Depositors can provide EMMA with a material transfer agreement (MTA). EMMA will not ship the strain until the recipient has signed this MTA. The MTA applies in relation between provider (depositor) and recipient. EMMA only acts as distributor.

Anybody who wants their mutant mouse strains cryopreserved may deposit strains with EMMA. However depositors must be aware that these strains become freely available to other researchers after being deposited.

Several factors such as the mode of cryopreservation (sperm or embryo freezing), the genetic background and the health status of the mutant strain imported to EMMA influence the time required before a strain becomes available for distribution. Usu...

On the INFRAFRONTIER home page you can find a submission form, which you should complete and send to EMMA via the website. On the submission form you will be asked to give contact information, the type and description of your mutation, the phenoty...

EMMA freezes at least 500 embryos per strain.

EMMA can grant a ‘grace period’ of up to 2 years. During this ‘grace period’ the mice will be archived by EMMA but will not be published on the EMMA homepage. If you wish to make use of the ‘grace period’, you can either complete the respective fi...

The depositor has to bear the expense of shipping the mice to the EMMA institute responsible for archiving the strain. However, EMMA does not charge the depositor for archiving mouse strains.
