Figure 6From: Ionic self-complementarity induces amyloid-like fibril formation in an isolated domain of a plant copper metallochaperone proteinEvidence for amyloid-like fibrils formed by peptide-1. (A). Visible spectra of the Congo red dye at two different pH values (circles pH 4.2 and squares pH 7.2) in the absence (empty symbols) and in the presence (filled symbols) of 50 μM of peptide-1. (B). Thioflavin T (10 μM) emission fluorescence spectra in Tris-HCl 20 mM pH 7.2 buffer in the absence (empty squares) and in the presence of peptide-1 at 200 μM (filled squares).Back to article page
