Description of our service

The proliferation of genetically modified laboratory mice has created unanticipated problems for some researchers and animal facilities. Animal facilities are crowded with strains that are not on active study and valuable strains can be lost to accidents and disasters.

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.

JANVIER LABS is the exclusive commercial provider of this Kit in Europe1. Thanks to this Kit, the cryopreservation of sperm of your strains can be performed by you in your laboratory.
