Aβ peptides incubate as aggregates with different properties in isolation or in a complex mixture. (A) AFM scans of surfaces used to measure the length (B–D) and volume (E–G) of aggregates derived from 20 µM solutions of the peptides alone, e.g. Aβ(1–38) (solid line) and Aβ(1–42) (dotted line), or a 20:1 mix of Aβ(1–42):Aβ(1–38) (dotdash line) at the zero ‘0′ time-point and at 24 and 48 h of incubation.
