Description

Strain Information
Former Names STOCK Tg(balancer2)3Cgn/J (Changed: 06-MAR-06 ) Type Mutant Stock; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Species laboratory mouse Generation +N2
Generation DefinitionsDonating Investigator Klaus Rajewsky, Max-Delbruck-Ctr. for Molecular Medicine Description
These transgenic mice carry the Cre recombinase gene under the control of the rat nestin promoter. When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in cells expressing cre, generating a proportion of mosaic animals. All adult organs, including germ-line cells, may be affected. The balancer2 line of transgenic mice show greater variability and instability in their generation of mosaics than the balancer1 line (Stock No. 002858). This variability of the balancer2 line can be of particular benefit if the gene of interest is vital and mosaic individuals are used to bypass lethality.Development
The transgene contains the gene for Cre recombinase under the control of the rat nestin promoter and second intron enhancer. The "NesI2Crec-1" construct was used. B6CBAF2 embryos were injected. The strain is currently on a mixed B6,129,CBA background.

Genes & Alleles
Gene & Allele Information provided by MGI
| Allele Symbol | Tg(Nes-cre)2Wme | ||
|---|---|---|---|
| Allele Name | transgene insertion 2, Werner Muller | ||
| Allele Type | Transgenic (Cre/Flp) | ||
| Common Name(s) | NesI2Crec-I; Tg(balancer2)3Cgn; TgN(balancer2)3Cgn; bal2; balancer2; | ||
| Mutation Made By | Ulrich Betz, Business Group Pharma/Research | ||
| Strain of Origin | (C57BL/6 x CBA)F2 | ||
| Site of Expression | induces variable mosaicism/partial deletion of loxP-flanked alleles before embryonic day 10.5 and in all adult organs (including germline), producing mosaic mice consisting of cells that are either wildtype or mutant for the gene of interest, more variable mosaicism than the "balancer 1" line (Stock No. 002858) | ||
| 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 | Nes, nestin, mouse, laboratory | ||
| Gene Symbol and Name | Tg(Nes-cre)2Wme, transgene insertion 2, Werner Muller | ||
| Chromosome | UN | ||
| Gene Common Name(s) | Tg(balancer2)3Cgn; TgN(balancer2)3Cgn; bal2; balancer2; | ||
| Driver Note | Nes | ||
| General Note | Mice carrying this "balancer 2" transgene show greater variability and instability in their generation of mosaics than do transgenic mice carrying the "balancer 1" transgene. | ||
| Molecular Note | The transgenic construct contained a nestin promoter followed by cre recombinase sequence adjoined to a nuclear localization signal. Intron 2 of the nestin gene was included downstream of a polyadenylation signal. While the endogenous nestin promoter is CNS-specific, Southern blot analysis showed the ubiquitous expression of cre in transgenic mice. Variable mosaicism/partial deletion of the loxP-flanked allele occurs, and it may be detected in all adult organs including germ line cells. [MGI Ref ID J:67926] | ||

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 Information
