Proven successful recovery using Embryo Cryopreservation

JAX has successfully refined the embryo cryopreservation technique for more than 30 years to recover mice quickly and reliably. In addition to being ideal for strains with multiple mutations, this method also allows you to:

  • Preserve the genetic background of your strain upon recovery
  • Recover the precise genotype of your genetic mutation or transgene, compared to Sperm Cryopreservation
