Figure 4From: Anti-HER-2 engineering antibody ChA21 inhibits growth and induces apoptosis of SK-OV-3 cellsChA21 induces death of SK-OV-3 cells in vitro with PI staining. SK-OV-3 cells were incubated with ChA21 (0.2 or 5.4 μg/ml) for 72 h, and flow cytometric analysis was used to measure the death rate. Significant differences in death rates are represented by asterisk (P < 0.05) and double asterisk (P < 0.01).Back to article page
