Fig. 2. Localisation of DNR within the different cell lines at various times following treatment. 2×10⁵ cells were treated with 3 μg/ml of DNR, as described earlier. At various times following treatment, a sample of each cell line was analysed by confocal microscopy. The subcellular localisation of DNR within the cells is shown at a magnification of 20×. All the panels are representative of the entire population. The distribution of DNR within HEL-DR cells (not shown) was very similar to that shown for HEL cells. The distribution of DNR within HL-60 and RC2A cells did not alter over the 4 h observation period, and the panels shown were representative of the fluorescence observed after 1 h. (Note: the time course for the analysis of K562 cells was over a period of days).
