Strain Information

Former Names Acacttm1F    (Changed: 15-DEC-04 ) Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse Background Strain C57BL/6 Donor Strain 129S4 via RF8 ES cell line Generation N11 (09-NOV-05)   Donating Investigator Bob Farese,   Gladstone Inst of Cardiovascular Disease

Description
Mice homozygous for the Soat1^tm1 targeted mutation display tissue specific decreases in cholesterol esterification. Fibroblasts and adrenal membranes of homozygous mutant mice show diminished cholesterol esterification and markedly reduced cholesterol ester levels in adrenal glands and peritoneal macrophages. However, the livers of SOAT1-deficient mice contained substantial amounts of cholesterol esters and exhibited no reduction in cholesterol esterification activity. These findings support the presence of more than one form of esterification enzyme in mammals. A second sterol O-acyltransferase gene (Soat2), expressed in the liver and intestine, has subsequently been identified in mice and humans.

Supply Notes

Cryopreserved Embryos This strain is also available as cryopreserved embryos from our Repository. Orders for cryopreserved embryos are supplied subject to a signed agreement that must be returned to the Customer Service Department after order placement. Experienced technicians at The Jackson Laboratory have recovered frozen embryos of this strain successfully. We will provide you enough embryos to perform two embryo transfers. The Jackson Laboratory does not guarantee successful recovery at your facility. For complete information on purchasing embryos from our repository, please visit our Cryopreserved Embryos web page. 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. This strain is included in the Induced Mutant Resource Colony collection. 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.
