INTRODUCTION: Mass spectrometry based metabolomics has become a promising complement and alternative to transcriptomics and proteomics in many fields including in vitro systems pharmacology. Despite several merits, metabolomics based on liquid chromatography mass spectrometry (LC...
Detailed characterization of complex biological surfaces by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) requires instrumentation that is capable of high mass resolving power, mass accuracy and dynamic range. Fourier transform ion cyclotron resonance mass sp...
RATIONALE: There is increasing interest in methods of direct analysis mass spectrometry that bypass complex sample preparation steps.
METHODS: One of the most interesting new ionisation methods is rapid evaporative ionisation mass spectrometry (REIMS) in wh...
Analysis of bacterial composition using rapid evaporative ionisation mass spectrometry (REIMS) allows for the detection of metabolites that may be considered specific to particular taxons. This database of 3274 isolates covering gram positive and negative bacteria across 5 phyla, 12 classes, 24 o...
DESI-MS imaging results of a murine colorectal tumour tissue, a murine jejunum tissue and a Helicobacter pylori-infected murine stomach tissue are available. Data were all obtained under negative ion mode. Corresponding H&E staining results can be found in the associated publication
One of the major bottlenecks in describing marine ecosystems is characterizing the metabolome of seawater, as salt prevents metabolite analysis. We present SeaMet, a method that can detect hundreds of metabolites in less than one ml of seawater and quantifies them down to nano-molar levels using ...
