Each session ​includes:

  • thawing one aliquot of cryopreserved embryos;
  • washing the embryos in accordance with guidelines promulgated by the International Embryo Technology Society (IETS) to eliminate the pathogens if necessary;
  • preparation of pseudopregnant females; and
  • transfer of all the embryos into pseudopregnant recipients (Up to 2 pseudopregnant females).

Useful information

  • We will thaw cryopreserved embryos and transfer them to a pseudopregnant female.
  • If the cryopreserved embryos were not frozen by us, the sample and information listed below must be submitted and we will evaluate it for feasibility.
    > At least 3 straws/ vials of cryopreserved embryos for reanimation (Aliquots must be shipped directly to LASEC to ensure proper handling of the samples)
    > Genetic background
    > Thawing protocol
    > QC information for that samples
    > Health reports
  • If the procedure is successful, mice will be transferred to your colony in about 9 - 12 weeks after recovery.
  • The successful rate is highly variable between strains, genetic backgrounds, and quality of cryopreserved embryos.
  • Due to the cost of pseudopregnant animals and labor, every cryorecovery attempt is counted as a session.
  • We do not guarantee that the cryopreserved embryos will survive the thaw process and transfer of viable embryos will result in live births.
  • The number of sessions required could be decided by the user.
  • PCR genotyping is available upon request at additional cost.​
  • A valid AEEC number must be provided prior to commencement of service.
  • Completed service request form should be returned to us prior to commencement of service.
