Functional Studies - TMPyP4 tosylate, Telomerase inhibitor (ab120793)ab2893 staining ?H2A.X in weri cells treated with TMPyP4 tosylate (ab120793), by ICC/IF. Increase of ?H2A.X nuclear expression correlates with increased concentration of TMPyP4 tosylate, as described in literature.
The cells were incubated at 37°C for 24 hours in media containing different concentrations of ab120793 (TMPyP4 tosylate ) 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 ab2893 (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.
