Browsing and searching for mouse lines in EMMA. Relevant strains can be identified by either (i) typing case-insensitive, full/partial terms in the top text field which searches against the affected gene symbols and name, approved international designated and common strain names, phenotype description and EMMA ID, or (ii) browsing through a complete list of lines or partial lists categorised by the affected gene(s), mutant type (targeted, gene trap, transgenic, induced, chromosomal anomalies or spontaneous), research tool [Cre recombinase expressing strains, lines for tetracycline (Tet)-regulated gene expression systems], strains provided by the Wellcome Trust Knockout Mouse Resource and finally strains produced out of the EUCOMM programme. Results are presented as a table of the EMMA ID, affected gene, common and approved international strain names alongside links to order or register interest in ordering a line when it becomes available. Clicking on any of the common strain names pops up a description of the strain.
