CAG-EGFP (pEMS1277)

CAG-EGFP Description:

The CAG promoter is generally reported to have a wide expression throughout cell types and development (resources). To act as a positive control and to generate new ubiquitously expressing resources, the Pleiades Promoter Project isolated the CAG promoter from the InvivoGen pDRIVE-CAG vector and introduced it into the multiple cloning site (MCS) of Pleiades expression vector pEMS1307 (EGFP reporter flanked by full frt sites) to make plasmid pEMS1277 with CAG driving EGFP. The CAG-EGFP (pEMS1277) was introduced by homologous recombination as single copy insertion into the Hprt1b-m3 locus in the X Chromosome of mouse embryonic stem cells (ESCs) mEMS1218. The resulting PCR validated four ESC lines were mEMS2077, mEMS2079, mEMS2084, and mEMS2096. Chimeras were generated using mEMS2077 this cell line were used to generate the images showing ubiquitous expression as expected of this positive control.

In a parallel experiment, also to generate a positive control, the CAG promoter was introduced into the MCS of Pleiades expression vector pEMS1157 (EGFP reporter flanked by minimal frt sites) to make plasmid pEMS1157 with CAG driving EGFP.

Note: Promoterless negative controls (pEMS1302, pEMS1306, pEMS1313) have also been generated.
