Strain Description
The multiple steel mutations (KitlSl) behave in a semidominant fashion and cause deficiencies in pigment cells, germ cells, and blood cells paralleling those caused by the Kit locus mutations (dominant spotting alleles). Most of the alleles at steel locus cause severe anemia in utero and death by 15 to 16 days of gestation in homozygous mutant mice. However, compounds of two steel mutants (e.g. KitlSl/KitlSl-d are viable, black-eyed white, are usually sterile in one or both sexes, and have severe macrocytic anemia. Heterozygous steel mice have a diluted coat color with a small amount of white spotting, are viable and fertile, and may have a slight macrocytic anemia. Primordial germ cells are absent in the nonviable steel homozygotes and severely reduced in steel heterozygotes. Mast cells are virtually absent in skin and other tissues of steel mutant mice. Tumors tend to develop in germ-cell-deficient ovaries with advancing age.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. This is the case for the strain above. It should be noted that the phenotype could vary from that originally described.We will modify the strain description if necessary as published results become available.

General Note Numerous experiments have demonstrated that precursors of pigment cells and blood cells of homozygotes behave normally when transplanted to an environment of wild-type cells, and that the locus exerts its effect through action of cells in the microenvironment of the apparently affected cells. This steel allele is semidominant. The original steel mutation arose spontaneously in the C3H inbred strain the Oak Ridge National Laboratory. Primordial germ cells are absent in KitlSl/KitlSl and deficient in KitlSl/+. There is no pigment-forming ability in the skin of KitlSl/KitlSl embryos (J:28098). KitlSl derived-fibroblasts are incapable of binding the KIT receptor, as normal fibroblasts can (J:10749). KitlSl is a deletion of the locus (J:10748)(J:6031).
Molecular Note By Southern blotting, it was concluded that this allele contains a deletion encompassing most, if not all, of the coding region of the gene. A probe corresponding to nucleotides 6 to 685 of the cDNA failed to hybridize to DNA obtained from embryos homozygous for this allele. PCR analysis with primers for sequences at various distances from the Kit gene narrowed the 5' and 3' deletion endpoints to a 350 and a 380 base-pair region, respectively. Sequencing of the product of PCR using primers designed to span the deletion revealed that it extends through 973,366 base pairs on Chromosome 10 between nucleotide positions 99,177,807 and 100,151,173 (NCBI Map Viewer, Build 36.1), with a 4-base pair insertion joining the deletion endpoints, and contains 6 predicted and 3 known genes.

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.

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.
