Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Targeted Mutation Mating System Homozygote x Homozygote (Female x Male) Species laboratory mouse Donating Investigator Charles Weitz, Harvard Medical School Strain Description
Mice homozygous for this conditional (floxed) allele possess loxP sites flanking exon 8 of the targeted gene and are viable and fertile, with circadian behavioral rhythms indistinguishable from wildtype littermates. When bred to mice that express Cre recombinase, the resulting offspring will have the exon encoding the ARNTL (BMAL1) basic helix-loop-helix (bHLH) domain deleted in the cre-expressing tissue(s). These Bmal1-floxed mutant mice may be useful in generating conditional mutations (whole-mouse or tissue-specific) to study the role of circadian clock/circadian rhythm in physiological and behavioral regulation.For example, when crossed to a strain expressing Cre recombinase in the retina (see Stock No. 005105), this mutant mouse strain may be useful in studies of the circadian clock of the retina.
Strain Development
Using homologous recombination in a bacterial artificial chromosome (BAC, clone RPCI23-331K23), an FRT-flanked neo cassette (followed by a loxP site) was inserted immediately downstream of exon 8 of the targeted gene. An additional loxP site was added upstream of exon 8 when the targeting vector was excised from the BAC. This construct was electroporated into 129S4/SvJae-derived J1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and chimeric mice were bred to Flpe-expressing mice (see Stock No. 003946) to excise the neo cassette. The resulting offspring were next bred to C57BL/6 congenic mutant mice (non-germline cre mice). After this, mice were selectively backcrossed to C57BL/6J inbred mice for at least 6 generations to contain only the conditional mutation (loxP-flanked exon 8 with a single remaining FRT site) prior to arrival at The Jackson Laboratory.

IMPORTANT NOTE: Prices are based on shipping destination. To view prices, select your shipping destination.
| 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. |
