This transgenic mouse line, with an "enhanced" GFP (EGFP) cDNA under the control of a chicken beta-actin promoter and cytomegalovirus enhancer, have widespread EGFP fluorescence, with the exception of erythrocytes and hair. Note that the donating investigator reports that mice homozygous for this transgene die within the first two weeks following birth.
Of note, it has been the experience at The Jackson Laboratory that Stock No. 006567 (C57BL/6-Tg(CAG-EGFP)131Osb/LeySopJ) demonstrates the highest proportion of GFP expressing cell populations in bone marrow, thymus, spleen and peripheral blood when compared to Stock No. 003291 (C57BL/6-Tg(CAG-EGFP)1Osb/J) and Stock No. 007075 (CByJ.B6-Tg(CAG-EGFP)1Osb/J).

The EcoRI sites included in the PCR primers were used to introduce the amplified EGFP cDNA into a pCAGGS expression vector containing the chicken beta-actin promoter and cytomegalovirus enhancer, beta-actin intron and bovine globin poly-adenylation signal. The entire insert with the promoter and coding sequence was excised with Bam-HI and SalI and gel-purified. This strain was generated in C57BL/6 mice.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
