Enhanced Detection of Charged N-Glycans in the Brain by Infrared Matrix-Assisted Laser Desorption Electrospray Ionization Mass Spectrometric Imaging

ANALYTICAL CHEMISTRY, 95(29), 10913–10920.

By: J. Samal*, T. Palomino n, J. Chen*, D. Muddiman n & T. Segura*

TL;DR: This work demonstrates the first application of IR-MALDESI in N-linked glycan imaging of the brain tissue, leading to a 2.5-fold increase in the in situ total brain N-glycan detection compared to the current gold standard of positive-mode matrix-assisted laser desorption/ionization mass spectrometry imaging.

Predicting Sialic Acid Content of N-Linked Glycans Using the Isotopic Pattern of Chlorine

Palomino, T. V., & Muddiman, D. C. (2023, June 8). JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY, Vol. 6.

By: T. Palomino n & D. Muddiman n

author keywords: N-linked glycans; sialic acid; chlorine; IR-MALDESI
MeSH headings : Humans; N-Acetylneuraminic Acid; Chlorine; Polysaccharides / chemistry; Sialic Acids / analysis; Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization / methods
TL;DR: A new rule is described that can predict the number of sialic acids on a glycan and grants confident glycan annotations and compositions beyond accurate mass measurements, thereby further improving the capability of IR-MALDESI to study sialylated N-linked glycans within biological tissues.
