SSB-Seq

Map DNA Single-Strand Breaks

SSB-Seq maps in vivo DNA single-strand breaks (SSBs) on a genome-wide scale (Baranello et al., 2014).In this method, gDNA is isolated and subjected to nick-translation by DNA polymerase I in the presence of deoxynucleotide triphosphates (dNTPs), including digoxigenin-labeled dUTP, and a small amount of dideoxynucleotides. The DNA is sheared, and the labeled fragments are immunoprecipitated with antidigoxigenin antibodies and purified to prepare a sequencing library.

Advantages:

  • Simple protocol

Disadvantages:

  • Locations of breaks cannot be determined accurately
  • Not yet adopted widely by the scientific community


Reagents:

Illumina Library prep and Array Kit Selector
