From: High-resolution NMR characterization of low abundance oligomers of amyloid-β without purification

Comparison of 1H/15N HSQC spectra of the freshly dissolved (red) and the spin-X-isolated disordered oligomer (blue) of Aβ1-40 (after 4 days) recorded from a 900 MHz spectrometer.
Both experiments were performed in 10 mM phosphate buffer, pH 7.4 and 10% D2O at 25 °C.
