Strain Information

Type Coisogenic; Mutant Strain; Spontaneous Mutation; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse Generation F233+11p

Development
The underwhite like mutation (uwl) arose spontaneously in the C57BL/6J colony at The Jackson Laboratory in 2004, when that strain was at F223, and has been maintained on that background ever since.

Genes & Alleles

Gene & Allele Information

Allele Symbol		uwl
Allele Name		underwhite-like
Allele Type		Spontaneous
Strain of Origin		C57BL/6J
General Note		The underwhite-like (uwl) mutation is thought to be a remutation to Slc45a2, and allelic to the original underwhite mutation (Slc45a2uw). However, a noncomplementation test was not done since the original underwhite mutation is only availableas cryopreserved embryos.

Cryorecovery of Strains Needing Progeny Testing. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two untested males and two untested females (two pairs) will be recovered, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the overall recovery time to approximately 25 weeks. However, all pups recovered will be sent. 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 (at least two untested pairs) 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 or 1-207-288-5845. Cryorecovery to establish a Dedicated Supply for greater quantities of mice One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845. This strain is included in the Mouse Mutant Resource collection. Genomic DNA is available for this strain from the Mouse DNA Resource.

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.
