Nona-Arginine Facilitates Delivery of Quantum Dots into Cells via Multiple Pathways

Figure 8

Lipid raft/caveolin inhibition decreased QD/SR9 internalization (150 nM; 1 : 20; 1 hour). (a) Control cells. (b) Cells pretreated with nystatin for 30 min then incubated with QD/SR9 for an additional 1 hour. (c) Cells pretreated with filipin for 30 min then incubated with QD/SR9 for an additional 1 hour. Images are from a single plane of Z series. (d) Fluorescence intensity. Values are m e a n ± S D from three independent experiments ( 𝑃 s < . 0 1 versus control).
