Preparing samples for DNP experiments sometimes involves using sedimented solutes. This is a nice overview of the technique and how it is beneficial for DNP-NMR spectroscopy.

Abstract
Solid-state NMR studies of sedimented soluble proteins has been developed recently as an attractive approach for overcoming the size limitations of solution NMR spectroscopy while bypassing the need for sample crystallization or precipitation (Bertini et al. Proc Natl Acad Sci USA 108(26):10396â??10399, 2011). Inspired by the potential benefits of this method, we have investigated the ability to sediment lipid bilayer...

[Question from NMRWiki Q&A forum] bigger MAS-NMR spectrum as irradiation window
bigger MAS-NMR spectrum as irradiation window
Hi,
I have a sample with a very very big CSA which is broader than my irradiation windows, so I have to acquire my data in 2 or more experiments (shaped pulses are enough and I can't go for another probehead). I need to do a simulation of the resulting spectrum, but I have to make sure my irradiation power is the same everywhere so the resulting sum spectrum isn't distorted. I heard about an article about how to choose the different irradiation windows of each measure so the sum still can be simulated but I couldn't get the source. I...

Solid-state NMR of proteins sedimented by ultracentrifugation [Chemistry]
Solid-state NMR of proteins sedimented by ultracentrifugation
Bertini, I., Luchinat, C., Parigi, G., Ravera, E., Reif, B., Turano, P....
Date: 2011-06-28
Relatively large proteins in solution, spun in NMR rotors for solid samples at typical ultracentrifugation speeds, sediment at the rotor wall. The sedimented proteins provide high-quality solid-state-like NMR spectra suitable for structural investigation. The proteins fully revert to the native solution state when spinning is stopped, allowing one to study them in both conditions. Transiently sedimented proteins can be considered a...

G protein-coupled receptors (GPCRs) represent one of the major targets of new drugs on the market given their roles as key membrane receptors in many cellular signalling pathways. Structure-based drug design has potential to be the most reliable method for novel drug discovery....
