Evaluation of apoptotic response in HEK cells. (a) Cells were treated with fullerene and its derivatives for 24 hours. Apoptotic cell death was quantified by photometric enzyme-immunoassay. Media and 1  𝜇 M camptothecin (dash line) were used as negative and positive controls, respectively. (b) Cells were pretreated with fullerene and its derivatives for 2 hours, then cotreated with 1  𝜇 M camptothecin for 24 hours. Relative change in apoptosis was compared to untreated cells (Media, dash line), and camptothecin (CAM). Values are presented as means ± SEM of triplicate cultures from two individual samples in each treatment group.
