The world’s first life insurance for your valuable mouse strains.
PolyGene freeze internal strains, both, to have safe back-up, and to be able to maintain a minimal size of holding colonies. We found that even for actively managed mouse strains, cryopreservation permits to reduce the size of breeding colonies and saves money, headaches, ethical concerns, and provides security.
We do sperm, because we’re good at revitalizing and don’t require the easier-to-thaw but more expensive freezing of fertilized embryos.
Cryopreservation of mouse sperm
PolyGene offers standard services with extended quality: older males are accepted and test-bred, free additional freezing upon unsatisfactory viability is included, and in vivo fertility validation and quality control is applied by default. The validation services yielding fertilized embryos developing to blastocyst stage make an expensive retransfer quality control step unnecessary.
