Strain Information
Type Mutant Stock; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Mating System Homozygote x Homozygote (Female x Male) 05-FEB-09 Species laboratory mouse Generation F?+F1 (02-JAN-09) Donating Investigator Douglas Melton, Harvard University Description
These tet-DTA transgenic mice express diphtheria toxin A (DTA) under the control of a tetracycline operator (tetO; also called tetracycline-responsive element (TRE) or tet-operator) and a cytomegalovirus minimal promoter. When bred with another mouse expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), tissue diphtheria toxin A expression can be regulated with the tetracycline analog doxycycline (dox) in the resulting double mutant offspring. These tet-DTA mice may be useful in generating bi-transgenic mutant mice for the reversible, inducible deletion of specific groups of cells.For example, when bred to a strain expressing tTA in cardiac myocytes (see Stock No. 003170 for example), this mutant mouse strain may be useful in studies of human cardiomyopathies.
Development
The tet-DTA transgene was designed with a diphtheria toxin A (DTA) sequence under the control of heptamerized tetracycline operator (tetO; also called tetracycline-responsive element (TRE) or tet-operator) sequences and a cytomegalovirus minimal promoter. This transgene was injected into fertilized B6CBAF2 mouse eggs. Founder animals were bred to outbred ICR mice and then made homozygous prior to arrival at The Jackson Laboratory.

- atrial fibrillation (MGI Ref ID J:128617)
- following tetracycline withdrawal, atrial fibrillation occurs in some mice

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 and Purchasing Information
