Strain Information

Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered Mutant Mice. Mating System Homozygote x Homozygote         (Female x Male) Species laboratory mouse Generation N8+N2F10 (04-DEC-07)   Donating Investigator Ronald Evans,   The Salk Inst for Biological Studies

Description
These mice possess loxP sites on either side of exons 1 and 2 of the targeted gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities.

When bred to a strain expressing Cre recombinase in adipose tissue (see Stock No. 005069 for example), this mutant mouse strain may be useful in studies of insulin resistance.

Supply Details

Standard Supply

Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement.

Supply Notes

Usually shipped between four and eight weeks of age. 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.
