Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Targeted Mutation Mating System Homozygote x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator Adrian Bird, University of Edinburgh Generation ?+F1 (09-JAN-08) Strain Description
These mice possess two functional loxP sites flanking exons 3-4 of the targeted gene on the X chromosome. Homozygous females and hemizygous males are viable and fertile. Northern blot analysis showed the expected mature transcript from the Mecp2lox locus. Also detected was an unspliced beta-globin transcript that was introduced into the locus as part of the targeting vector. When these mutant mice are bred to mice that express cre recombinase, resulting offspring will have exons 3-4 deleted in the cre-expressing tissue(s). Mice with this X-linked floxed mutation may be useful in neurological and developmental studies of Rett syndrome.For example, when crossed to a strain expressing Cre recombinase in nervous tissue (see Stock No. 003771), this mutant mouse strain develops a neurological phenotype that mimics Rett syndrome.
Strain Development
A targeting vector was designed to insert a loxP site upstream of exon 3, as well as a human beta-globin intron 2 and polyadenylation signal followed by a loxp-flanked TK-neo cassette all downstream of the stop codon in exon 4, of the targeted gene. The donating investigator reports that the "middle" loxP site (just 5' of the TK-neo cassette) is non-functional; thus only the loxP sites upstream of exon 3 and downstream of the TK-neo cassette are functional. The construct was electroporated into 129P2/OlaHsd-derived E14TG2a embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts, and chimeric offspring were bred to C57BL/6 mice. Heterozygous females (with exons 3-4 flanked by functional loxP sites) were mated with wildtype C57BL/6 animals. The resulting hemizygous males were bred with heterozygous females to generate homozygous females. Homozygous females and hemizygous males were bred together for many generations prior to arrival at The Jackson Laboratory.

| Molecular Note | Insertion of a neomycin resistance cassette into the gene introduced loxP sites that flank exons 3 and 4, and added an intron and polyadenylation signal from the human beta globin gene. From the mutated allele, Northern blot analysis detected the wild type mature transcript and also a transcript in which the beta globin intron was unspliced. [MGI Ref ID J:67910] | ||

Estimated Available for Sale Date:
Can not yet predict an estimated Available for Sale date; Colony breeding poorly.
Please note: Estimated available for sale dates are provided to keep customers better informed on strains under development. Please note that our Colony Managers routinely monitor the target date and edit it based on breeding performance and other factors. The length of time it takes to make a new strain available for sale depends on genotype, age, number of animals sent by the Donating Investigator, breeding performance, additional strain development (backcrossing, making homozygous), and anticipated demand for the strain/interest registered.
