Order

Availabilities

Requesting frozen sperm or embryos is generally advisable wherever possible, in order to minimise the shipment of live mice.

Due to the dynamic nature of our processes strain availability may change at short notice. The local repository manager will advise you in these circumstances.

* In addition users have to cover all the shipping costs (including the cost for returning dry-shippers, where applicable).
