Cryopreservation and Assisted Reproduction Laboratory

Cryopreservation and Assisted Reproduction Laboratory

  • Offers services for banking unique strains of mice by preserving their frozen germplasm in liquid nitrogen (-196° C)
  • Safeguards colonies against loss due to disease outbreak, genetic drift, or mutation
  • A cost-effective alternative to maintaining strains no longer in use by allowing their removal from the shelf
  • Provides scientific support for researchers performing animal-based research
  • The laboratory has a storage capacity of 44,000 vials
  • As a back-up against any imponderable disaster, a number of vials from each strain are kept at the NCI-Frederick Central Repository

Cryobiology Laboratory

  • Utilizes state-of-the-art techniques that make it possible to offer different options for preserving a given mouse strain
  • Techniques include freezing embryos at different developmental stages, freezing ovaries, and freezing sperm
  • With these options we are able to cryopreserve most inbred, spontaneous mutant, or genetically engineered strains, while maintaining the genetic background and genotype
