Grazing-incidence X-ray scattering patterns of DPPC multibilayers inserted with β-amyloid peptide 1–40 on a silicon wafer at about 306 K under different relative humidities: (A) RH = 36%, (B) RH = 85.6%, (C) RH = 93.66% and (D) RH = 95.09%. The weight ratio of β-amyloid peptide to DPPC is 10 to 1. The dashed lines are the cuts for the intensity distribution profiles shown in Fig. 3(b). The length of the scale bar is 2.5 cm. |
