Many factors are involved in end joining (EJ) repair of double strand breaks. Here the authors present a method to identify a chromosomal break repair event that requires classical non homologues end joining (C-NHEJ) using Cas9-based end joining tools, and define a role of CNHEJ factor XLF in repair.
