Figure 2. Quantification of AuNP bound to LNCaP and PC3 cells in vitro.

Figure 2

Cells were incubated at 37 °C for 1 h with 4.0 nM targeted AuNP-streptavidin: biotin-PEG12-CTT54, 6.6 nM non-targeted AuNP-streptavidin, or 4.0 nM AuNP-streptavidin:biotin-PEG12-CTT54 blocked with CTT54. The total amount of AuNP bound to the cells was quantified by ICP-OES and expressed as the percentage of the injected dose (% ID). Values are the averages of one to two individual experiments (two to three replicate samples per experiment) with the standard deviations represented by error bars. *Indicates a significant difference (P < 0.05) compared to AuNP-streptavidin:biotin-PEG12-CTT54 in LNCaP cells.
