Figure 3From: Thailandepsins are new small molecule class I HDAC inhibitors with potent cytotoxic activity in ovarian cancer cells: a preclinical study of epigenetic ovarian cancer therapy TDP-B activates cleaved caspase-3 by immunofluorescence. Representative immunofluorescence staining for cleaved caspase 3 (green) in SKOV-3 ovarian cancer cells treated with 10 nM FK228, TDP-A or TDP-B after 24 h of exposure. The nuclei are stained with DAPI (blue)Back to article page
