Handling
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Functional Studies - 10-Hydroxycamptothecin, DNA topoisomerase I inhibitor (ab141071)ab2893 staining γH2A.X in HeLa cells treated with 10-Hydroxycamptothecin (ab141071), by ICC/IF. Increase of γH2A.X nuclear expression correlates with increased concentration of 10-Hydroxycamptothecin, as described in literature.
The cells were incubated at 37°C for 6 hours in media containing different concentrations of ab141071 (10-Hydroxycamptothecin) 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 ab2893 (5 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.
