text: By contrast, two systems (i.e., the structures formed by α-lactalbumin and αB-crystallin) appear from AFM images to (i) have an irregular morphology typical of the species, often described as protofibrils, observed before the assembly of mature amyloid fibrils (15), and (ii) indeed have substantially lower elastic moduli of 0.14 and 0.4 GPa, respectively (green squares, Fig. 2).
