Figure 2From: Base excision repair of ionizing radiation-induced DNA damage in G1 and G2 cell cycle phasesCleavage of oligonucleotide containing DHU lesion. The labeled oligonucleotide was incubated with cell extracts prepared from synchronized G1 or G2 HeLa cells either not irradiated or irradiated with 3 Gy. The cleavage products on the gel were quantified with PhosphorImager.Back to article page
