Fig. 6

Confocal fluorescence microscopy experiments showing binding of sulfo-Cy5 labeled FUD and 20 kDa PEG-FUD, and lack thereof for mFUD-Cy5, to Alexa Fluor 488 labeled human plasma fibronectin (A488-FN) surfaces assembled by AH1F human foreskin fibroblasts in a glass bottom dish. Each column indicates overlay of listed signal. Overlay of the A488-FN and the peptide-Cy5 signal (last column) reveals colocalization of fibronectin and bound drug. Scale bars = 50 μm
