Desorption electrospray ionization mass spectrometry reveals lipid metabolism of individual oocytes and embryos. [PDF]

PLoS ONE, 2013
Alteration of maternal lipid metabolism early in development has been shown to trigger obesity, insulin resistance, type 2 diabetes and cardiovascular diseases later in life in humans and animal models. Here, we set out to determine (i) lipid composition

Relative affinity constants by electrospray ionization and Fourier transform ion cyclotron resonance mass spectrometry: calmodulin binding to peptide analogs of myosin light chain kinase [PDF]

, 2003
Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca2+.

Carbon‐Encapsulated Gemini Ionic Liquid as Advanced Bromine Hosts for High‐Performance Zn–Br2 Batteries

Angewandte Chemie, EarlyView.
Rapid self‐discharge limits the practical deployment of Zn–Br2 batteries. Herein, a gemini ionic liquid featuring dual bromine‐binding sites and an aromatic linker is confined within porous carbon electrodes. The ionic liquid simultaneously complexes bromine species and interacts strongly with the carbon matrix, enabling efficient bromine retention ...
