Microscopy was carried out on a Tecnai 10 (FEI, Eindhoven, NL) operating at 100 kV with a low electron dose and defocus values of 700–900 nm. For cryo-EM, the fibrils were vitrified on holey carbon support films. Cryo-EM was performed using a Tecnai F20 with a field emission gun operating at 200 kV. Low electron dose images were recorded on Kodak SO163 film at 29,000×, with defocus in the range 1–2.6 μm.","divisions":[{"label":"title","span":{"begin":0,"end":15}}],"tracks":[]}
