Strain Details
Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Transgenic Species laboratory mouse Donating Investigator Klaus Rajewsky, Harvard Medical School Generation B6N1pN1 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.
Gene & Allele Details

|---|---|---|---|
| Allele Name | transgene insertion 1, University of Cologne | ||
| 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 Notes |
Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. |

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
