Related Genotype:Description
This transgenic strain carries the Enhanced Green Fluorescent Protein (Clontech) driven by chicken beta-actin promoter and CMV intermediate early enhancer. The transgene was found to have integrated on the X chromosome. Mice of this strain, and cells derived from them, can be distinguished from wildtype on the basis of fluorescence. Transgene expression is seen as early as ~embryonic day 2.75, as morula stage embryos begin to compact. Expression of EGFP is spatiotemporally widespread, though levels differ between different lineages (e.g., expression is slightly higher in the heart). As the transgene is located on the X chromosome, transgenic males will exclusively transmit the EGFP transgene to their female offspring, providing the basis for a non-invasive sexing assay based on green fluorescence. These mice may be useful for sex discrimination prior to overt sexual dimorphism (embryonic day 12.5), monitoring X-inactivation, and may be a source of fluorescently marked cells/tissues.Development
A transgenic construct containing an Enhanced Green Fluorescent Protein gene (Clontech) under the control of the a chicken beta actin promoter coupled with the cytomegalovirus (CMV) immediate early enhancer, was introduced into (129X1/SvJ x 129S1/Sv)F1-derived R1 embryonic stem (ES) cells. ES cells containing the construct were aggregated with ICR morulae and the resulting chimeric males were bred with ICR females for germline transmission. The transgenic offspring were intercrossed to generate homozygotes. Mice derived from founder line D4/XEGFP were sent to The Jackson Laboratory in 1998 and used to establish the colony on a mixed genetic background. This transgene has been found to have integrated on the X chromosome.

| Site of Expression | Integration is on the X Chromosome. The transgene is expressed in a spatiotemporally ubiquitous manner, with expression being slightly higher in heart than in other tissues. Transgene expression is seen as early as ~E2.75. | ||
| 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. | |||
| Promoter | ACTB, actin, beta, chicken | ||
| General Note |
Transgene expression is seen as fluorescence under exposure to a 488 nm light source. In transgenic mice the reporter may be detected as early as ~E2.75, as morula stage embryos begin to compact. Expression of GFP is spatiotemporally ubiquitous, though levels differ between different lineages (e.g., expression is slightly higher in the heart). No discernible phenotype, other than green fluorescence, has been observed in any mice carrying this transgene. | ||
| Molecular Note | The transgene contains the enhanced Green Fluorescent Protein driven by chicken beta-actin promoter and CMV intermediate early enhancer. Transgenic mice were generated by embryonic stem (ES) cell-mediated transgenesis. The construct was electroporated into R1 ES cells and random integration occurred on the X chromosome just distal of Timp and Syn1. [MGI Ref ID J:69995] | ||
