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 widely known.

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 Mouse Nomenclature Guides.

Column	Description	Example **
Strain/Stock ID	The unique ID used by your site to represent this strain.	4369
Strain/Stock Designation	Full strain name.	C57BL/6J-Rag1<tm1Mom> Ins2<Akita>/J
Strain Type	Type of strain, comma-separated list. See below for the accepted list of strain types.	SEG, MSR
State	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.	LM,EM
URL	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.	https://www.jax.org/strain/000001
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)	MGI:1857241
Allele Symbol	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. (Optional)	Rag1<tm1Mom>
Allele Name	Name of the Allele.(Optional, to aid in curation when symbol does not exist in MGI)	targeted mutation 1, Peter Mombaerts
Mutation Type	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. (Optional)	TM
Chromosome	Chromosome on which the Gene is located. (Optional)	2
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)	MGI:97848
Gene Symbol	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 MGI. (Optional)	Rag1
Gene Name	Name of the Gene.(Optional, to aid in curation when symbol does not exist in MGI)	recombination activating gene 1
Order URL	The full Order URL, or strain id to insert into an Order URL template that is to be used to link the strain record displayed in the IMSR to the providers strain order page. (Optional)	https://www.jax.org/orderform?stocknumber=000001
