TCDM provides possibility to ship mouse embryos and sperm.Freshly collected preimplantation mouse embryos from 1.5 to 3.5 dpc can be shipped at ambient temperatures within 48 hours.

  • Cryopreserved embryos and sperm may not be warmed above -140°C at any time and can be shipped in a dry liquid nitrogen shipper available at the TCDM. It is essential to attach the original cryopreservation and thawing protocol.

The advantages of shipping embryos include cost of shipment as well as simplified and relatively rapid rederivation of imported strains into SPF colonies. Most pathogens are unable to penetrate an intact zona pellucida and infect preimplantation-stage embryos, thus by shipping embryos, quarantine at the receiving animal facility can be avoided. Therefore it appears to be a fast, cheap and effective way to ship mice and clean them up.
