Transcription factors control gene expression by binding to noncoding regions of DNA known as  cis-regulatory elements (CREs i.e., enhancer/promoters). Traditionally, cis-regulatory analysis has been carried out via mouse transgenesis which is time1-consuming and nonquantitative. Electroporation of DNA reporter constructs into living mouse tissue is a rapid and effective alternative to transgenesis which permits quantitative assessment of cis-regulatory activity. Here, we present a simple technique for quantifying the activity of photoreceptor-specific CREs in living explanted mouse retinas.
