Type JAX® GEMM® Strain - Radiation Induced Mutation
Specieslaboratory mouse
GenerationN10

Strain Development
The steel 18 Harwell mutation, then on a mixed C3H and 101 background, was imported in 1988 from Harwell into NCI, Frederick. There, Peter Donovan maintained it by backrossing to C3H/HeN and C3H/HeJ. In 1993 this mutation was imported from NCI to the laboratory of Eva Eicher at The Jackson Laboratory and the estimated backcross generation at that time was greater than N10. The Eicher laboratory then backcrossed this mutation onto a B6 background using both C57BL/6JEi and C57BL/6J.

Mammalian Phenotype Terms assigned by genotype

The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.

KitlSl-18H/Kitl+

        Background Not Specified
  • lethality-postnatal
  • postnatal lethality (MGI Ref ID J:18280)
    • only 77 mutants of 205 wean age offspring of heterozygote x wildtype matings with normal litter size indicates reduced viability
    • small, pale young tending to die early are occassionally seen at birth
  • pigmentation phenotype
  • belly spot (MGI Ref ID J:18280)
    • occasional belly spot or nose spot
  • diluted coat color (MGI Ref ID J:18280)
    • greyish coat, pale ears, and pale tail
  • head spot (MGI Ref ID J:18280)
  • hypopigmentation (MGI Ref ID J:18280)
  • skin/coat/nails phenotype
  • belly spot (MGI Ref ID J:18280)
    • occasional belly spot or nose spot
  • diluted coat color (MGI Ref ID J:18280)
    • greyish coat, pale ears, and pale tail
  • head spot (MGI Ref ID J:18280)
  • hematopoietic system phenotype
  • anemia (MGI Ref ID J:18280)

KitlSl-18H/KitlSl-18H

        Background Not Specified
  • lethality-prenatal/perinatal
  • prenatal lethality (MGI Ref ID J:18280)
    • intercross of heterozygotes yields only 80 mutant in 147 wean age offspring, fewer than Mendelian prediction, and analysis at embryonic day 17 reveals an excess of moles representing early post-implantation deaths

Standard SupplyRepository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.
Supply Notes 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; 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.
