How to use

In Vitro:

HL-60 cells treated with Clofilium (0-20 μM; 24, 48, and 72 hours) lead to suppression of viability and proliferation in both time and concentration-dependent manners. Cell viability decreases significantly in HL-60 cells treated with 2.5 μM to 10 μM of Clofilium. Clofilium (10 μM, 12 hours) induces the proteolytic cleavage of inactive procaspase-3, p34 into its active form, p17 and subsequent cleavage of its substrate PARP at 2 h after exposure to 10 mM Clofilium. However, there is no significant change in expression of Bcl-2 and Bax proteins.
