Cryopreservation: Live Sperm

This service is offered as a means for cryopreservation of a particular mouse strain. It is ideal as a safeguard against infection in the breeding colony or as a means of archiving mice strains that will not be used in the foreseeable future. We use the CARD protocol for freezing. The straws are placed in two liquid nitrogen tanks (USZ and Schlieren) for safeguarding against loss through tank failure. For the rederivation of frozen sperm please refer to the service in vitro fertilization (IVF). 

1. A completely filled out request form
2. The GMO datasheet as requested by the veterinary office
3. Four breeding males at breeding age (minimum 10 weeks old) that mated successfully.

The cost of the service is a one-time service fee of 680 CHF for 2 males and 1200 CHF for 4 males. This includes the duplicated storage in two tanks at our USZ and Schlieren location.
