The e-mouse.org is an online resource that aims to bring together and provide users with all information related to the laboratory mouse and its use as a model organism. Users can find direct links to MRB, a resource management project that provides a dynamic and interactive view of most world wide available mouse resources, as well as the CreZOO, MMdb and Fleming Databases, three more specialised mouse repositories, all developed and hosted at the B.S.R.C. Alexander Fleming Institute. Additionally e-mouse.org provides links to major European and international mouse resources like the Mouse Genome Informatics (MGI), European Mouse Mutant Archive (EMMA), International Mouse Strain Resource (IMSR) and Ensembl. Users interested in retrieving information regarding the use of mouse models are encouraged to visit MRB which provides an index of publicly available mouse resources intended for both bench scientists and bioinformaticians.
