As the primary animal model for studying human diseases, maintaining the genetic integrity of thousands of unique transgenic mouse strains and knockout mouse models is both a logistical and financial challenge for research institutions worldwide. Cryopreservation services offer a reliable, space-efficient, and cost-effective solution. The Core Process The core process involves carefully freezing mouse embryos or mouse sperm in liquid nitrogen at -196°C, a state where all biological activity ceases. For embryos, this typically uses a method called vitrification, a rapid freezing technique that prevents damaging ice crystal formation. Thawed embryos can be implanted into surrogate females to regenerate a live mouse colony. Similarly, frozen mouse sperm can be used with in vitro fertilization (IVF) to revive a strain. Importance and Applications This method is crucial for genome research projects like the International Mouse Phenotyping Consortium (IMPC), which aims to characterize the function of every mouse gene. Cryopreserved mouse strains act as a genetic backup, safeguarding decades of research against loss from disease, breeding failures, or natural disasters. Furthermore, it facilitates the shipping of mouse strains globally as frozen samples instead of live animals, reducing stress, cost, and biosecurity risks. Genetic Resource Management For biobanks and research facilities, implementing a robust cryopreservation strategy is essential for reproductive biotechnology and genetic resource management.

Thawing Mice and Rats in a Refrigerator The USDA uses 8-10 hours per 1 pound of meat as a general guideline; a mouse can be expected to thaw in 2 hours, a rat in 4-5 hours. Fail safe rule: place frozen rodents in a refrigerator for overnight thawing and use them the following day.

Make sure your snake is adequately hydrated. Snakes that are dehydrated may be less likely to accept frozen food. Always provide a clean water dish and ensure the humidity levels in the enclosure are appropriate for your snake's species.
