Figure 7From: Base excision repair of ionizing radiation-induced DNA damage in G1 and G2 cell cycle phasesThe percentage cleavage of oligonucleotide substrate containing furan lesion. The radiolabeled oligonucleotide substrate was incubated with cell extracts prepared from either unirradiated or 3 Gy irradiated cells collected at various time points. The reaction products were separated on polyacrylamide gel and the incised fragments were quantified to calculate the percentage cleavage at the furan site.Back to article page
