(a) XANES spectra of Aβ4–16x (x = 1, 2, 3), Aβ4–12x (x = 1, 2) and Aβ4–8x (x = 1, 2) peptides at low temperature. (b) XANES spectra of Aβ4–8/12/16 peptides at room temperature. All peptides are consistent with each other at low and room temperature. This result indicates negligible damage to the sample from radiation during the collection of measurements. |
