Uptake of the FITC-labeled peptides by triple negative breast cancer cells MDA-MB-468, MDA-MB-231, and MDA-MB-436. Cells (10⁵ or 10⁶/well) were treated with peptides (1 µM) and incubated for 30 min at 37 °C before analysis by FACS. The experiments were repeated twice and done in duplicates for each sample. Control group was treated with DMSO (5%). The table lists the mean fluorescence intensity (MFI) for the FITC positive cells for three independent experiments ± SD.
