... also exam- ined the formation of aggregates of the mutant pro- teins using thioflavine T (ThT)-binding analysis. The results confirmed the role of the regions in fibril forma- tion of Ab in aqueous ... exchange mapping of Ab using NMR revealed that the middle of Ab is involved in a b structure in the fibrils [30]. In contrast, the C-terminal region, including residues 28–42,...
