Figure 1.

AFM images of oligomeric and fibrillated Aβ(1–42) preparations from California Peptide and American Peptide Company. Scale bar for the fibrillated species of CA peptide and APC are 750 and 200 nm, respectively. The scale bar for the oligomeric species is 1 μm for both samples. Height data indicate the fibrillated species of each are 2.8 nm (CA) and 4.7 nm (APC), and the height of the oligomeric species is approximately 12.6 nm.
