Figure 4. Internalization of PB10 by K562/D cells (upper panel) and Ramos cells (lower panel).

Figure 4

a) and d) display the fluorescence from the lysosensor, indicating that both kinds of cells can uptake lysosensor. Frames b) and e) capture the red signal of PB10, which can only be observed inside K562/D cells. c) and f) merge the signal of both lysosensor and PB10 to show that only K562/D cells uptake PB10.
