 Results of an apoptosis assay on the Bcap‐37 cell line with four platinum derivatives

Drugs	Apoptosis (%)	S phase (%)
Control	0.0	43.9
Cisplatin	44.9**	0.0**
Carboplatin	0.6	44.3
Oxaliplatin	10.2**	31.8
γ‐PGA‐CDDP	14.4**	33.6

Human breast tumor Bcap‐37 cells were treated with cisplatin, carboplatin, oxaliplatin and γ‐PGA‐CDDP conjugate at 100 μM/L for 24 h. The cell cycle was analyzed by FCM assay. **P < 0.01 drugs vs control.
