Researchers combine a single-probe single cell mass spectrometry technique with a bioinformatics software package to quantify cell subpopulations and prioritize metabolite biomarkers, providing a label-free approach to studying cell heterogeneity and improving understanding of cell metabolism in human diseases and response to therapy.

Researchers have developed a PAMAM-functionalized paper substrate that boosts the sensitivity of protein analysis by paper spray mass spectrometry (PS-MS), potentially revolutionizing clinical diagnosis of diseases.

This article compares the performance of wide-pore silica monolithic, sub-2µm FPP, and SPP columns, addresses the question of whether 1000 Å or 400 Å SPP columns are more suitable for reversed-phase LC-type protein separations, and presents a kinetic performance comparison of different columns.

A micro-pillar array format for mapping the proteome of human stem cell-derived liver organoids using timsTOF–MS is presented.

A new fragmentation approach—tunable electron-activated dissociation (EAD) tandem mass spectrometry (MS/MS)—offers a solution to better improve the detection and characterization of impurities in lipid nanoparticles and impurities in other biopharmaceutical modalities.

The combination of an untargeted approach using ultrahigh pressure liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC–QTOF) and a targeted approach using UHPLC–tandem mass spectrometry (MS/MS) are presented as an ideal method for detecting per- and polyfluroalkyl substances (PFAS) in fast-food packaging.

By modifying polyniobate on a metal-organic framework, scientists have managed to purify Cytochrome C for proteomic analysis using LC–MS/MS.

Carol V. Robinson of the University of Oxford has been named the 2023 recipient of the ASMS John B. Fenn Award for Distinguished Contribution in Mass Spectrometry. Robinson will receive the award at the 2023 ASMS Conference in Houston, Texas, which takes place June 4–8.

What is the right number of replicates in biopharmaceutical analysis? Does the answer depend on the type of analysis?

Pepsin digestion and guanidine hydrochloride post-digestion can improve sequence coverage in antibody peptide mapping compared with trypsin digestion.

In response to regulatory concerns, host cell protein (HCP) analysis is now often conducted using LC–MS/MS. Unlike ELISA, LC–MS/MS can positively identify and quantify specific HCPs and characterize the total amount of HCPs present.

To reach satisfactory results in terms of accurate retention time prediction, new in silico optimization approaches must be considered.
