description <p>Detecting DNA breaks in defined regions of the genome is critical to advancing our understanding of genome stability maintenance. Here, we present exo-FISH, a protocol to label exposed single-stranded DNA in defined repetitive regions of mammalian genomes by combining <i>in vitro</i> restriction enzyme digestion on fixed cells with fluorescence <i>in situ</i> hybridization (FISH). We describe steps for cell harvesting and fixation, slide treatments, and FISH probe hybridization. We then detail procedures for imaging and analysis.</p> <p>For complete details on the use and execution of this protocol, please refer to Saayman et al. (2023).<p>
