Overview of structural parameters for αS fibrils obtained from atomic force microscopy (AFM) and scanning transmission electron microscopy (STEM)

Fibril heights (nm) and periodicities (nm) were measured from AFM images and mean fibril lengths (μm) from STEM images. Error bars represent standard deviations.

	Fibril height	Fibril periodicity	No. of fibrils (AFM)	Mean fibril length	No. of fibrils (STEM)
	nm	nm	n	μm	N
WT-αS	6.8 ± 1	84 ± 44	83	1.83 ± 0.8	124
NTAc-αS	6.1 ± 1	115 ± 12	108	0.54 ± 0.2	245
Endo-αS	6.7 ± 1	112 ± 19	113	0.70 ± 0.3	194
