Uptake of CLR1501 in cancer cells compared to normal cells. Flow cytometry of the uptake of CLR1501 (a CLR127 fluorescent analog) by normal cells (HUFI, human skin fibroblasts; MCF10A, human mammary gland epithelial cells) and tumor cell lines. Averages ± standard error (SE) from three repeats per cell type. *p ≤ 0.05, ** p ≤ 0.01 tumor cells versus normal cells. RU=relative units.
