GenerationN7F13N1
Generation Definitions

Description
Mice homozygous for the diabetes 3J spontaneous mutation (Leprdb-3J) become identifiably obese around three to four weeks of age. Elevations of plasma insulin begin at 10 to 14 days and of blood sugar at four to eight weeks. Homozygous mutant mice are polyphagic, polydipsic, and polyuric. The course of the disease is markedly influenced by genetic background. Homozygous mutant mice on the 129P3/J background exhibit severe obesity but the diabetes phenotype is much reduced.

Genes & Alleles

Gene & Allele Information provided by MGI

 
Allele Symbol Leprdb-3J
Allele Name diabetes 3 Jackson
Allele Type Spontaneous
Strain of Origin129P3/J
Gene Symbol and Name Lepr, leptin receptor
Chromosome 4
Gene Common Name(s) CD295; LEP-R; LEPRD; LEPROT; Leprb; Modb1; OB-R; OB-RGRP; OBR; db; diabetes; leptin receptor gene-related protein; obese-like; obl;
Molecular Note Sequence analysis of the 3J allele revealed a 17 nucleotide deletion beginning at base 1874. This deletion results in a shift of the reading frame, and a premature termination of the protein at the 11th amino acid after the deletion site. The mutation is predicted to result in a truncated receptor without a transmembrane domain and affects all Lepr splice variants. [MGI Ref ID J:40658]

Cryopreserved Mice - Ready for Recovery

Price (US dollars $)
Cryorecovery* $3000.00
Animals Provided

At least two mice that carry the mutation (if it is a mutant strain) will be provided. Their genotypes may not reflect those discussed in the strain description. Please inquire for possible genotypes and see additional details below.

Standard Supply

Cryopreserved. Ready for recovery. Please refer to pricing and supply notes on the strain data sheet for further information.

Supply Notes

  • Cryorecovery of Strains Needing Progeny Testing.
    At least two untested males and two untested females (two pairs) will be recovered (eight or more mice is typical). The total number of animals provided, their gender and genotype will vary. Untested animals typically are available to ship between 13 and 16 weeks from the date of your order. If the first recovery attempt is unsuccessful, a second recovery will be done, extending the overall recovery time to approximately 25 weeks.

    Progeny testing is required to identify the genotype of mice of this strain, as a genotyping assay is not available. This type of testing involves breeding the recovered animals and assessing the phenotype of the offspring in order to identify animals carrying the mutation of interest. We can perform the progeny testing for you as a service or we can ship all recovered animals to you for progeny testing at your facility. If you perform the progeny testing, there is NO guarantee that a carrier will be identified. If we perform progeny testing as a service, additional breeding time will be required. In this case, when a male and female (one pair) are identified that carry the mutation, they and their offspring will be shipped. Delivery time for strains requiring progeny testing often exceeds 25 weeks and may take 12 months or more due to the difficulties in breeding some strains. The progeny testing cost is in addition to the recovery cost and is based on the number of boxes used and the time taken to produce the mice identified as carrying the mutation. Please note that identified pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Please contact Customer Service for more information on the cost of progeny testing for a strain: Tel: 1-800-422-6423 (from U.S.A., Canada and Puerto Rico only) or 1-207-288-5845 (from any location). The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

    Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
    Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 (from U.S.A., Canada or Puerto Rico only) or 1-207-288-5845 (from any location).

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
