ab11169 staining MDC1 in HCT116 cells treated with GANT 61 (ab120904), by ICC/IF. Increase in MDC1 expression correlates with increased concentration of GANT 61, as described in literature.The cells were incubated at 37°C for 4 hours in media containing different concentrations of ab120904 (GANT 61) in DMSO, fixed with 100% methanol for 5 minutes at -20°C 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 ab11169 (1/200 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat 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.
