Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 800-828, July/August 2026.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 829-850, July/August 2026.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

SPROUTS_DB: An Implemented Database of Contaminants for Extracellular Vesicle Proteomics Studies

PROTEOMICS, Volume 26, Issue 7, Page 69-83, July 2026.
ABSTRACT Current proteomics techniques allow rapid identification and quantification of proteins within any given biological source. However, LC–MS/MS proteomics is vulnerable to laboratory and sample‐associated contaminants. Therefore, accurate identification and annotation of such contaminants is crucial for development of reliable databases ...

Direct Competitive Kinetic Isotope Effect Measurement Using Quantitative Whole Molecule Matrix‐Assisted Laser Desorption Ionization Time‐of‐Flight Mass Spectrometry

ChemBioChem, Volume 27, Issue 12, 26 June 2026.
Kinetic Isotope effect (KIE) measurements are a powerful tool to interrogate enzyme mechanisms and transition state structures. In this study, we develop a simple quantitative MALDI‐TOF mass spectrometry approach to measure competitive heavy atom KIEs.
