ab10812 staining histone H3 (acetyl K9) in A549 cells treated with scriptaid (ab120883), by ICC/IF. Increase in histone H3 (acetyl K9) expression correlates with increased concentration of scriptaid, as described in literature.The cells were incubated at 37°C for 24 hour in media containing different concentrations of ab120883 (scriptaid) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab10812 (0.1 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
