Strain Description
KitlSl-20J is a dominant allele. On the C57BL/6J background heterozyggotes have a light black coat color with lighter tail and feet and a steel colored belly with a belly spot. Heterozygotes of both sexes are viable and fertile. See also Mouse Genome Database entry

General Note

This spontaneous mutation arose in a C57BL/6J breeding colony at The Jackson Laboratory.

Molecular Note Long-range PCR demonstrated that this mutation is an in-frame tandem duplication of exon 3 which also involves duplication of introns 3 and 2. At the junction between intron 3 and intron 2 there is an inverted 141 bp duplication of a sequence found later in intron 2. The duplication of exon 3 results in a loss of function in the expressed protein due either to defective binding to its receptor or failure to activate the receptor once bound. [MGI Ref ID J:86436]

Supply Details

Standard SupplyRepository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.
Supply Notes Cryorecovery - Standard.
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 males and two females (two pairs) will be provided, 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 delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that 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. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery.

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; Email: jaxservices@jax.org.
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.
