Journal Highlight: Water proton NMR for in situ detection of insulin aggregates

Date: Jan 4, 2016

Author: spectroscopyNOW

Human insulin preparations were used to demonstrate that the transverse relaxation rate of water protons can serve as a sensitive and reliable indicator to detect and quantify both visible and sub-visible protein aggregates.

Ionic liquids: Enzymatic cellulose processing

Date: Dec 1, 2015

Author: David Bradley

The promise of room temperature ionic liquids (RTILs) as alternatives to toxic and inflammable volatile organic solvents for green chemistry has been on the boil for at least a couple of decades. Now, team has found that enzymatic activity can be sustained in processing cellulose, from wood, for conversion of this raw material into other useful compounds.

Journal Highlight: Single-scan multidimensional NMR analysis of mixtures at sub-millimolar concentrations by using SABRE hyperpolarization

Date: Nov 30, 2015

Author: spectroscopyNOW

An approach to obtain clean, SABRE-hyperpolarized 2D 1H NMR spectra of mixtures of small molecules at sub-mM concentrations in a single scan uses para-hydrogen and a deuterated co-substrate for hyperpolarization and ultrafast 2D NMR for acquisition.

Into the fold: Sensitivity-enhanced NMR

Date: Oct 15, 2015

Author: David Bradley

Researchers at Massachusetts Institute of Technology have used sensitivity-enhanced nuclear magnetic resonance (NMR) spectroscopy to analyse the structure that a yeast protein forms as it interacts with other proteins in a cell opening up new insights into protein folding and misfolding.
