JAX® Cryopreservation and Recovery Services

Cryopreservation saves the expense and vivarium space associated with maintaining live breeding colonies not under current investigation while providing a 'back-up' against the loss of mouse colonies due to breeding cessation, disease outbreak, genetic contamination, or natural disasters.

Sperm Cryopreservation Service

The new and proven gold standard technique for cost effectively cryopreserving mouse strains. High fertilization and recovery rates mean colonies can be quickly scaled to meet your needs.

On-site Rederivation and Sperm Cryopreservation

If you have 50 or more strains to rederive or cryopreserve, our "Freeze Team" can rapidly perform the work at your site. We can cryopreserve 120 or more strains a week and scale recoveries to meet your needs.

Sperm Cryo Kit

Our new, money saving, 'do-it-yourself' Sperm Cryo Kit includes the unique reagents, equipment, and detailed and illustrated instructions for cryopreserving mouse sperm yourself. You send frozen sperm to us for QC testing and long term cryopreservation.

Embryo Cryopreservation Services

Our JAX Custom Embryo Cryo Service is best suited for strains that are inbred, maintained as homozygotes, or that have multiple genetic mutations. Our JAX Speed Cryo Service cryopreserves heterozygous two-cell embryos on C57BL/6J, FVB/NJ, DBA/2J, BALB/cByJ, or NOD/ShiLtJ backgrounds.

Cryo Storage Services

We provide safe, secure long term liquid nitrogen storage for cryopreserved mouse germplasm for samples frozen through our services.

Sponsored Strain Distribution Service

Have your strain join the gold standard "J" family! Having JAX distribute your strain saves you time and money and fulfills the NIH mandate to share new model organisms.

Cryorecovery Services

Our Sperm Cryorecovery or Embryo Cryorecovery services can quickly and cost-effectively recover specified and opportunistic pathogen free (SOPF) mice in the quantities you need from stocks we cryopreserve for you. We also offer recovery services for strains cryopreserved by others.

Our experience is the difference

We pioneered and continue to advance the science of reliable, cost effective cryopreservation of mouse strains. We maintain the world's largest collection of mouse germplasm and have successfully cryopreserved and recovered more than 14,000 mouse strains.
