Cytotoxicity of DDS to MCF7 cells by XTT Assay.
The assay was performed using selected concentration (given along with the figure) of (a) FA−DDSdox− and (b) FA+DDSdox−. The comparative cytotoxicity effect of with (internalized) and without (not internalized) folic acid on DDS was evaluated by using the concentrations range of 0.038 to 0.28 μM (DDS) with selected time (from 8.0 hour to 72.0 hours). The cell viability was reported taking untreated control cells as 100%. Results were presented as mean ± SD values run in triplicate and repeated.
