A23Na multiple-quantum-filtered NMR study of the effect of the cytoskeleton conformation on the anisotropic motion of sodium ions in red blood cells
Recently, it has been shown that23Na double-quantum-filtered NMR spectroscopy can be
used to detect anisotropic motion of bound sodium ions in biological systems. The technique
is based on the formation of the second-rank tensor when the quadrupolar interaction is not
averaged to zero. Using this method, anisotropic motion of bound sodium in human and dog
red blood cells was detected, and the effect was shown to depend on the integrity of the
membrane cytoskeleton. In the present study, multiple-quantum-filtered techniques were …
