Integrated EPR signal intensity as a function of titrated Cu2+ at pH 7.4 for the octarepeat, PrP(23–28, 73–91), and PrP-(23–28, 57–91). Peptide concentrations are 1000, 500, and 250 µM, respectively, and the copper ion concentration is reported in equivalents per peptide. All spectra collected at 298 K.
