High sensitivity high-resolution full range relaxometry using a fast mechanical sample shuttling device and a cryo-probe
Abstract
Field-dependent NMR studies of bio-molecular systems using a sample shuttling hardware operating on a high-field NMR apparatus have provided valuable structural and dynamic information. We have recently published a design of a compact sample transportation device, called â??field-cyclerâ??, which was installed in a commercial spectrometer and which provided highly precise positioning and stability during high speed...

Nitrogen-detected TROSY yields comparable sensitivity to proton-detected TROSY for non-deuterated, large proteins under physiological salt conditions
Nitrogen-detected TROSY yields comparable sensitivity to proton-detected TROSY for non-deuterated, large proteins under physiological salt conditions
Abstract
Direct detection of the TROSY component of proton-attached 15N nuclei (15N-detected TROSY) yields high quality spectra with high field magnets, by taking advantage of the slow 15N transverse relaxation. The slow transverse relaxation and narrow line width of the 15N-detected TROSY resonances are expected to compensate for the inherently low 15N sensitivity. However, the sensitivity of...

Abstract
Detection of (15)N in multidimensional NMR experiments of proteins has sparsely been utilized because of the low gyromagnetic ratio (?) of nitrogen and the presumed low sensitivity of such experiments. Here we show that selecting the TROSY...

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...

High resolution NMR spectroscopy of nanocrystalline proteins at ultra-high magnetic field
High resolution NMR spectroscopy of nanocrystalline proteins at ultra-high magnetic field
Abstract Magic-angle spinning (MAS) solid-state NMR (SSNMR) spectroscopy of uniformly-13C,15N labeled protein samples provides insight into atomic-resolution chemistry and structure. Data collection efficiency has advanced remarkably in the last decade; however, the study of larger proteins is still challenged by relatively low resolution in comparison to solution NMR. In this study, we present a systematic analysis of SSNMR protein spectra acquired at 11.7, 17.6 and 21.1 Tesla (1H frequencies of...

High resolution 13C-detected solid-state NMR spectroscopy of a deuterated protein
High resolution 13C-detected solid-state NMR spectroscopy of a deuterated protein
Abstract High resolution 13C-detected solid-state NMR spectra of the deuterated beta-1 immunoglobulin binding domain of the protein G (GB1) have been collected to show that all 15N, 13Câ?², 13Cα and 13Cβ sites are resolved in 13Câ??13C and 15Nâ??13C spectra, with significant improvement in T 2 relaxation times and resolution at high magnetic field (750 MHz). The comparison of echo T 2 values between deuterated and protonated GB1 at various spinning rates and under different decoupling schemes indicates...
