Genetic Alterations

This strain was created by combining alleles from C57BL/6J-KitW-41J/J, B6.SJL-Ptprca Pepcb/BoyJ, and B6.CAST-Gpi1a/EiJ.

The strain is uniquely useful as a recipient of hemopoietic stem cell transplants that does not require irradiation or other conditioning for successful engraftment. Both Gpi1 and Ptprc (also known as Ly5) are used as markers in transplant studies.

Phenotype
This strain was created by combining alleles from C57BL/6J-KitW-41J/J, B6.SJL-Ptprca Pepcb/BoyJ, and B6.CAST-Gpi1a/EiJ.

Kit (KIT proto-oncogene receptor tyrosine kinase) encodes a receptor tyrosine kinase that upon activation phosphorylates multiple proteins and is involved in hematopoiesis, stem cell maintenance, gametogenesis, melanogenesis, and in mast cell development. The KitW-41J remutation consists of a G to A point mutation in the kinase domain at nucleotide 2519 that results in a valine to methionine substitution at amino acid 831 (V831M). Mice homozygous for the mutation are viable and fertile, with mild, normochromic macrocytic anemia, a black-flecked white coat. Loss of endogenous Kit function, conferred by the KitW-41J allele, impairs endogenous mouse hematopoietic stem cells, allowing engraftment of human hematopoietic stem cells without irradiation. The Ptrpc (also known as Ly5) and Gpi1 markers allow donor wild-type C57BL/6 cells, including erythrocytes, to be distinguished from cells of recipient origin. Pepc is closely linked to Ptprc on chromosome 1.
Strain Development
This strain was created by combining alleles from C57BL/6J-KitW-41J/J, B6.SJL-Ptprca Pepcb/BoyJ, and B6.CAST-Gpi1a/EiJ. Both Gpi1 and Ptprc (also known as Ly5) are used as markers in transplant studies.

The spontaneous KitW-41J allele arose on the C57BL/6J background and contains a missense point mutation (G to A) at nucleotide 2519, within the kinase domain, that results in a valine to methionine substitution at amino acid 831 (V831M). The Kit ((KIT proto-oncogene receptor tyrosine kinase) locus is on chromosome 5. Upon arrival, sperm was cryopreserved. To establish our live colony, an aliquot of frozen sperm was used to fertilize B6.SJL-Ptprca Pepcb/BoyJ oocytes.

Colony and Husbandry Information

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-reports.

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email csmmrrc@jax.org.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to csmmrrc@jax.org for more information.

A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Laura Farran.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Laura Farran

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
