Removal of any pre-existing structures in lyophilised stocks of Aβ-peptide is the critical initial step for controlled aggregation studies. HFIP has been shown to break down β-sheet structure, disrupt hydrophobic forces in aggregated amyloid preparations, and promotes α-helical secondary structure. HFIP treatment of lyophilised Aβ-peptide resulted in a dense, homogeneous preparation of unaggregated peptide and samples can be stored as peptide films.
