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).

Laboratory Animal Genetic Reporting (LAG-R) Guidelines Published

The LAG-R framework (Laboratory Animal Genetic Reporting) is a set of guidelines to support more complete documentation of the genetic make-up of animals of all species that are used in research, with the aim of bolstering reproducibility, reliability, and overall scientific rigor. See Nature Communications (https://doi.org/10.1038/s41467-024-49439-y).
