From: In vitro detection of cancer cells using a novel fluorescent choline derivative
Cell viability (%) of the tested cell lines. A) Normal cell lines: HEK-293 and HDF; B) Other types of cancer cell lines: HepG2 and U-87 MG; C) Cancer cell lines of interest: HeLa and MCF-7. Cells were incubated with increasing concentrations (5, 12.5, 25, 50, 100 and 200 µM) of CFA (1) for 72 h. Cell viability was determined using the MTT colourimetric assay. The data are presented as the mean of three independent experiments. The lines shown are error bars
