| These mice possess loxP sites on either side of exon 5 in the targeted gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific expression of the gene.
When bred to CD4-cre mice, homozyogous animals have reduced peripheral T cell numbers, abnormal CD4/CD8 expression, and altered response to antigen receptor stimulation. In addition, these mice show autoimmune colitis and asthma-like syndrome. | |||||||||||||||

Generation DefinitionsDonating Investigator Dr. Dan R. Littman, New York University Medical Center Description
These mice possess loxP sites on either side of exon 5 in the targeted gene. Mice that are homozygous for this floxed allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific expression of the gene.When bred to CD4-cre mice, homozyogous animals have reduced peripheral T cell numbers, abnormal CD4/CD8 expression, and altered response to antigen receptor stimulation. In addition, these mice show autoimmune colitis and asthma-like syndrome.
Development
A floxed neomycin resistance cassette was placed in intron 4 and a loxP site was placed in intron 5. The mutation was introduced using 129P2/OlaHsd-derived E14 embryonic stem (ES) cells. Cre expression in the embryonic stem cells excised the floxed neomycin cassette, leaving exon 5 flanked by loxP sites. This line was backcrossed to C57BL/6 for eight generations by the donating laboratory.

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.Ordering Information
