Figure 2

X-band CW ESR spectrum of sample 1 at different pH (different colors in each panel) and at different incubation times (different panels). (A) Time zero; (B) after 24 h; (C) after 48 h. Black pH = 5; red pH = 6; blue pH = 7; purple the pH of the sample before any pH shift (see Materials and Methods); dark green pH = 8; orange pH = 9; light green pH = 10. Panel A can be compared with Figure 1 in ref (55) for Aβ(1-28) 50 μM. The vertical lines indicate the leftmost parallel band of the two different species (components I and II) identified for Aβ(1-28).
