Abstract
Translocation sequencing can be used to assess mechanisms of DNA repair and identify genome-wide double-strand breaks (DSBs) accessible to DNA repair machinery. Here, we present a protocol for mapping double-strand DNA break sites across the genome with translocation capture sequencing. Bait DSBs are introduced using a Cas9 nuclease and repaired by the host cell, connecting bait DSBs to other DSBs. Repair sites are detected by isolating bait site DNA, cleaving normal sequence to enrich off-site repair, and next-generation sequencing. For complete details on the use and execution of this protocol, please refer to Switonski et al. (2021).1.
