Nona-Arginine Facilitates Delivery of Quantum Dots into Cells via Multiple Pathways
Figure 6
Energy inhibition reduced internalization of QD/SR9 (150 nM; 1 : 20; 1 hour). (a) Control cells. (b) Cells pretreated at C for 30 min then incubated with QD/SR9 for an additional 1 hour. (c) Cells pretreated with a metabolic inhibitor mixture for 1 hour then incubated with QD/SR9 for an additional 1 hour. Images are from a single plane of Z series. (d) Fluorescence intensity. Values are from three independent experiments ( versus control).
