Fig. 6.

EM data that corroborate the AFM observation in Fig. 5. Aβ oligomer samples were prepared and named as described in Fig. 5. Representative photomicrographs are shown in (A). Magnification, X50,000; scale bar, 50 nm. Panel B demonstrates the average diameter of particles in each sample. The diameters of particles from randomly selected 250 particles distributed in multiple fields were measured and averaged. Data presented are mean ± standard error from two independent experiments. * p < 0.05.
