Figure 7From: Requirement of ATM-dependent pathway for the repair of a subset of DNA double strand breaks created by restriction endonucleasesEffect of ATM inhibition on distribution of foci number. Synchronized normal human diploid cells in G1 were electroporated with 100 U of Pvu II with or without 20 μM KU55933. The cells were incubated for the time indicated before fixation.Back to article page
