(a) Immunofluorescence detection of pADPr in GBM cells exposed to 20 mM H 2 O 2 with or without 5 μM ABT-888; scale bar at bottom right = 10 μm. (b) Fluorescence intensity quantification of the pADPr signal estimated using ImageJ (v1.44p, National Institutes of Health, Bethesda, US). Error bars indicate the standard error among 100 cell nuclei.
