The low sensitivity of NMR spectroscopy is of historical concern in the field, and various approaches have been developed to mitigate this limitation. On the shoulder of giants, today one can routinely implement, for example, the pulse/Fourier transform NMR with the cross polarization together with the ultra-low temperature MAS DNP under high-field conditions. We show in this work this current opportunity should further be augmented by combining them with the cryogenic signal amplification. Our...

Nitrogen detected TROSY at high field yields high resolution and sensitivity for protein NMR
Abstract
Detection of 15N in multidimensional NMR experiments of proteins has sparsely been utilized because of the low gyromagnetic ratio (γ) of nitrogen and the presumed low sensitivity of such experiments. Here we show that selecting the TROSY components of proton-attached 15N nuclei (TROSY 15NH) yields high quality spectra in high field magnets (>600Â*MHz) by taking advantage of the slow 15N transverse relaxation and compensating for the inherently low...
