Figure 7: Detection of early and late apoptosis MDA-MB-231 cells after staining woth annexin V-FITC and PI. Cells were incubated with (a) poly(AMPD-BAC)- g-PEG, (b) poly(AMPD-BAC)-g-PEG-lipoyl-PTX-MMP2 and DTT, and (c) poly(AMPD-BAC)-g-PEG-lipoyl-PTX-MMP2, DTT and MMP-2 enzyme. All tests were performed in triplicates.
