Figure 4: ESI mass spectra showing peptide aggregation stability for peptide 2 and peptide 1 with and without HFIP.

From: Self-Assembly and Anti-Amyloid Cytotoxicity Activity of Amyloid beta Peptide Derivatives

Figure 4

(a) ESI mass spectrum of peptide 1 diluted in H2O to 2.9 × 10−2 wt%. (b) ESI mass spectrum of peptide 2 diluted in H2O to 2.9 × 10−2 wt%. (c) ESI mass spectrum of peptide 1 diluted in 10% HFIP to 2.9 × 10−2 wt%. (d) ESI mass spectrum of peptide 2 diluted in 10% HFIP to 2.9 × 10−2 wt%. The spectrum section shown in black is magnified 550 times.
