Sperm cryopreservation

Cryopreservation of strains by sperm, thanks to its simplicity, is now the standard to cryopreserve most mouse strains.
It is recommended if the strain contains only one or two genetic mutations and is on a common genetic background.

Cryopreservation is the ideal solution to protect a valuable strain or to store a strain that is not part of an active study.

With this in mind, The Jackson Laboratory developed a simple, innovative and reliable solution for protecting and storing your strains: the JAX™ Sperm Cryo Kit.

The recovery of frozen sperm via In Vitro fertilisation allows you to greatly increase the number of age and genotype matched mice produced in just a single recovery.

Sperm cryopreservation allows to secure your models:

• Ensuring against production failures
• Ensuring against disastrous events (fire, technical failure …)
• Recommencing microbiota during embryo recoveries

Cryopreservation also enables savings to be made:

• Reducing the number of animal cages in breeding.
• Free up space in your animal facilities: on average 75% of models present in your animal facilities are not in an active study!
• To put in place considered breedings using live animals only during their use
• To facilitate resource sharing.
• Exchanges of straws are easier and more ethical than exchanges of animals.
