(a) Ce6 uptake and (b) fluorescence images of HCT116 cells. For measurement of Ce6 accumulation, cells were exposed to Ce6 or DEX6ss for 2 h and then cells were washed with PBS twice. Then, cells were lysed with lysis buffer for 1 h and then Ce6 concentration in cells was measured fluorometrically. Fluorescence images of cells were observed with CLSM. The presented data was mean ± s.d. from 8 wells of 96-well plates.
