B6.Cg-Gt(ROSA)26Sortm1(CAG-rtTA3)Slowe/LdowJ
Cat. No.: CEMM-07250741
Common Name: Rosa26-CAGs-LSL-rtTA3 knock-in
The CAGs-LSL-rtTA3 (or Rosa26-CAGs-LSL-rtTA3) knock-in allele has a CAG promoter and loxP-flanked STOP cassette upstream of the third-generation reverse tetracycline-regulated transactivator gene (rtTA3), all inserted into the Gt(ROSA)26Sor locus. These mice are a Cre recombinase-dependent, Tet-On tool strain - following removal of the floxed-STOP cassette, they allow dox-conditional expression of TRE promoter-driven target genes.

| Site of Expression |
When these mutant mice are bred to mice that express Cre recombinase, the resulting offspring will express rtTA3 in Cre-expressing tissues with subsequent expression of a target gene under control of a tetracycline-responsive promoter element (TRE; or tetO) that can be induced/regulated by tetracycline or its analog doxycycline (dox).

| Breeding Considerations |
Mice heterozygous or homozygous for the Rosa26-CAGs-LSL-rtTA3 knock-in allele are viable and fertile with no reported gross physical or behavioral abnormalities. When maintaining a live colony, heterozygous mice may be bred together, to wildtype mice from the colony or to C57BL/6NJ inbred mice. Alternatively, homozygous mice may be bred together.
