Structural damage: Analyzing heparin with CE-MS

Date: Feb 15, 2016

Author: Jon Evans

A novel CE-MS method for analyzing the molecular structure of the anticoagulant heparin should help prevent the severe allergic reactions that led to many deaths several years ago.

The weakest linker: Testing the stability of novel DNA structures

Date: Jan 18, 2016

Author: Jon Evans

Investigating the properties of various different linkers for constructing novel DNA structures required German chemists to use gel electrophoresis at almost every stage in the process.

Solving a sticky problem: How to separate proteins that stick to capillary walls

Date: Dec 21, 2015

Author: Jon Evans

The propensity of proteins to stick to capillary walls causes less of a problem for micro free flow electrophoresis than for capillary electrophoresis, say US chemists.

Journal Highlight: Development and comparison of a generic multiple-locus variable-number tandem repeat analysis with pulsed-field GE for typing of Salmonella enterica subsp. enterica

Date: Dec 14, 2015

Author: separationsNOW

Danish food scientists have developed a new method for typing different strains of Salmonella that is at least as good as pulsed-field gel electrophoresis.

Buzzing around proteomics data: Studying mosquito proteins with 2D gel electrophoresis

Date: Nov 16, 2015

Author: Jon Evans

A proteomic and metabolomic study into how malaria-transmitting mosquitoes survive the dry season in West Africa has generated too much data for just one journal paper.
