“…Separations in Ficoll normally result in better preservation of cell function and morphology. We used different concentrations of Ficoll (1-10%) to planktonic cells (Georgalis et al 2012). FCCP, carbonyl cyanide-4-(trifluoromethoxy)-phenylhydrazone is a widely used protonophore responsible for the collapse of the chemiosmotic membrane potential (Armitage 2001;Kelly and Thomas 2001).…”

“…Using Eq. and a reported hydrodynamic radius Rg=4.7 nm, we estimate c for Ficoll to be 270 g L −1 . From that value, we surmise that 300 g L −1 represents a Ficoll concentration that is near the critical overlap concentration true(bold-italicc bold-italicc) and that 400 g L −1 represents a semi‐dilute solution ( bold-italicc >bold-italicctrue).…”

“…This result makes sense because we expect that weaker helices would be more prone to destabilization by Ficoll. At 300 g L 21 , Ficoll destabilized the N-terminal edge of helical region 1 (residues [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Figure 3 shows that peptide 23-32 is the only segment associated with a-1 that was destabilized in the presence of Ficoll.…”
