Strain Information
Former Names B6.129-Gt(ROSA)26Sortm1(EGFP)Luo/J (Changed: 01-DEC-06 ) Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Additional information on Congenic nomenclature. Species laboratory mouse Generation N5pN1 Donating Investigator IMR Colony, The Jackson Laboratory Description
Homozygous and heterozygous mutant mice are viable and fertile, and manifest no gross behavioral or phenotypic abnormalities. These mutant mice carry an EGFP construct in which the N- and C-terminal coding sequences are interrupted by the beta-actin intron in-frame. Despite the presence of this intron, high EGFP expression in every cell can be visualized in vivo and in fixed tissues.These mutant mice were designed as an EGFP-expressing control strain for use with MADM (mosaic analysis with double markers) mice (See Stock No. 006041 [EGFP/Dsred2] and Stock No. 006067 [Dsred2/EGFP]). Using the MADM system, a researcher can generate genetic mosaics in which an individual organism contains somatic cells of different genotypes. This allows the researcher to ascertain lineal relationships and pleiotropic gene function in multicellular organisms. These mice may also be useful in studies of cell differentiation and mitosis, and as a source for GFP expressing cells.
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.
Development
A targeting vector was designed to contain the N-terminal portion of a mutant enhanced green fluorescent protein (mut4-EGFP; Okada et al, Exp Neurol 1999 156:394-406), beta-globin intronic sequence (itself containing a loxP-flanked neomycin resistance gene), and remaining "in-frame" C-terminal portion of mut4-EGFP. This construct (GG) is preceded by the cytomegalovirus beta-actin enhancer-promoter and followed by the SV40 T antigen poly A signal, allowing for ubiquitous and high-level expression of the reporter genes. This entire construct was inserted into the Gt(ROSA)26Sor locus via electroporation of (129X1/SvJ x 129S1/Sv)F1-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were microinjected in C57BL/6 blastocysts and chimeric progeny were established. Mutant mice were bred to 129S1/SvImJ (Stock No. 002448) for one generation, and then intercrossed to homozygosity before arriving at The Jackson Laboratory (as Stock No. 006053). Upon arrival, mice were backcrossed to C57BL/6J for at least 5 generations to establish this colony.

| 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. In some constructs 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. | |||

| Molecular Note | A construct containing the CMV beta-actin enhancer/promoter, SV40 poly(A) signal, and encoding the N-terminal and C-terminal halves of a mutant enhanced green fluorescent protein (EGFP) separated by a beta-globin intron containing a loxP-flanked neomycinresistance gene, was knocked into ES cells at the ROSA26 locus. The two parts of the coding sequence are separated by the intron but still in the same reading frame. Ubiquitous GFP expression occurs in the absence of cre-mediated recombination.

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
