Cryopreservation is safely done for an indefinite time so stocks can be preserved from the effects of genetic drift. The cost of cryopreserving a stock is often less than the annual cost of maintaining the stock on the shelf. Features of the Service Cryopreserved stocks are backed up by storage in two locations. Stocks can also be stored at the researchers facility if proper equipment is available. For DNA typing, please inquire.
Researchers can request shipments of the frozen embryos whenever wanted.
The Jackson Laboratory will also reconstitute the embryos and establish a live colony. The cryopreservation service includes importation of the stock to be frozen, hysterectomy derivation and colony expansion of the submitted stock, followed by collection, freezing, and storage of 8-cell embryos.
