Supplementary Figure 2: 2D 13C-13C correlation spectra of glucagon fibrils.
From: The peptide hormone glucagon forms amyloid fibrils with two coexisting β-strand conformations
a, Sample 1 spectrum. b, Sample 2 spectrum. c, Sample 3 spectrum. d, Sample 4 spectrum. e, Sample 7c spectrum. f, Sample 8c spectrum. g, Sample 9c spectrum. h, Spectrum of mixed samples 11 and 12. The spectra were measured using 50 ms or 30 ms 13C spin diffusion at 293 or 273 K on an 800 MHz spectrometer under 10–14 kHz MAS.
