Double-Stranded Break Labeling
Break-seq combines DSB labeling with NGS to map chromosome breaks with improved sensitivity and resolution (Hoffman et al., 2015). DNA trapped in agarose plugs is end-repaired and labeled with biotin. The agarose is then digested by _-agarase, followed by dilution and fragmentation. The fragmented DNA is purified and end-repaired with unmodified dNTPs, followed by A-tailing. The fragments are purified on magnetic beads, PCR-amplified, purified, and used to prepare a sequencing library.
