MALDI mass spectrometry imaging stands as a pivotal technology for unraveling the spatial distribution of biomarkers, metabolites, pharmaceuticals, and xenobiotics in tissue sections.

**MALDI-qMSI (Matrix-Assisted Laser Desorption/Ionization Quantitative Mass Spectrometry Imaging)** is a technique that combines MALDI with mass spectrometry imaging to analyze and map the spatial distribution of molecules within a sample. It provides both qualitative and quantitative data about the molecular composition and concentration across the sample's surface. This method is particularly useful in biological and clinical research for studying tissues, analyzing drug distribution, and investigating disease-related molecular changes.

Pharmacological inhibition of MERTK induces in vivo retinal degeneration: a multimodal imaging ocular safety assessment | 2022

We have applied a state-of-the-art, multi-modal imaging platform to assess the in vivo effects of pharmacological inhibition of MERTK in mice. This involved the application of mass spectrometry imaging (MSI) to characterize the ocular spatial distribution of our highly selective MERTK inhibitor; AZ14145845, together with histopathology and transmission electron microscopy to characterize pathological and ultra-structural change in response to MERTK inhibition.

Application note: Deposition of reference standards on tissues for quantitative MALDI mass spectrometry imaging | 2021

Quantitative matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI qMSI) has become a very powerful tool to reveal the spatial distribution of biomolecules and xenobiotics in tissue sections. Especially in pharmaceutical research it is increasingly used for analysis of drug and metabolite distribution as well as in pharmacodynamic biomarker research and toxicology. In this application note we describe how a reliable disposal of standards is achieved by means of the BIOSPOT® nanoliter liquid handling workstation.

We are thankful to our colleagues at NUVISAN for sharing these data and the collaboration to establish automated solutions for the qMSI workflow!

Neuropharmacokinetic visualization of regional and subregional unbound antipsychotic drug transport across the blood–brain barrier | 2021

Comprehensive determination of the extent of drug transport across the region-specific blood–brain barrier (BBB) is a major challenge in preclinical studies. Multiple approaches are needed to determine the regional free (unbound) drug concentration at which a drug engages with its therapeutic target. We present an approach that merges in vivo and in vitro neuropharmacokinetic investigations with mass spectrometry imaging to quantify and visualize both the extent of unbound drug BBB transport and the post-BBB cerebral distribution of drugs at regional and subregional levels.

Evaluation of UV‑C Decontamination of Clinical Tissue Sections for Spatially Resolved Analysis by Mass Spectrometry Imaging (MSI) | 2021

Clinical tissue specimens are often unscreened, and preparation of tissue sections for analysis by mass spectrometry imaging (MSI) can cause aerosolization of particles potentially carrying an infectious load. We here present a decontamination approach based on ultraviolet-C (UV-C) light to inactivate clinically relevant pathogens such as herpesviridae, papovaviridae human immunodeficiency virus, or SARS-CoV-2, which may be present in human tissue samples while preserving the biodistributions of analytes within the tissue.
