Figure 4. ND-Trx3 and fluorescently labeled thioredoxin bioconjugate binding to cell lines.

Figure 4

DU-145 cells were incubated for 1 min in growth medium containing PBS with ND-Trx3 or Trx-F over the indicated concentration ranges. Increasing the concentration of Trx-F to 8 μM did not enhance fluorescence beyond that observed with 4 μM.

ND-Trx3: Nanodevice; PBS: Phosphate-buffered saline; Trx-F: Fluorescently labeled thioredoxin bioconjugate.
