Type: Gene
Species: Mus musculus (mouse)

Genetic Alterations
Single-base substitution generating a premature stop codon in exon 23 of the Dmd gene.
Genotype Determination

Homozygous: At young adult age, the CJ.B10ScSn-Dmdmdx mice show classic dystrophic pathology and muscle force reduction as the original mdx mice. However, future studies are needed to determine whether the lifespan is altered and whether aged CJ.B10ScSn-Dmdmdx mice may show a phenotype different from that of C57BL/10ScSn-Dmdmdx/J.

Hemizygous: Not evaluated

Strain Development

This strain was developed by crossing the C57BL/10ScSn-Dmdmdx/J mouse with the BALB/cJ mouse. At each generation, mice positive for Dmd were crossed again with BALB/cJ for greater than 7 generations.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

3 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
