Tg(CAG-Bgeo,-NOTCH1,-EGFP)1Lbe

A transgenic construct was designed with the CMV enhancer/chicken beta-actin promoter, loxP-flanked STOP sequence (beta-geo reporter followed by SV40 polyadenylation signal), Myc-tagged intracellular portion of human NOTCH1 (IC-Notch), internal ribosomal entry site, and an enhanced green fluorescent protein (EGFP) gene. Prior to cre-mediated excision of the "floxed" STOP sequence, high expression of lacZ is observed in cells and tissues. When bred to Cre recombinase expressing mice, the STOP sequence (and beta-geo) is removed in the resulting offspring, allowing transcription/co-expression of both the intracellular human NOTCH1 (IC-Notch) and EGFP to proceed in the Cre recombinase expressing cells and enabling tissue-specific studies of NOTCH expression using appropriate Cre mice.
