options for embryos and sperm, which assists investigators in archiving and reconstituting valuable strains. This approach decreases the need to continuously breed valuable mouse models and provides added insurance against genetic drift or loss of the custom mouse lines due to disease outbreak or a catastrophic event. The frozen strains can be reconstituted at any time by implantation into the oviducts of recipient mice. Core personnel adhere to strict quality control protocols to ensure the viability and integrity of mouse lines. For pricing, please contact our team at TransgenicServices@vai.org.
