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.

Cyclic peptides, known for their stability and high specificity, are promising therapeutic agents in the fight against cancer, infections, and autoimmune diseases. However, developing effective cyclic peptides presents numerous challenges, including poor pharmacokinetics, efficacy, and toxicity. Traditional methods like liquid chromatography tandem-mass spectrometry (LC-MS/MS) often struggle with resolving isomeric linear peptide metabolites, posing significant risks in safety, efficacy, and regulatory approval. In this paper, Komal Kedia, PhD, will share how she leveraged MOBIE’s high-resolution ion mobility-mass spectrometry (IM-MS) system to achieve a 72% reduction in run times, 200% greater resolving power, and enhanced accuracy in identifying “soft spots” prone to enzymatic degradation.

MOBILion has introduced a new high-resolution mass spectrometry (HRMS) approach that can increase speed and sensitivity in omics applications. The parallel accumulation with mobility aligned fragmentation (PAMAF) approach substantially increases the fraction of ions used for MS analysis by replacing the functionality of the quadrupole with high-resolution ion mobility.

In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
