MetabolomicsAnalysis of colorectal adenocarcinoma tissue samples by DESI mass spectrometry imaging
Ex vivo colorectal adenocarcinoma samples were analysed by desorption electrospray ionisation using an Orbitrap mass spectrometer. The samples were analysed in negative mode over the m/z range 600-1000. Some of the samples presented in this dataset were analysed as part of [1]. The study makes avail...

MetabolomicsSpatial metabolomics of in situ, host-microbe interactions (On-tissue MALDI imaging MS/MS assay)
Spatial metabolomics describes the location and chemistry of small molecules involved in metabolic phenotypes, defense molecules and chemical interactions in natural communities. Most current techniques are unable to spatially link the genotype and metabolic phenotype of microorganisms in situ at a ...

MetabolomicsAutomated, Parallel Mass Spectrometry Imaging and Structural Identification of Lipids
We report a method that enables automated data-dependent acquisition of lipid tandem mass spectrometry data in parallel with a high-resolution mass spectrometry imaging experiment. The method does not increase the total image acquisition time and is combined with automatic structural assignment. Thi...

MetabolomicsDESI mass spectrometry imaging of murine tissues

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

MetabolomicsFDR-controlled metabolite annotation for high-resolution imaging mass spectrometry - simulated Imaging MS (Imaging simulation assay)
High-mass-resolution imaging mass spectrometry promises to localize hundreds of metabolites directly from tissues, cell cultures, and agar plates with cellular resolution, but is hampered by the lack of bioinformatics for automated metabolite identification. We developed the first bioinformatics fra...

MetabolomicsBenchmark datasets for 3D MALDI- and DESI-Imaging Mass Spectrometry
Three-dimensional imaging mass spectrometry (3D imaging MS) is a technique of analytical chemistry for 3D molecular analysis of a tissue specimen, entire organ, or microbial colonies on an agar plate. 3D imaging MS has unique advantages over existing 3D imaging techniques, offers novel perspectives ...

MetabolomicsmassPix: An R package for annotation and interpretation of mass spectrometry imaging data for lipidomics
Mass spectrometry imaging (MSI) experiments result in complex multi-dimensional datasets, which require specialist data analysis tools. Here we have developed massPix - an R package for analysing and interpreting data from MSI of lipids in tissue. MassPix is an open-source tool for the analysis and ...

MetabolomicsMass Spectrometry Imaging of Lipids in a Gut Epithelial Cell Model

Scope: The Caco2/HT29-MTX co-culture system is widely used as a cell model of the intestinal epithelium. Although the gut epithelium plays an important role in the uptake of free fatty acids and the resynthesis of triglycerides, the lipid distribution profile of the two-dimensional co-culture sys...

MetabolomicsNovel automated workflow for spectral alignment and mass calibration in MS imaging using a sputtered Ag nanolayer
Mass spectrometry imaging (MSI) is a technique that can map analyte spatial distribution directly onto a tissue section. This enables the spatial correlation of molecular entities with a tissue morphology to be investigated. Analyte annotation in MSI is intrinsically linked to the mass accuracy of t...
