Paramagnetic effects on the NMR spectra of isotropic bicelles with headgroup modified chelator lipids and metal ions†
Abstract
We characterized the paramagnetic effects of nine metal ions on NMR signals of isotropic bicelles with headgroup-modified lipids. We found that Mn2+, Gd3+ and Dy3+ show evidence for influencing NMR signals on the surface more than inside and on the disc edge, providing distance information in the bilayers.
