Figure 5.
Cells defective in FANCJ show increased 1H6 fluorescence. (a) TMS induces elevated numbers of 1H6 foci in FANCJ DT40 chicken cells. FANCJ DT40 cells or cells expressing human FANCJ-WT were either exposed to 5 μM TMS for 2 h or left unexposed, fixed and stained with 1H6 (red) and DAPI (blue). (b) Quantification of the change in 1H6 foci with and without TMS treatment. The graph illustrates the mean ± s.e.m of the G4 foci in each cell. More than 100 cells were scored for each sample.
