NAP internalization by Huh-106 cells. Cells were exposed for 24 h to Cy3-tagged versions of REP 2031, REP 2055, REP 2139, REP 2147, and REP 2172. Internalized NAPs were detected by virtue of their fluorescent tag (red) in cells in which nuclei were labeled by DAPI (blue) by confocal microscopy. Scale bars, 10 μm.
