The images for Figs 7, 9 and 10 appear incorrectly in the published article. The figure captions are correct. Please see the correct Figs 7, 9 and 10 and their captions here. Seedless Aβ was incubated alone (black) or together with fibrillary Aβ seeds previously incubated with (green) or without (red) a fivefold molar excess of Mosd1. ThT (20 μM) was added to each sample in order to measure fibrillar content. The data were fitted with an asymmetric five parameter fit.
