The European Mouse Mutant Archive – EMMA

With more than 8800 mutant mouse strains and a small but increasing number of rat mutant strains available, EMMA is the primary mouse repository in Europe and the third largest non-profit repository worldwide.

Strain Distribution

Access to over 8800 mouse mutants and a couple of tens of rat mutants.


EMMA archives your mouse and rat mutants free of charge.

Cryopreservation Protocols

Validated protocols and training videos for mouse embryo and spermatozoa freezing techniques, in vitro fertilisation procedures and embryo transfers.

Strain Collections

Strains originated by large-scale projects archived and distributed by EMMA.

The European Mouse Mutant Archive – EMMA

The European Mouse Mutant Archive – EMMA is the INFRAFRONTIER’s non-profit repository for the collection, archiving (via cryopreservation) and distribution of relevant mutant mouse and rat strains essential for basic biomedical research. The laboratory mouse is the most important mammalian model for studying genetic and multi-factorial diseases in human beings. The comprehensive physical and data resources of EMMA support basic biomedical and preclinical research, and the available research tools and mouse/rat models of human disease offer the opportunity to develop a better understanding of molecular disease mechanisms and may provide the foundation for the development of diagnostic, prognostic and therapeutic strategies. EMMA is a founding member of the Federation of International Mouse Resources (FIMRe).

EMMA is supported by the partner institutions, national research programs and by the EC’s Research and Innovation programme Horizon 2020 (H2020-EU. Developing new world class research infrastructures).

EMMA Objectives

EMMA’s primary objective is to establish and manage a unified repository for maintaining medically relevant mouse and rat mutants and making them available to the scientific community. Therefore, EMMA archives mutant strains and distributes them to requesting researchers. EMMA also hosts courses in cryopreservation to promote the use and dissemination of frozen embryos and spermatozoa. Dissemination of knowledge is further fostered by a dedicated resource database.

EMMA – Focused on Reduction and Refinement

The European Mouse Mutant Archive (EMMA) is the primary mouse repository in Europe and the third largest of its kind worldwide. It is INFRAFRONTIER´s most important `product´- a smart, openly accessible platform for archiving and distributing thousands of mouse disease models – currently more than 8800.

EMMA Network

The EMMA network is a partnership of several laboratories and other institutions throughout Europe. The current membership includes:

EMMA is open for the incorporation of new members into the current network and detailed guidelines for this process are established. Please pbagnpg hf if you would like to learn more about how to become a member of the network.

The EMMA network is directed by Professor Martin Hrabé de Angelis who heads the Institute of Experimental Genetics and the German Mouse Clinic (GMC) at the Helmholtz Zentrum München.
