Figure 5.
Confocal fluorescence representative images of (a) MCF-7 and (b) MDA-MB-231 cells incubated for 4 hr with either F4 or F8 labeled with FITC. For quantification, flow cytometry overlay histotograms of the (c) MCF-7 and (e) MDA-MB-231 cells incubated with either of the forms are depicted for 30,000 cell/sample. The measured relative fluorescence unit for (d) MCF-7 and (f) MDA-MB-231 cells are presented as bar charts (Mean ± standard error, n = 3).
