2023 article
Lipidomic Analysis of Mouse Brain to Evaluate the Efficacy and Preservation of Different Tissue Preparatory Techniques by IR-MALDESI-MSI
Wang, M. F., Sohn, A. L., Samal, J., Erning, K., Segura, T., & Muddiman, D. C. (2023, March 29). JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY, Vol. 3.
author keywords: IR-MALDESI; mass spectrometry imaging; sucrose; PFA
MeSH headings : Mice; Animals; Spectrometry, Mass, Electrospray Ionization / methods; Lipidomics; Ice; Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization / methods; Ions / chemistry; Lipids / analysis; Brain
TL;DR:
Evidence from these investigations supports sucrose-embedding without ice matrix as an alternative preparatory technique for IR-MALDESI-MSI, and demonstrates improved spatial distribution of ions resulting from the cryo-protective property of sucrose and paraformaldehyde fixation.

Interrogating the Metabolomic Profile of Amyotrophic Lateral Sclerosis in the Post-Mortem Human Brain by Infrared Matrix-Assisted Laser Desorption Electrospray Ionization (IR-MALDESI) Mass Spectrometry Imaging (MSI)
METABOLITES, 12(11).
author keywords: IR-MALDESI MSI; mass spectrometry imaging; Amyotrophic lateral sclerosis (ALS); neurodegenerative disease; multiomic
TL;DR:
This work is the first of its kind, reporting on the investigation of ALS post-mortem human brain tissue analyzed by multiomic MSI, and nearly 300 metabolites were identified across the sixteen samples where 25 were identified as dysregulated between disease cohorts.
