Description

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.

Detailed description

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).

Development

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.
