Benefits of Cryopreservation

  • Save money on animal vivarium costs
  • Free up valuable animal space for current research projects
  • Protect against genetic drift
  • Ensure the safety and survival of your line
  • Guard against spontaneous loss of a phenotype
  • Protect against diseases and breeding cessation

Sperm Cryopreservation

MMRRC at UNC offers sperm cryopreservation as an easy and cost-effective option to preserve your strain using the new Jackson Labs protocol. Sperm cryopreservation works best with single gene mutations and common genetic backgrounds, but is available to all mouse lines.

Sperm cryopreservation starts at $525. Click here for more information.

Embryo Cryopreservation

MMRRC at UNC offers embryo cryopreservation as a highly effective way to preserve your line. Embryo cryopreservation is recommended for lines with multiple genetic mutations or uncommon/mixed backgrounds.

Embryo cryopreservation starts at $1260. Click here for more information.

If you have a mouse line that is published, please visit to apply for strain submission to our public repository. If accepted, there will be no fee for services. However, we will publish the strain as being available to the research community and we will take responsibility for distributing the strain to those requesting it.

It is our policy, as well as NIH’s, that all published strains should be deposited in the public repository for research community use. For strains made by investigators from other institutions but imported into UNC, we suggest that you to contact the originating investigator to encourage them to submit the strain to the public archive. If for any reason this is not possible, we will consider archiving the strain for you in the UNC private archive.
