Figure 4From: A modified and automated version of the 'Fluorimetric Detection of Alkaline DNA Unwinding' method to quantify formation and repair of DNA strand breaksDNA damage and repair in several different cell systems. HeLa S3 cells (A), Jurkat cells (B) and human PBMC (C) were damaged with 2.3 Gy of X-irradiation (P1). To allow repair, cells were incubated at 37°C for 40 min (R). T and P0 samples were controls. In all cases the fluorescence signal of the P1 samples was lower that the control value P0, and those of the R values higher than the damaged samples P1. Error bars represent SDs from 8 replicates.Back to article page
