Spefor has established mature rapid breeding technology and cryopreservation and recovery technology. The preservation of genetic resources adopts sperm cryopreservation and embryo cryopreservation methods. The conservation process generally includes application-customized plan-start experiment-recovery verification-long-term preservation. Can produce 151 animals with unilateral epididymal tail output. After testing, the microbial level meets the SPF level, and no norovirus or helicobacter pylori is detected. It meets and exceeds the national standards and has provided services for dozens of universities, research institutes, hospitals, etc. .

Advantages of cryopreservation

1. Preserve genetic material and establish an experimental animal resource library.

2. Prevent genetic drift during the breeding process of breeding animals.

Model mice without current demand can be conserved to reduce breeding costs and revived when needed.

Compared to live animal transportation, frozen sperm or embryo transportation has better controllable conditions.

Rapid breeding advantage.

Using a small number of animals to quickly obtain an animal population is beneficial for population maintenance and reduces breeding cycles.

Simultaneously obtaining a large number of animals of the same age reduces experimental errors caused by age and makes experimental data more reliable.

3. At the same time, a large number of fertilized eggs can be obtained for research in the field of gene editing.

4. Combined with cryopreservation technology, the cost of breeding is reduced.
