ThT and TEM analysis of fibril formation of Aβ1–40. a 20 μM monomeric peptide solution of Aβ1–40 was incubated in the presence of 40 μM of the amyloid reporting probe ThT. A steady state of the plateau indicates that monomeric fraction has been consumed and converted to the fibrillar form. b Negative uranyl acetate staining of the Aβ1–40 fibrils analyzed by TEM. Scale bar is 100 nm
