Major collections

The European Mutant Mouse Archive (EMMA) comprises over 8000 mutant mouse lines that are cryopreserved as frozen sperm and/or embryos. These mutants carry targeted, transgenic, endonuclease-mediated, induced and other types of mutations. A major part of the repository consists of strains donated to EMMA by individual researchers.

In addition, EMMA has built up major collections from large-scale projects which include:

  • The Wellcome Trust Knockout Mouse Resource with strains generated by Deltagen and Lexicon


Research tool collections include:


Additionally, EMMA has manually curated the nomenclature, description etc. of several archived mouse strains that have been reported to constitute specific disease models. The users can now look for diseases of interest and check if appropriate mouse models, suitable for their research, are available.


All EMMA strains can be searched for and ordered from the list of available EMMA strains.
