Recovery of strain from frozen sperm
You need to recover frozen sperm and you have samples you froze yourself or that you have received from a collaborator. We can help!
Recovery from sperm is used to repopulate animal facilities after transfer, construction, or after a long period of storage when the strain was not part of an active study.
Recovery from frozen sperm provides specific and opportunistic pathogen free (SOPF) animals and this technique is used to limit genetic drift.
Through the use of IVF, the recovery from frozen sperm allows you to obtain a large quantity of age and genotype matched animals quickly.
Allows to breed a model only when it is used
Allows to quickly and efficiently dispose of animals according to the needs
Allows a return to a “T0” on microbiota
Allows to limit genetic drift
Allows to come back to a safe health status of a strain
