Fibril morphology as a function of the net molecular charge. (A) Electron micrographs of negatively stained fibrils (c = 1 mM, t = 1 month) from samples where the net charge on the molecule is +1. (B) Electron micrographs of negatively stained fibrils (c = 1 mM, t = 1 month) from samples where the net charge on the molecule is −1.
