23Na and 39K nuclear magnetic resonance studies of perfused rat hearts. Discrimination of intra- and extracellular ions using a shift reagent
(Biophysical Society: Biophysical Journal, 1985-07)
High-resolution 23Na and 39K nuclear magnetic resonance (NMR) spectra of perfused, beating rat hearts have been obtained in the absence and presence of the downfield shift reagent Dy(TTHA)3- in the perfusing medium. Evidence ...
Aqueous shift reagents for high-resolution cationic nuclear magnetic resonance. III. Dy(TTHA)3−, Tm(TTHA)3−, and Tm(PPP)27−
(Elsevier: Journal of Magnetic Resonance, 1984-01)
The isotropic hyperfine shifts induced in the 23Na+ resonance by the shift reagents Dy(DPA)33−, Dy(NTA)23−, Dy(PPP)27−, Tm(PPP)27−, Dy(TTHA)3−, and Tm(TTHA)3− are compared under similar conditions. The last three are ...
