Figure 2From: Oxaliplatin long-circulating liposomes improved therapeutic index of colorectal carcinomaApoptosis of SW480 cells. SW480 cells treated with free L-oHP (28 μg/ml) or PEG-Liposomal L-oHP (containing L-oHP 28 μg/ml), PEG-Liposomal L-oHP induced marked apoptosis compared with free L-oHP (P < 0.01). A, flow cytometery; B, DNA fragmentation. M: marker (4000 bp). 1: Control. 2: Free L-oHP. 3: PEG-liposomal L-oHP.Back to article page
