Spectroscopic Characterization of Intermolecular Interaction of Amyloid β Promoted on GM1 Micelles

Figure 3

Carbonyl ¹³C spectra of uniformly ¹³C-labelled Aβ(1–40). Spectral data were obtained using 0.2 mM Aβ(1–40) titrated with GM1 micelles at Aβ/GM1 molar ratios of (a) 1 : 0, (b) 1 : 15, and (c) 1 :  30. In (b), the spectra measured in the presence of ThT are displayed at Aβ/ThT molar ratios of 1 : 0 (black), 1 : 1 (red), and 1 : 2 (blue).
