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
Lines generated from the International Knockout Mouse Consortium (IKMC) ES cell resources e.g. EUCOMM mice
IKMC strains available from EMMA
Allele conversion guide
Nomenclature for mutant alleles generated in ES cell lines by the IKMC
Research tool collections include
FLP deleter lines
Lines using the TET expression system
All EMMA strains can be searched for and ordered from the list of available EMMA strains.
