Cryopreservation Services

Sperm cryopreservation requires submission of 3, preferably breeding, males, 10-24 weeks of age. You will receive frozen sperm aliquots in sterile CBS high-biosecurity straws.

Embryo cryopreservation requires submission of females, 7-12 weeks of age and males, 10-24 weeks of age.  Preferably the males should be proven breeders.  An ideal number is 10 males and 30 females. You will receive all cryopreserved embryos collected from the donor females you provide (~20 embryos per sterile CBS high-biosecurity straws).

Weather and Shipping

The welfare of the animals is of utmost importance and as we head into the summer months, inclement weather and excessive heat will delay/prevent shipments of live animals.  Be aware that hot temperatures between June and mid-September may negatively impact the ability of couriers to safely ship animals so please plan your live animal orders accordingly.

Animal Models and New Approach Methodologies (NAMs)

NAMs are lab (e.g., organoids and iPSCs) or computer-based methods intended to expand our tools for modeling human biology and disease. While this field is rapidly evolving, the need for animal models remains, especially for situations where a complex biological system is necessary. In addition, animal models serve as vital in vivo controls for the validation and verification of emerging NAMs.
