Default High sensitivity high-resolution full range relaxometry using a fast mechanical sample shuttling device and a cryo-probe

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 ??field-cycler??, which was installed in a commercial spectrometer and which provided highly precise positioning and stability during high speed shuttling. In this communication, we demonstrate the first use of a sample shuttling device on a commercial high field standard bore NMR spectrometer, equipped with a commercial triple resonance cryogenically cooled NMR probe. The performance and robustness of the hardware operating in 1D and 2D field cycling experiments, as well as the impact of the sample shuttling time on the signal intensity are discussed.

Nitrogen detected TROSY at high field yields high resolution and sensitivity for protein NMR
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 (>600*MHz) by taking advantage of the slow 15N transverse relaxation and compensating for the inherently low...

Sensitivity gains, linearity, and spectral reproducibility in nonuniformly sampled multidimensional MAS NMR spectra of high dynamic range
Sensitivity gains, linearity, and spectral reproducibility in nonuniformly sampled multidimensional MAS NMR spectra of high dynamic range Abstract Recently, we have demonstrated that considerable inherent sensitivity gains are attained in MAS NMR spectra acquired by nonuniform sampling (NUS) and introduced maximum entropy interpolation (MINT) processing that assures the linearity of transformation between the time and frequency domains. In this report, we examine the utility of the NUS/MINT approach in multidimensional datasets possessing high...

High-resolution NMR field-cycling device for full-range relaxation and structural studies of biopolymers on a shared commercial instrument
High-resolution NMR field-cycling device for full-range relaxation and structural studies of biopolymers on a shared commercial instrument Abstract Improvements are described in a shuttling field-cycling device (Redfield in Magn Reson Chem 41:753??768, 2003), designed to allow widespread access to this useful technique by configuring it as a removable module to a commercial 500 MHz NMR instrument. The main improvements described here, leading to greater versatility, high reliability and simple construction, include: shuttling provided by a linear motor driven by an integrated-control...
