Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Transgenic Mating System +/+ sibling x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator IMR Colony, The Jackson Laboratory Generation [N?+4]p+N3F15N1F2 (05-DEC-07) Strain Description
The Cre recombinase is under the control of the Mx1 promoter. This promoter is silent in healthy mice, but can be induced to high levels of transcription by administration of interferon alpha, interferon beta, or synthetic double-stranded RNA. When combined with a mutant carrying a gene that has been flanked by loxP recognition sites, the expression of Cre recombinase causes the flanked gene to be removed. This provides researchers with the capability to induce the "knockout" at any time during development. There was ~1% background recombination seen in mice not treated with interferon. The percent deletion of the targeted gene varied depending on tissue type, presumably due to the amount of interferon-responsive cells present or to the availability of interferon in each organ.In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
Strain Development
A transgenic construct containing the mouse Mx1 gene promoter, nuclear localization sequence-modified Cre recombinase and a 2.1 kb fragment from the human growth hormone gene (to provide the splicing and polyadenylation signals) was injected into (C57BL/6J X CBA/J)F2 fertilized eggs. The resulting transgenic mice were crossed to (C57BL/6J x 129Sv)F2 mice for an unknown number of generations. The mice were then backcrossed onto the C57BL/6J background for 7 generations.

| Common Name(s) | Mx-Cre; Mx-Cre 31; Mx1-Cre; Mx1cre; MxCre; | ||
| Mutation Made By | Ralf Kuhn, University of Cologne | ||
| Strain of Origin | (C57BL/6 x CBA)F2 | ||
| Site of Expression | widespread pattern of expression; promoter induced to high levels of transcription by administration of interferon alpha, interferon beta, or synthetic double-stranded RNA; provides capability to induce the "knockout" at any time during development | ||
| Expressed Gene | cre, cre recombinase, bacteriophage P1 | ||
| Cre recombinase is an enzyme derived from the bacteriophage P1 that specifically recognizes loxP sites. Cre has been shown to effectively mediate the excision of DNA located between loxP sites. After the excision event, the DNA ends recombine leaving a single loxP site in place of the intervening sequence. | |||
| Promoter | Mx1, myxovirus (influenza virus) resistance 1, mouse, laboratory | ||
| Molecular Note | This transgene expresses Cre recombinase under the control of an inducible Mx1 promoter, which is silent in healthy mice, and active in the liver and in lymphocytes after induction with IFN or pI-pC. The construct also contains a 2.1 kb fragment from thehuman growth hormone gene. [MGI Ref ID J:105040] [MGI Ref ID J:67927] | ||

Supply Details
| 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. |

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
