Determining the enhanced selective internalization ability of MFSX (IMAGE)
Caption
a) Cell uptake efficiency of Cy5-XQ-2d, Cy5-S-XQ-2d, Cy5-MFSX, and Cy5-MFC by PL45 cells. b) The ratio of Geometric Mean Fluorescence Intensity to Cy5-MFC for Cy5-XQ-2d, Cy5-S-XQ-2d, or Cy5-MFSX uptake by PL45 cell or MCF-7 cells. c) Endocytosis by PL45 cells characterized by confocal images. The cells were respectively treated with 250 nM of Cy5-XQ-2d, Cy5-S-XQ-2d, Cy5-MFSX, and Cy5-MFC at 37°C for 2 h.
