Strain Details
Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Transgenic Mating System +/+ sibling x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator Corrinne Lobe, Sunnybrook & Women's College HSC Generation ?+N1F12+N1F2 (24-APR-08) Strain Description
These transgenic mice constitutively express lacZ under the control of the CMV enhancer/chicken actin promoter. Expression is widespread with notable exceptions being liver and lung tissue. Expression is observed throughout all embryonic and adult stages. When crossed with a Cre recombinase-expressing strain, lacZ expression is replaced with enhanced GFP expression in tissues expressing cre. This double reporter system makes it possible to distinguish a lack of reporter expression from a lack of Cre recombinase expression while providing a means to assess cre excision activity in live animals and cells. Although homozygotes are viable, attempts to breed homozygous mice proved unsuccessful.Strain Development
A transgenic construct containing the CMV enhancer/chicken beta-actin promoter, a loxP-flanked Bgeo reporter/SV40 polyadenylation signal segment, and an enhanced GFP gene followed by a rabbit beta-globin polyadenylation sequence, was electroporated into 129X1/SvJ x 129S1/Sv-derived R1 embryonic stem (ES) cells. ES cells expressing lacZ were selected and utilized in ES cell/diploid embryo aggregation in conjunction with CD1 outbred embryos resulting in chimeric animals. The strain has been backcrossed once to C57BL/6J.

| Site of Expression | lacZ is widely expressed throughout embryonic and adult tissues with notable exceptions being liver and lung; when crossed with a Cre recombinase-expressing strain, lacZ expression is replaced with Enhanced Green Fluorescent Protein expression | ||
| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||
| Expressed Gene | lacZ, beta-galactosidase, E. coli | ||
| Expressed Gene | Bgeo, fusion of beta-galactosidase and neomycin phosphotransferase genes , E. coli | ||
| Promoter | ACTB, actin, beta, chicken | ||
| General Note | Expression of lacZ is widespread in transgenic mice, with notable exceptions being liver and lung tissue. This expression is observed throughout all embryonic and adult stages. | ||
| Molecular Note | This transgene contains a CMV enhancer/chicken beta actin promoter, a segment consisting of floxed lacZ and neomycin resistance genes/SV40 polyadenylation signal, and an enhanced GFP reporter gene followed by a rabbit beta-globin polyadenylation sequence. Expression of lacZ in transgenic mice is widespread, with notable exceptions being liver and lung tissue. This expression is observed throughout all embryonic and adult stages. [J:83045] | ||

Colony Maintenance
| Breeding & Husbandry | This strain arose on a 129 (R1 ES cell line) background and was maintained by the donating investigator as a hemizygote by crosses to wildtype outbred CD1 mice. Although homozygotes are viable, attempts to breed homozygous mice proved unsuccessful. |

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
