Same as in Figure 3B, for morphologically homogeneous amylin fibrils with the AMY09, AMY10, and AMY11 labeling patterns (A, B, and C, respectively). Measurements were performed at 150.7 MHz 13C NMR frequency, with a 2.2 ms fpRFDR exchange period and MAS frequencies of 25.00 kHz, 30.00 kHz, and 15.00 kHz (A, B, and C, respectively).
