Major collections

The Euopean Mutant Mouse Archive (EMMA) comprises over 5500 mutant mouse lines that are cryopreserved as frozen embryos and/or sperm. These mutants carry targeted, transgenic, 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


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