Figure 6From: Novel pH-sensitive nanoformulated docetaxel as a potential therapeutic strategy for the treatment of cholangiocarcinoma Flow cytometer analysis of cell apoptosis using annexinV-FITC and PI staining. The cells were exposed with free DTX and CSH-DTX at a concentration of 100 ng/ml and 1000 ng/ml and incubated for 24 h. **p < 0.01 is the statistical difference CSH-DTX and free DTX.Back to article page
