Fig. 1: AL59 extract comprises additional polymer decorating the amyloid fibrils.

a Cryo-EM micrographs and b Cryo-ET 2D projections reveal undecorated and polymer-decorated AL59 fibrils, highlighted by yellow and red arrows, respectively. The remarkably shaped polymer beads are encircled in yellow and red for the unbound and amyloid-associated forms, respectively. A thin yellow line indicated the estimated crossover-length. The image scale-bar is valid for both panels. See Supplementary Fig. 1.
