Fig. 6.

Individual channel-like structures at high resolution. Two examples are shown for each molecule, in which a central pore can be observed. The number of subunits observed protruding from the surface varies from four to eight subunits. Resolution of AFM images is not enough to resolve individual subunit structures. [Image sizes are 25 nm for Aβ(1–40), 25 nm for α-synuclein, 35 nm for ABri, 20 nm for ADan, 25 nm for amylin, and 20 nm for SAA.]
