text: Protofibrils have an average height of 4.0 ± 0.5 nm (Fig. 2B) and show periodicities of 60 ± 10 nm with amplitudes of 0.8 ± 0.4 nm (the average height was determined by averaging the cross-sectional height profiles, i.e., perpendicular to the fibril axis, over a significant length of the fibril).
