Sensitivity Enhancement in (13)C Solid-State NMR of Protein Microcrystals by Use of Paramagnetic Metal Ions for Optimizing (1)H T(1) Relaxation

We discuss a simple approach to enhance sensitivity for (13)C high-resolution solid-state NMR for proteins in microcrystals by reducing (1)H T(1) relaxation times with paramagnetic relaxation reagents. It was shown that (1)H T(1) values can be reduced from 0.4-0.8 s to 60-70 ms for ubiquitin and lys...
