Default Relaxation editing vr paramagnetic relaxation enhancement experiments - 13C CP-MAS NM

Relaxation editing vr paramagnetic relaxation enhancement experiments - 13C CP-MAS NMR

I am a beginner in NMR spectroscopy and I would like to learn more about relaxation editing experiments vs PRE. A colleague of mine is doing the 13C CP-MAS NMR experim. and he using cellulose II powder, regenerated cellulose and milled reg cellulose. We are interested in C4 resonance of cellulose II, good resolved resonance, to better understand the supramolecular structure of cellulose II. As experiments: long relaxation experiments - PRE with aqueous CuSO4 solution of certain concentration, does the CuSO4 sol conc has any effect on the experim? What is the difference between relaxation editing experiments and PRE?Thank you for your help.

Paramagnetic relaxation enhancement to improve sensitivity of fast NMR methods: application to intrinsically disordered proteins
Paramagnetic relaxation enhancement to improve sensitivity of fast NMR methods: application to intrinsically disordered proteins Abstract We report enhanced sensitivity NMR measurements of intrinsically disordered proteins in the presence of paramagnetic relaxation enhancement (PRE) agents such as Ni2+-chelated DO2A. In proton-detected 1H-15N SOFAST-HMQC and carbon-detected (H-flip)13CO-15N experiments, faster longitudinal relaxation enables the usage of even shorter interscan delays. This results in higher NMR signal intensities per units of experimental time, without adverse line...

Automated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methylâ??methyl nuclear overhauser enhancement spectroscopy
Automated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methylâ??methyl nuclear overhauser enhancement spectroscopy Abstract Methyl-transverse relaxation optimized spectroscopy is rapidly becoming the preferred NMR technique for probing structure and dynamics of very large proteins up to ~1 MDa in molecular size. Data interpretation, however, necessitates assignment of methyl groups which still presents a very challenging and time-consuming process. Here we demonstrate that, in combination with a known 3D structure, paramagnetic...
