Internalization of S11e in HT1080 cells. (A) HT1080 cells were incubated with Cy5-labeled S11e at 4 °C or 37 °C, then images were captured by confocal microscopy. (B) After incubating with Cy5-labeled S11e at 37 °C, the two-dimensional (2D) and three-dimensional (3D) images were captured by confocal microscopy. (C) Co-localization of the Cy5-S11e (red) and Mito-tracker (green).
