Figure 3.
pH-dependent fibril formation of H65N-βS and acetylated H65N-βS. pH-dependent fibril formation for H65N-βS (A) and a variant in which the free N terminus is acetylated in the H65N variant (B) are shown. ThT fibrillation assays for both variants show pH dependence, indicating that neither site is responsible for the observed pH-dependent switch.
