Extracting the urine: NMR tells us more

Date: Sep 15, 2019

Author: David Bradley

A rapid and quantitative aproach to metabolite analysis of urine samples has been taken by a tea from Aaurhus University, Sweden who use a paramagnetic co-solute in their nuclear magnetic resonance (NMR) spectroscopy.

Journal Highlight: Minimizing the risk of deducing wrong natural product structures from NMR data

Date: Sep 5, 2019

Author: spectroscopyNOW

This tutorial highlights the kinds of errors that have been made in NMR structural interpretation in the literature and provides specific advice on how to avoid the mistakes that risk reporting a wrong structure.

Glucagon fibrils: NMR looks at insulin counterpart

Date: Aug 15, 2019

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has revealed to scientists at Massachusetts Institute of Technology (MIT) how glucagon the hormonal counterpart to insulin has a structure unlike other known amyloid fibrils. The discovery might one day lead to an alternative way to control Type 1 diabetes.

Journal Highlight: Effect of autoclaving on the mechanical properties and structure of the giant squid hydrolysate‐polysaccharide gel

Date: Jul 31, 2019

Author: spectroscopyNOW

The effects of autoclaving treatment on the microstructure and properties of the giant squid hydrolysate‐konjac glucomannan‐κ‐carrageenan‐locust bean gum gel have been studied by NMR, rheology measurements, confocal laser scanning microscopy and small‐angle X‐ray scattering.

Addressing precession: The coming NMR revolution

Date: Jul 15, 2019

Author: David Bradley

A new approach to nuclear magnetic resonance (NMR) spectroscopy has been developed by researchers at ETH Zurich led solid-state physicist Christian Degen. The method allows the precession of single nuclear spins to be tracked individually. This could revolutionise NMR given that measurements usually need at least 1012 atomic nuclei to produce a measurable signal.

Journal Highlight: Observing an antisense drug complex in intact human cells by in‐cell NMR

Date: Jul 4, 2019

Author: spectroscopyNOW

The interactions of an untagged antisense oligonucleotide drug delivered into HEK293T and HeLa cells have been studied by in-cell NMR using a combination of transfection, cryoprotection and dynamic nuclear polarization.

Live view: NMR in a eukaryotic cell

Date: Jun 15, 2019

Author: David Bradley

The three-dimensional structure of a protein within a living higher eukaryotic cell can be obtained using nuclear magnetic resonance (NMR) spectroscopy and computational methods, according to research from Tokyo published in Angewandte Chemie.
