ab28 staining p53 in HeLa cells treated with genipin (ab141049), by ICC/IF. Increase of p53 expression correlates with increased concentration of genipin, as described in literature.The cells were incubated at 37°C for 6h in media containing different concentrations of ab141049 (genipin) 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 ab28 (5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
