Physical basis for the resolution of intra- and extracellular cesium-133 NMR re...

For human red blood cells (RBCs) loaded with Cs' and suspended in a shift reagent (SR) free medium, the extracellular 13'Cs+ NMR resonance was shifted upfield from the intracellular resonance. However, in the presence of the SRs Dy(PPP);-, Dy- (TTHA))-, and Tm(DOTP)S- [where Dy3+ and Tm3' denote dysprosium and thulium ions and PPPs-, TTHA6, and DOTPsrepresent the triphosphate, triethylenetetraminehexaacetate, a...
