Figure 3.

The frequency distributions of fibril lengths after sonication for 20 and 40 h are shown for (a) RiAFP, (b) RiAFP in DTT, and (c) SBAFP. In (a) and (b), the bin width is set at 50 nm. For (a), the average length after 20 (40) h is 186 $\pm$ 87 nm (186 $\pm$ 86 nm). For (b), the average length of RiAFP fibrils after 20 (40) h of sonication is 129 $\pm$ 65 nm (130 $\pm$ 60 nm). For (c), the bin width is set at 20 nm. The average length of SBAFP fibrils after 20 (40) h of sonication is 46 $\pm$ 16 nm (47 $\pm$ 19 nm).
