From: Grafting of short elastin-like peptides using an electric field

DF plots reveal that peptide charge, salt and AEF influence grafting mechanism. Data are shown from the grafting of (a) uncharged ELP (light color) and (b) (−)charged ELP (bold color) at different grafting conditions: − 0.3 V AEF in DI water (light blue and blue, respectively), + 0.3 V AEF in DI water (pink and red, respectively), no AEF in DI water (gray and black respectively), and no AEF in 0.5 M NaCl (light orange and orange respectively). All voltages are vs. a Ag/AgCl reference.
