Surfactant properties of amyloid polypeptides. Panel a: Effect of the peptide AChE586–599 at pH 3.0 and pH 7.0 upon surface tension, measured using the optical method and expressed in absorbance units. The surface tension as measured by drop shape analysis is shown for the highest concentration at each pH. Panel b: Effect of peptides Aβ1–16 and Aβ1–40 upon surface tension at pH 7.0, also expressed in absorbance units.
