MetabolomicsDetermination of Abundant Metabolite Matrix Adducts Illuminates the Dark Metabolome of MALDI-Mass Spectrometry Imaging Datasets
Spatial metabolomics using mass spectrometry imaging (MSI) is a powerful tool to map hundreds to thousands of metabolites in biological systems. One major challenge in MSI is the annotation of m/z values, which is substantially complicated by background ions introduced throughout the c...

MetabolomicsAssessing the potential of sputtered gold nanolayers in mass spectrometry imaging for metabolomics applications (Brain MALDI-MSI assay)

Mass spectrometry imaging (MSI) is a molecular imaging technique that maps the distribution of molecules in biological tissues with high spatial resolution. The most widely used MSI modality is matrix-assisted laser desorption/ionization (MALDI), mainly due to the large variety of analyte classes...

MetabolomicsSpatial metabolomics of in situ, host-microbe interactions (MALDI imaging 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 ...

MetabolomicsSingle-cell lipidomic analysis of the Epithelial-Mesenchymal Transition (EMT) using MALDI-MSI

EMT is a metastasis-promoting process whose heterogeneity has been extensively studied at a gene expression level. EMT also involves reprogramming of lipid metabolism, however there has been little focus on heterogeneity on the lipid level. Here, we use MALDI-MSI to determine the levels of variou...

ProteomicsTissue protease activity with MALDI MSI
Aberrant protease activity has been implicated in the etiology of various prevalent diseases including neurodegeneration and cancer, in particular metastasis. Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) has recently been established as a key technology for bio...

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...

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 ...
