Welcome to the International Mouse Strain Resource (IMSR)

The IMSR is a searchable online database of mouse strains and stocks available worldwide, including inbred, mutant, and genetically engineered mice. The goal of the IMSR is to assist the international scientific community in locating and obtaining mouse resources for research. Note that the data content found in the IMSR is as it was supplied by data provider sites.

New The Search box has been improved so it automatically returns strains that contain your query in: Strain designation, Gene Symbol/Name, or Allele Symbol/Name. The Summary Results also have been reorganized to make it easier to contact the holding Site for your strain of interest.

Search IMSR for strains or mutants
For each strain listed in the IMSR, users can obtain information about:
  • Where a strain is available (Holder Site)
  • In what state(s) a strain is available (e.g. live, frozen, germplasm, ES cells)
  • Links to further information about a strain
  • Links for contacting the holder to order a strain or send a query
Example Search Result:

Results of an IMSR search on strain, gene or mutant symbols/names returns a table of matching results, providing links to strain data at the holder's Web site, an email form for specific inquiries, and links to information about mutant alleles at the Mouse Genome Informatics (MGI) website.
