SAXS/WAXS Investigation of Amyloid-ß(16-22) Peptide Nanotubes.

ABSTRACT

This brief report presents an X-ray scattering investigation of self-assembled nanotubes formed by a short peptide. X-ray scattering methods enable multiscale structural elucidation of these nanotubes in solution under the same conditions involved in the self-assembly process. In particular, the dimensions of nanotubes and the crystalline organization within their walls can be determined quantitatively. This is illustrated in the case of amyloid-ß(16-22) peptide nanotubes.
