Sensitivity is the key: Dynamic nuclear polarization NMR spectroscopy provides structural information on liposomal vaccines targeting Alzheimer’s disease. DMPC/DMPG/Cholesterol mainly stabilizes extended structures of the lipid-anchored peptide, while in DMTAP/Cholesterol liposomes the peptide adopts a multitude of conformations including random-coil and extended structures.
