CAG Promoter (pEMS1157)

CAG 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 pEMS1306 (EGFP reporter flanked by minimal frt sites) to make plasmid pEMS1157 with CAG driving EGFP. The CAG-EGFP (pEMS1157) was introduced by homologous recombination as single copy insertion into the Hprt1b-m3 locus in the X Chromosome of mouse embryonic stem cells (ESCs) mEMS1204. The resulting PCR validated four ESC lines were mEMS1561, mEMS1589, mEMS1590, and mEMS1600. Chimeras were generated using mEMS1589, mEMS1590, and mEMS1600 and the former two cell lines were used to generate the images below 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 pEMS1277 (EGFP reporter flanked by full frt sites) to make plasmid pEMS1277 with CAG driving EGFP.

Note: a promoterless negative control (pEMS1306) has also been generated.
