Detection and Quantification of DNA Strand Breaks Using the ROPS (Random Oligonucleotide Primed Synthesis) Assay
DNA double strand breaks (DSBs) arise from spontaneous DNA damage due to metabolic activities or from direct and indirect damaging effects of stress. DSBs are also formed transiently during such processes as replication, transcription, and DNA repair. The level of DSBs positively correlates with the activities of homologous and nonhomologous DNA repair pathways, which in turn inversely correlate with methylation levels and chromatin structure. Thus, measurement of strand breaks can provide an informative picture of genome stability of a given cell. The use of random oligonucleotide-primed synthesis for the analysis of DSB levels is described. Applications of the assay for quantitative detection of 3′OH, 3′P, or DNA strand breaks at a cleavage site of the deoxyribose residue are discussed.
