A549 cells were treated with drug for 1 h before 75nM Lysotracker ® Red DND-99 was added to each well. DMSO (drug vehicle) only was diluted at 30mM, 3mM, 0.3mM and 0.03mM. ( A–D). CQ was diluted 30, 10, 3.33 and 1.11µM ( E–H), BafA1 was diluted to 10, 3.33 and 1.11nM ( I–L) and OM and ESOM were diluted to 100, 50 and 25µM ( M–P) and ( Q–T) respectively. The level of fluorescence was imaged by confocal microscopy (x50 magnification).
