We encourage you to participate with the IMSR to
make this database as complete as possible for all worldwide mouse strain
resources. If you or your institution hold mice, cryopreserved gametes or
embryos, or ES cell lines that you distribute to other researchers,
contributing information about them to the IMSR catalog will make them more
Once registered, you will be contacted by the IMSR staff. We
will need to finalize issues such as: your ability to comply with our
recommended submission format; planning the frequency of your submissions;
and other details surrounding the submission process.
The IMSR accepts submissions as files in
tab-delimited text format. Registered providers submit data to an ftp
site where they are picked up and processed by the IMSR. We encourage data
updates at minimum on a 6-month schedule.
- For each Strain ID - Strain Designation - Strain Type - URL combination,
there will be one or more lines in the file.
- If a Strain carries more than one mutation, each Mutation description,
i.e., the set: (Allele ID - Allele Symbol - Allele Name - Mutation Type -
Chromosome - Gene ID - Gene Symbol - Gene Name) will require a separate line.
- Superscripted portions of the name are enclosed in
< >. For more information on nomenclature* of strain names see

||The unique ID used by your site to represent this strain.
||Full strain name.
||Type of strain, comma-separated list. See below for the accepted
list of strain types.
||State in which the strain is held. Like strain type, if a strain is
held in multiple states at a given site, it should be included as a
comma-separated list. See below for strain state abbreviations.
||The full URL, or strain id to insert into a URL template that
is to be used to link the strain record displayed in the IMSR to
the providers strain record.
|MGI Allele Accession ID
||This is the MGI Accession ID for the Allele. Use of this field should make providing allele symbol and name unnecessary. (Optional)
||Allele associated with this gene and strain. If a strain carries
multiple alleles, a separate line is required for each. Please verify
nomenclature* by searching MGI.
||Name of the Allele.(Optional, to aid in curation when symbol does not exist in MGI)
||targeted mutation 1, Peter Mombaerts
||For each mutant allele, specifies the type of mutation that it
represents. Usually there will be only one mutation type per Allele.
Should there be an exception to this rule, these should be submitted as
a comma-separated list. See below for mutation type abbreviations.
||Chromosome on which the Gene is located.
|MGI Gene Accession ID
||This is the MGI Accession ID for the Gene. Use of this field should
make providing gene symbol and name unnecessary. (Optional)
||Gene Symbol for mutation carried in this strain.
If a strain carries multiple gene mutations, a separate line is
required for each.Please verify nomenclature* by searching
||Name of the Gene.(Optional, to aid in curation when symbol does not
exist in MGI)
||recombination activating gene 1

** For this strain example (C57BL/6J-Rag1tm1Mom
Ins2Akita/J), the submission file would include 2 lines. The first
line is represented in the "Example" column above. Two lines (below) are
required because two mutations are carried in this strain; Rag1<tm1Mom>
