European Mouse Mutant Archive

Complemented with reproductive techniques (e.g. in vitro fertilisation, embryo transfer), the cryopreservation of germplasm and embryos provides a secure and economical management of storing the enormous numbers of new mouse mutants generated enabling their use for future research. To ensure consistent quality, spermatozoa and embryos are frozen and rederived according to EMMA standard operation protocols (www.infrafrontier.eu/knowledgebase/protocols/cryopreservation-protocols).

EMMA's primary objective is to establish and manage a unified repository for maintaining medically relevant mouse 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 via EMMA is further fostered by a dedicated resource database.
