To better conduct the analysis of nucleoside analogues, hydrophilic interaction liquid chromatography–tandem mass spectrometry (HILIC-MS/MS) was used to quantify antitumor prodrugs and their metabolites.

In episode #37 of Analytically Speaking, podcast host Dr. Jerry Workman speaks with Dr. Austin Daniels, application scientist for Yokogawa Fluid Imaging Technologies, about flow imaging microscopy (FIM), a new technology for sub-visible particle characterization in biologics.

A study from Justus Liebig University Giessen presents a novel, cost-effective method for evaluating the safety of personal care products using high-performance thin-layer chromatography (HPTLC) combined with planar bioassays.

John Yates’ lab is using MOBILion’s Parallel Accumulation Mobility Aligned Fragmentation (PAMAF) technology to enhance the DeGlyPHER workflow, which enables detailed, site-specific analysis of N-glycosylation in viral spike proteins such as SARS-CoV-2. This method combines sequential deglycosylation with high-sensitivity LC-MS to quantify glycan occupancy and processing, offering insights into the relationship between glycosylation and immune response. DeGlyPHER has been applied to over 200 vaccine candidates, including those for HIV, influenza, and Ebola, advancing understanding of glycoprotein-based immunogen design. This executive summary explains how DeGlyPHER is transforming vaccine development in real time, driving progress toward more effective and consistent immunization strategies, and delivering a more sensitive and high-throughput approach compared to traditional glycoproteomic methods.

Using two-dimensional liquid chromatography–mass spectrometry, a new workflow was developed to characterize phosphorodiamidate morpholino oligomers, which can help treat infectious diseases.
