Description
The steel mutations cause deficiencies in pigment cells, germ cells, and blood cells paralleling those caused by the Kit locus mutations. Most steel homozygous mice are severely anemic in utero and die usually at 15 to 16 days of gestation. However, compounds of two Mgf^Sl mutants (e.g. Mgf^Sl/Mgf^Sl-d) are viable, black-eyed white, are usually sterile in one or both sexes, and have severe macrocytic anemia. Heterozygous 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 Mgf^Sl/ Mgf^Sl homozygotes and deficient in the Mgf^Sl/+ 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.

Supply Details

Standard Supply

Cryopreserved. Ready for recovery. Please refer to pricing and supply notes for further information.

Supply Notes

Cryorecovery - Standard. We will fulfill your order by providing at least two pair of mice, at least one animal of each pair carrying the mutation of interest. The total number of animals provided, their gender and genotype will vary. Please inquire if larger numbers of animals with specific genotype and genders are needed. Animals typically ship between 13 and 16 weeks from the date of your order. If a second cryorecovery is needed in order to provide the minimum number of animals, animals will ship within 25 weeks. IMPORTANT NOTE: The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 (from U.S.A., Canada or Puerto Rico only) or 1-207-288-5845 (from any location).

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.
