Additional information on Congenic nomenclature. Mating System Homozygote x Homozygote (Female x Male) 12-FEB-08 Species laboratory mouse Generation N11+F5 (08-JAN-09) Donating Investigator Joseph Takahashi, Univ Texas Southwestern Medical Ctr Description
Mice homozygous for this "mPer2Luc" mutation are viable and fertile with no developmental or morphological differences compared to wildtype littermates. Expression of PERIOD2::LUCIFERASE (or mPER2::LUC) fusion protein during peak periods is similar to endogenous pPER2 patterns. Homozygous mice have normal entrainment and circadian behaviors. These mPer2Luc knock-in mice may be useful as a real-time reporter of circadian dynamics in different tissues.Development
A targeting vector was designed to insert the firefly luciferase (luc) gene (followed by a loxP-flanked neomycin resistance gene) in-frame into exon 23 of the wild-type sequence. The construct was electroporated into 129S6/SvEvTac-derived W4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6J blastocysts. Chimeric males were bred to C57BL/6J females. Heterozygotes were backcrossed to C57BL/6J inbred mice for 7-11 generations prior to arrival at The Jackson Laboratory.
