Microplastics and Nanomaterials: Understanding Emerging Contaminants in Environmental Testing

🎤Matthew BolinoHow do the hidden carbohydrate structures on your favorite protein powders shape the gut microbiome? &nbsp;In this episode of Concentrating on Chromatography, Matthew Bolino, M.S., from the University of Nevada, Reno, breaks down his latest research on N‑glycans from common dietary proteins (whey, egg white, soy, and pea) and how their structural diversity influences microbial fermentation and short‑chain fatty acid production.Bolino explains what N‑glycans are, why they behave like fiber in the gut, and how his team isolates and characterizes them using ethanol washes, enzymatic release (PNGase F and gut‑derived endoglycosidases), and advanced MALDI‑TOF and HILIC‑QTOF workflows. &nbsp;He also discusses his 2025 work comparing synthetic versus bovine whey N‑glycomes and mapping N‑glycan profiles across dietary protein sources, revealing how glycan architecture can reshape community diversity in in vitro fecal fermentations.Geared toward undergraduate and early‑career analytical chemists, this conversation dives into practical mass spec trade‑offs (MALDI vs QTOF vs LC/GC), real‑world troubleshooting in glycomics labs, and how microbiome‑targeted therapeutics and “symbiotic” designs may emerge from pairing specific microbes with preferred glycan structures. &nbsp;Bolino closes with career advice on building biomolecular analysis skills, understanding instrumentation fundamentals, and entering the rapidly growing field of glycomics and microbiome research.<h3>Video Transcription</h3><h4>Introduction</h4>Glycomics has emerged as a rapidly developing field within biomolecular science, expanding our understanding of post-translational modifications beyond well-known processes such as phosphorylation. Among these modifications, protein glycosylation—the covalent attachment of carbohydrate structures to proteins—plays a critical role in biological function, molecular recognition, and cellular communication.This discussion focuses on N-glycans, a class of structurally complex carbohydrates linked to proteins, and their occurrence in common dietary protein sources such as whey, egg white, soy, and pea protein. Particular emphasis is placed on their structural diversity, analytical workflows, and emerging relevance in gut microbiome research.<h4>Fundamentals of N-Glycans</h4>N-glycans are oligosaccharide structures covalently attached to proteins via nitrogen atoms, typically at asparagine residues. They represent one of the two major classes of protein glycosylation, alongside O-glycans.These glycans are characterized by:<ul><li>High structural diversity, arising from variations in monosaccharide composition and linkage patterns</li><li>Large size, typically comprising 7–15 monosaccharide units</li><li>Complex branching architectures, leading to a vast number of possible configurations</li></ul>Common monosaccharide components include:<ul><li>Mannose</li><li>Galactose</li><li>N-acetylglucosamine</li><li>N-acetylgalactosamine</li><li>Sialic acids</li></ul>Unlike free carbohydrates present in foods (e.g., glucose, lactose), N-glycans are protein-bound, which significantly influences their biological behavior.<h4>Biological Function and Dietary Relevance</h4>N-glycans play multiple roles in biological systems, including:<ul><li>Modulation of protein stability</li><li>Regulation of protein trafficking and localization</li><li>Facilitation of cell–cell communication and immune recognition</li></ul>They are particularly abundant on membrane and surface proteins, where they contribute to molecular signaling processes.From a dietary perspective, N-glycans exhibit unique behavior. Due to their size and protein-bound nature, they are not readily digested in the upper gastrointestinal tract. Instead, they can reach the colon, where they may function analogously to dietary fiber, interacting with the gut microbiota.<h4>Research Motivation</h4>The investigation of N-glycans in dietary proteins was initially driven by interest in protein nutrition and supplementation, particularly in the context of muscle growth and protein quality. However, this focus expanded upon recognition of the importance of glycosylation in biological systems.The field of glycomics offers:<ul><li>Extensive structural variability, enabling diverse biological functions</li><li>Relevance in disease mechanisms, including cancer, where glycosylation patterns can influence immune evasion</li><li>Opportunities to explore diet–microbiome interactions</li></ul>This combination of nutritional, biochemical, and biomedical relevance makes N-glycan research particularly compelling.<h4>Experimental Workflow for N-Glycan Analysis</h4>The analysis of N-glycans requires a multi-step workflow due to their covalent attachment to proteins.<h5>1. Protein Purification</h5>Dietary protein samples often contain:<ul><li>Free sugars</li><li>Lipids</li><li>Other matrix components</li></ul>To isolate glycoproteins:<ul><li>Cold ethanol precipitation is used to remove free carbohydrates</li><li>Multiple washing steps ensure removal of residual sugars</li><li>A phenol–sulfuric acid assay is applied to confirm the absence of free sugars</li></ul><h5>2. Enzymatic Release of N-Glycans</h5>N-glycans are enzymatically cleaved from proteins using:<ul><li>PNGase F (Peptide-N-Glycosidase F)</li></ul>This enzyme:<ul><li>Specifically cleaves the glycan from the protein backbone</li><li>Preserves the intact glycan structure</li></ul>Alternative approaches using gut-derived enzymes are being explored to improve accessibility and yield.<h5>3. Glycan Purification and Labeling</h5>Following release:<ul><li>Glycans are purified from the protein matrix</li><li>Chemical labeling is performed (e.g., 2-AA or procainamide tagging)</li></ul>Labeling enhances:<ul><li>Detection sensitivity</li><li>Chromatographic behavior</li></ul><h5>4. Analytical Techniques</h5>Two primary analytical platforms are employed:<ul><li>MALDI-TOF MS<ul><li>High sensitivity</li><li>Broad structural coverage</li></ul></li><li>HILIC-LC-MS<ul><li>Improved reproducibility</li><li>Enhanced chromatographic separation</li></ul></li></ul>These approaches provide semi-quantitative data, where signal intensity reflects relative abundance rather than absolute concentration.<h4>Analytical Challenges</h4>Several challenges are associated with N-glycan analysis:<h5>Low Abundance</h5><ul><li>Dietary proteins typically contain only 1–2% glycan content by weight</li><li>This limits yield and complicates downstream applications</li></ul><h5>Sample Preparation Complexity</h5><ul><li>Extensive purification is required to eliminate free sugars</li><li>Contamination risks must be carefully managed</li></ul><h5>Instrumentation Trade-Offs</h5><ul><li>Different analytical platforms offer complementary advantages</li><li>No single technique provides complete structural and quantitative information</li></ul><h4>Differences Between Plant and Animal N-Glycans</h4>Comparative analysis reveals distinct differences in glycan composition:<h5>Plant-Derived Proteins (e.g., soy, pea)</h5><ul><li>Predominantly high-mannose structures</li><li>Lower monosaccharide diversity</li><li>Simpler glycan architectures</li></ul><h5>Animal-Derived Proteins (e.g., whey, egg white)</h5><ul><li>Greater structural complexity</li><li>Inclusion of diverse monosaccharides (e.g., sialic acids)</li><li>More elaborate branching patterns</li></ul>These differences have important implications for biological function and microbial interactions.<h4>Implications for Gut Microbiome Research</h4>N-glycans represent a potential class of prebiotic substrates that can influence gut microbiota composition and activity.Key findings suggest:<ul><li>Structural diversity of glycans affects microbial utilization patterns</li><li>More complex glycans may promote greater microbiome diversity</li><li>Specific glycan structures may selectively stimulate beneficial microbes</li></ul>This has led to growing interest in:<ul><li>Synbiotic strategies, combining microbes with preferred substrates</li><li>Tailored dietary interventions to enhance metabolic outputs, such as short-chain fatty acids</li></ul><h4>Methodological Considerations</h4>A critical insight from this work is the importance of understanding analytical trade-offs:<ul><li>MALDI-TOF MS provides broader detection of glycan structures</li><li>LC-MS approaches offer greater reproducibility</li></ul>No single technique is universally optimal; instead, method selection should be guided by the specific research question.<h4>Conclusion</h4>N-glycans in dietary proteins represent a complex and biologically significant class of biomolecules with implications spanning nutrition, microbiology, and disease research. Advances in analytical methodologies continue to improve our ability to characterize these structures, despite challenges related to low abundance and structural diversity.A deeper understanding of N-glycan composition and function may enable the development of targeted nutritional strategies and microbiome-based therapeutics, highlighting the growing importance of glycomics in modern life sciences.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

N‑Glycans, Whey Protein, and the Gut Microbiome: Mass Spec Insights with Matthew Bolino

<div><div><div>Our immune system is incredibly powerful: among other things, it can recognize and destroy cancer cells. But tumors can be just as effective at avoiding detection – they build “invisibility shields” to protect themselves from attack.</div></div><div>One breakthrough in cancer therapy has been immune checkpoint inhibitors (ICIs), drugs that reactivate immune T cells and help them fight tumors again. However, only about 20–50% of patients respond well to this treatment. Researchers are therefore seeking alternative therapeutic strategies. A small and well-known molecule called adenosine plays a key role in these efforts.When tumor cells are stressed or dying, they release ATP, which is normally a signal that something is wrong in the tissue. But in the tumor microenvironment, ATP gets rapidly broken down by two enzymes, CD39 and CD73. Released adenosine acts like a chemical “calm-down” signal, binds to immune cells (T cells, NK cells, and others), and tells them to slow down, reducing their ability to kill cancer cells. Targeting CD73 therefore represents a promising strategy for developing new cancer treatments.</div><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Nove_latky_mohou_podporit_imunitni_system_v_boji_s_rakovinou_88c5e82cd5.jpeg" alt="IOCB Prague: Development of potent inhibitors to boost the immune system's ability to fight cancer" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Nove_latky_mohou_podporit_imunitni_system_v_boji_s_rakovinou_88c5e82cd5.jpeg 245w," sizes="100vw" width="661" height="363">At IOCB Prague, interdisciplinary teams led by Jan Řezáč, Jan Konvalinka, and Michal Hocek used a newly developed high-throughput screening method to test over 5,000 compounds, identifying two ribonucleoside derivatives as promising CD73 inhibitors.The scientists then improved the compounds’ activity by carefully modifying the ribonucleoside scaffold with bulky (het)aryl groups. Further optimization improved the pharmacokinetic properties of these compounds, yielding inhibitors with low clearance, long half-life, high solubility, and strong selectivity over related enzymes such as CD39.In cellular experiments, the compounds reduced adenosine production in cancer cells, restored T cell activation, and showed no toxicity toward human fibroblasts. The most active compound showed a single-digit picomolar inhibition constant (Ki).These findings establish a strong foundation for further in vivo efficacy and combination studies, which will explore the therapeutic potential of this novel inhibitor class.<blockquote><h4>The Original article</h4><h4><a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acsptsci.5c00707">Potent Competitive Inhibitors of Ecto-5′-nucleotidase (CD73) based on 6-(Het)aryl-7-deazapurine Ribonucleoside 5′-O-Bisphosphonates</a></h4>Ugnė Šinkevičiu̅tė, Magdalena Šímová, Radek Staník, Lenka Poštová Slavětínská, Kristýna Blažková, Pavel Šácha, Martin Lepšík, Jan Řezáč, Jan Konvalinka, Tereza Ormsby, Michal Tichý, Michal HocekACS Pharmacol.

We have designed and systematically studied diverse 2-substituted 7-deazapurine ribonucleoside 5′-O-bisphosphonates bearing a variety of (het)aryl groups at position 6 and discovered their highly potent and selective CD73 inhibition activity. The most active compounds (with single-digit picomolar Ki) contained bicyclic (het)aryl groups at position 6 in combination with chlorine at position 2. Further optimization of pharmacokinetic properties identified inhibitors with low clearance, long half-life, high solubility, and excellent selectivity over CD39 and NTPDase3. They effectively suppressed adenosine formation in MDA-MB-231 cells, rescued CD8+ T cell activation, and were nontoxic to human fibroblasts. Overall, their profile compares favorably with AB680, a CD73 inhibitor currently in phase I/II clinical trials.</div>

<h5>Talk 3: Analysis of NIST mAb Reference Material by Parallel SDS-Capillary Electrophoresis</h5>
<ul>
<li>Presented by Dr. Kyle Luttgeharm, Product Manager, Agilent Technologies</li>
</ul>
Monoclonal antibody drug products are complex biomolecules that must be tested for critical quality attributes (CQAs) such as monomeric purity and percent glycosylation. Capillary gel electrophoresis methods have been adopted as the standard method for size heterogeneity characterization, however legacy capillary electrophoresis (CE) methods involve complicated workflows or are cost prohibitive. To address these problems with legacy methods, Agilent has developed a 12-channel, parallel capillary electrophoresis-SDS (CE-SDS) instrument and reagents. The system uses a high-resolution sieving gel, allowing for resolution of mAb species including the non-glycosylated heavy chain and light chain. To demonstrate the capabilities of the ProteoAnalyzer, the NIST mAb was characterized under both reduced and non-reduced conditions and compared to the NIST data sheet.

<h5>Talk 2: Extracted Yeast tRNA Sequencing by LC-MS/MS</h5>
<ul>
<li>Presented by Aurore Attina, Engineer of Mass Spectrometry, University of Montpellier</li>
</ul>
RNA modifications are essential for RNA stability, maturation, and functionality; directly influencing protein translation and gene regulation. They play a central role in various biological processes and are associated with many diseases, including cancers and neurological disorders. tRNA (transfer RNA), which plays a key role in protein synthesis, is the most modified molecule in the organism known to date. tRNA modifications are essential to ensure their correct function in protein translation, maintain the accuracy and fidelity of the genetic code, and enable flexible adaptation to changing cellular conditions and are therefore a crucial attribute to monitor. To monitor and map these modifications of tRNA, we have developed a LC-HRMS analytical workflow, first using synthetic oligonucleotide for the method optimization. In this webinar, we will first go through the various steps involved in LC-MS/MS method optimization using synthetic oligonucleotides. In a second part, we will present the protocol development of an enzymatic digestion applied to tRNA extracted from yeast. This digestion generates oligonucleotide fragments that can be analyzed by LC-MS/MS for sequence confirmation.
<h5>Talk 3: Discover Agilent’s Software Tools to Confirm Oligonucleotide Sequence Integrity</h5>
<ul>
<li>Presented by Dr. Holger Stalz, LC/MS Product Specialist Austria &amp; Switzerland, Agilent Technologies</li>
</ul>
Mass spectrometry (MS) is increasingly important for the development of therapeutic modalities such as oligonucleotides. A common analytical method for large molecules is intact mass by LC/MS. This can be used for the characterization and identification of a product or process-related impurities, or simply as a confirmation of molecular weight. The newly introduced Agilent OpenLab CDS 2.8 SW version comes with a set of features to enable the automatization of biopharma workflows. If you want to know how LC/MSD Spectral Deconvolution of your biopharma samples can be automated, we will provide answers during our presentation. Even more details on Oligonucleotide sequence confirmation and impurities characterization can be acquired using the power of a high-resolution accurate mass system (HRAM) on the Agilent 6545XT AdvanceBio LC/Q-TOF. Analyzing the sample data with the software workflows in Agilent BioConfirm version 12 will support the user to get the trusted answers to their most relevant questions.
<h5>Talk 4 Maximize Your Resources and Simplify Scale-up with AdvanceBio Oligonucleotide Columns</h5>
<ul>
<li>Presented by Dr. Andrea Tripodi, Application Development Engineer, Agilent Technologies</li>
</ul>
Several classes of nucleic acids, such as antisense oligonucleotides, small interfering RNAs (siRNAs), and aptamers are being investigated for potential therapeutic applications. Synthetic oligonucleotides inevitably contain many impurities due to limitations in the efficiency of each chemical reaction used during manufacture. They include deletion sequences (missing one or more nucleotides) and reaction by-products often arising during the final deprotection or cleavage steps. Ion pair reversed-phase (IP-RP) chromatography stands out as the prevalent method for analyzing and purifying oligonucleotides. For increased resolution and separation of your full-length synthetic oligonucleotide from closely related impurities, AdvanceBio Oligonucleotide is the ideal choice. The latest developments include semi-preparative, and lab-scale preparative columns packed with superficially porous particles that provide excellent performance and resolution without compromising column loading. A fast and easy scale-up method from analytical to semi-preparative scale was successfully achieved using a 10 mm ID column enabling higher sample loading using the same analytical LC instrument.
