Cryopreservation of your genetically modified mouse strains will help save housing cost for lines that are not actively used for experiments. More importantly, cryopreservation of precious mouse lines will help prevent genetic drift, minimize the impact of disease outbreak and protect against unanticipated disasters and events that lead to cessation of breeding or sudden loss of the line. While embryo cryopreservation is more costly than sperm cryopreservation, it is a more reliable way to archive mouse lines and much easier and less costly to subsequently revive the mouse line. To recover a line, it is a simple thaw and embryo transfer into a pseudopregnant recipient. Please contact the CMGM for details on the process of superovulation/mating/harvesting of your mouse line.
Please submit a Embryo Cryopreservation Request Form to start the process of freezing a line.
There is an additional yearly storage fee for each cryopreserved line that is stored on-site at the CMGM.
