Characteristic diameter of zinc-induced aggregates for the studied Aβ isoforms. DLS measurements were carried out within 20 min after the addition of zinc to Aβ solutions. Peptide concentration: 25 μM; zinc/peptide molar ratio: 2. Buffer: 10 mM HEPES (pH 7.4), 150 mM NaCl. Mean values and standard deviations for three independent measurements are shown.
