## Abstract Differences in the NMR detectability of ^39^K in various excised rat tissues (liver, brain, kidney, muscle, and testes) have been observed. The lowest NMR detectability occurs for liver (61 Β± 3% of potassium as measured by flame photometry) and highest for erythrocytes (100 Β± 7%). These

## Abstract The hyperfine shift reagent, TmDOTP^5βˆ’^, was used to resolve the ^39^K NMR resonances of intra‐ (K~i~^+^) and extracellular (K~e~^+^) potassium in isolated, perfused guinea pig hearts. [K~i~^+^] as measured by ^39^K NMR was 25.9 Β± 10.3 mM, compared with 114.4 Β± 10.8 mM as measured by at
