Immunofluorescence analysis of telomeres in the GRN163L-treated CD18 cells.

<p>CD18 treated with GRN163L (GRN) or with no drug (CTR) were harvested at the end of the growth curve presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0085155#pone-0085155-g003" target="_blank">Figure 3</a>. Cells were fixed and stained with antibodies against TRF2 (green) and γ-H2AX (red) and were counter-stained with DAPI (blue). Images were visualized on a confocal microscope (Zeiss 510 Meta Confocal Laser Scanning Microscope). Three representative images of each sample are shown.
