<p><strong>At MSACL 2025, a Thermo Fisher Scientific–sponsored workshop led by Qin Fu addressed one of the most persistent challenges in proteomics: how to efficiently and reproducibly translate biomarker discoveries into clinically meaningful assays. Drawing on experience spanning academia and industry—including prior work in Jennifer Van Eyk’s lab—Fu shared practical insights into building a scalable, end-to-end biomarker discovery-to-validation pipeline.</strong></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Accelerating_Biomarker_Discovery_and_Validation_From_Discovery_to_Clinical_Utility_9558364cf2.jpg" alt="Thermo Fisher Scientific: Accelerating Biomarker Discovery and Validation: From Discovery to Clinical Utility" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Accelerating_Biomarker_Discovery_and_Validation_From_Discovery_to_Clinical_Utility_9558364cf2.jpg 245w," sizes="100vw" width="1024" height="512"></p><p>The session highlighted how emerging mass spectrometry technologies, automation, and informatics are reshaping biomarker research—reducing complexity, improving reproducibility, and accelerating the path to clinical utility.</p><h3><strong>The three tiers of biomarker assays</strong></h3><p>The workshop opened with a review of the widely accepted three-tier framework that guides biomarker development from early discovery through clinical validation:</p><h4><strong>Tier 3 – discovery</strong></h4><p>Exploratory, untargeted workflows such as data-dependent acquisition (DDA) and data-independent acquisition (DIA). These approaches prioritize breadth, enabling the identification of large-magnitude biological changes across hundreds to thousands of analytes, typically with low-to-moderate precision and without internal standards.</p><h4><strong>Tier 2 – verification</strong></h4><p>Research-grade targeted assays, including parallel reaction monitoring (PRM) and multiple reaction monitoring (MRM). These methods focus on tens to hundreds of analytes, delivering improved precision and repeatability to confirm trends observed during discovery.</p><h4><strong>Tier 1 – validation</strong></h4><p>Clinically validated assays designed to meet rigorous quality and regulatory standards. These workflows incorporate internal standards and strict quality controls to ensure quantitative reproducibility suitable for clinical and translational use.</p><p>Each tier represents a critical step toward ensuring that biomarker candidates can ultimately deliver reliable patient benefit.</p><h3><strong>The central challenge: from sample to signal</strong></h3><p>Reliable biomarker development depends on consistency across the entire analytical workflow—from biological sample preparation to mass spectrometry data acquisition and downstream analysis. Every step introduces potential sources of variability, and minimizing this analytical noise while preserving biological signal is essential.</p><p>Automation emerged as a central theme of the workshop. Beyond improving throughput, automation fundamentally enhances reproducibility. Robotic sample preparation reduces variability associated with digestion, pipetting, and handling—enabling consistent performance across hundreds or thousands of samples, a scale that is difficult to achieve manually.</p><h3><strong>Technological innovation powering a paradigm shift</strong></h3><p>Recent advances in mass spectrometry are enabling researchers to bridge the gap between discovery and validation more efficiently than ever before. The workshop highlighted several Thermo Fisher Scientific platforms driving this shift:</p><ul><li><strong>Thermo Scientific Orbitrap Astral mass spectrometer</strong><br>Optimized for discovery workflows, the Astral system delivers rapid acquisition and deep proteome coverage while maintaining high precision across large cohorts.</li><li><strong>Thermo Scientific Stellar platform</strong><br>Designed for high-throughput targeted quantification, the Stellar platform supports scalable PRM workflows. Features such as PRM Conductor enable adaptive retention time tracking, which is essential for robust performance in large studies.</li><li><strong>Thermo Scientific OptaSpray Ion Source (under evaluation)</strong><br>A hands-free ionization source designed to deliver consistent spray performance with simplified maintenance, supporting reproducibility across thousands of injections.</li></ul><p>Together, these technologies create a smoother continuum across assay tiers, shortening timelines and reducing barriers to clinical translation.</p><h3><strong>Case study: Inflammatory bowel disease (IBD) cohort</strong></h3><p>A key highlight of the presentation was a large-scale biomarker study in inflammatory bowel disease (IBD). The team conducted a 500-sample discovery analysis, followed by validation in a 1,000-sample cohort. Discovery was performed using the Orbitrap Astral system, while targeted validation employed the Stellar platform.</p><p>This integrated approach successfully confirmed established biomarkers such as C-reactive protein (CRP) while also identifying novel protein candidates with strong translational potential. Importantly, these markers demonstrated consistency across discovery and validation data sets—underscoring the power of advanced instrumentation combined with robust workflows and informatics.</p><h3><strong>From high quantity to high quality</strong></h3><p>Historically, biomarker discovery has involved a tradeoff between throughput and data quality. The workshop demonstrated that this compromise is no longer necessary. By integrating automated sample preparation, optimized informatics, and next-generation mass spectrometry, researchers can now generate high-quality, high-throughput data that is both scalable and reproducible.</p><p>This shift enables faster discovery while increasing confidence that candidate biomarkers are ready for downstream validation and clinical follow-up.</p><h3><strong>The future of biomarker translation</strong></h3><p>The workshop concluded on an optimistic note. Innovations in proteomics are fundamentally transforming biomarker development—shortening timelines, reducing costs, and accelerating the transition from discovery to clinical application.</p><p>By integrating platforms such as Orbitrap Astral, Stellar, and OptaSpray, Thermo Fisher Scientific is helping advance a new era of translational biomarker science—where precision, scalability, and reliability work together to deliver meaningful clinical impact.</p><p><i>Watch the full workshop recording to </i><a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=ziyffQzZTwk"><i>explore the data, workflows, and results behind this end-to-end approach to biomarker discovery and validation.</i></a></p><h3><strong>Intended use disclaimer</strong></h3><p>General Laboratory Equipment – Not For Diagnostic Procedures.<br>Thermo Scientific general laboratory equipment, consumables, and software are intended for research, academic, and industrial use only.

Accelerating Biomarker Discovery and Validation: From Discovery to Clinical Utility

<p><strong>Interlaboratory comparisons (ILCs) have been used for more than a century and many important concepts are linked to them. This leaflet addresses the basic terminology of ILCs, why some colloquial terms can be misleading or misunderstood, and the importance of harmonisation.&nbsp;</strong></p><p>An ‘ILC’ is the <i>organisation, performance and evaluation of measurements or tests on the same or similar items by two or more laboratories in accordance with predetermined conditions</i> [1]. ILCs have a variety of overall – and detailed – objectives, the three most common [2] being:</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_3_9993b9fb0f.jpg" alt="Eurachem: Let’s call a PT scheme a PT scheme" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_3_9993b9fb0f.jpg 245w," sizes="100vw" width="1516" height="472"></p><h4><strong>Some comparisons have special names&nbsp;</strong></h4><p>The evaluation of participant (laboratory, organisation or individual) performance is typically referred to as ‘<strong>proficiency testing</strong>’ (PT) or ‘<strong>external quality assessment</strong>’ [1]. When the main objective is evaluating the performance of, for example, a candidate standard method, the ILC is often called a ‘<strong>method performance study</strong>’ or a ‘<strong>collaborative study</strong>’ [2, 3]. The former is quite clear whereas wording such as “<strong>collaborative</strong>” and “<strong>cooperative</strong>” just stresses joint effort. A project aimed at producing a new certified reference material may involve several laboratories conducting analyses on agreed properties [4]. Not surprisingly, this work is sometimes labelled as a ‘<strong>material certification study</strong>’. Special ILCs used to demonstrate measurement capabilities of National Metrology Institutes are called ‘<strong>key comparisons</strong>’, ‘<strong>supplementary comparisons</strong>’, and ‘<strong>pilot studies</strong>’ [5].&nbsp;</p><h4><strong>Some terms can be confusing&nbsp;</strong></h4><p>Other terms for ILCs, including ‘ring test’, ‘round robin’ and ‘circle analysis’, are common in the literature. They have, however, been used for different objectives and different designs and may be ambiguous or understood differently by laboratory staff. The use of these terms may, for example, imply a specific way of distributing the ILC sample. ISO/IEC 17043 uses ‘sequential scheme’, for a PT where a unique item is transferred between the participants and ‘simultaneous scheme’, in which similar items from a batch are distributed simultaneously to the participants [1].&nbsp;</p><p>Terms like ‘<strong>measurement audit</strong>’, ‘<strong>interlaboratory testing scheme</strong>’, ‘<strong>measurement comparison scheme</strong>’, ‘<strong>rapid performance evaluation scheme</strong>’ and ‘<strong>intercalibration</strong>’ may not correctly reflect the category of laboratory involved, or the type of work participants do during the ILC.&nbsp;</p><p>When in 1994 the IUPAC defined and described three major types of ‘interlaboratory studies’, the word ‘study’ was preferred to synonyms such as ‘trial’, ‘exercise’, ‘test’, ‘evaluation’ or ‘check’ [2].</p><h4><strong>Let’s try to harmonise&nbsp;</strong></h4><p>Many laboratory staff are unaware of official terms related to ILCs but recognise the acronym PT and words like ‘ring test’. Ideally, we would use a common scientific language, but harmonisation is time consuming. Terms appear and disappear and definitions change. The same term can be defined differently, even in different international standards. Lack of standards and guidelines in local languages can cause confusion and contribute to spreading of less appropriate terms.&nbsp;</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_2_820043ce8b.jpg" alt="Eurachem: Let’s call a PT scheme a PT scheme" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_2_820043ce8b.jpg 234w," sizes="100vw" width="1006" height="671"></p><p>Much confusion can be avoided by clear reference to relevant standards and sectoral guides. ISO/ IEC 17043 [1] and ISO 13528 [6] contain many important concepts related to PT schemes and other ILCs. Some of these are also incorporated into ISO/IEC 17025 [7]. Additional useful, and free, tools are the Eurachem PT Guide [8] and the ISO online browsing platform [9].&nbsp;</p><p>In writing guidance and instructions, remember that the term ‘interlaboratory comparison’ has a broad meaning and can be used for all cases described above. Sometimes this is clear enough for the reader. In other cases, use acknowledged terms that reflect the detailed objective of the ILC. Let’s call a PT scheme a PT scheme!</p>

This presentation addresses hidden adulteration associated with sugar-fed bee colonies, highlighting implications for authenticity, production practices, and the need for a more precise characterization of honey to ensure consumer trust.</p><h5><strong>Analytical and toxicological methods for safety of food contact materials</strong></h5><ul><li>Erich Leitner from Graz University of Technology, Institute of Analytical Chemistry and Food Chemistry, Graz, Austria</li></ul><p>Food packaging plays a critical role in protecting and preserving food throughout the supply chain. All packaging materials intended to come into contact with food must comply with strict EU safety rules. Due to increased complexity of packaging solutions, lowering legal limits and increasing numbers of target compounds, we also have to adapt the strategies used to verify and guarantee the safety of these materials.</p><h5><strong>Data-driven strategies to reduce complexity in non-target HRMS analysis of food samples</strong></h5><ul><li>Anneli Kruve from Stockholm University, Stockholm, Sweden</li></ul><p>LC/HRMS based non-target screening can detect hundreds to thousands of chemical features in complex food and environmental samples. Investigating all of these in detail is practically impossible, so which ones to focus on? Novel computational tools developed in computational mass spectrometry allow predicting the toxicity and concentration of the detected chemical features even if these have not yet been fully structurally elucidated. Combining these predictions enables us to focus on the chemical features possessing high risk.</p><h5><strong>Role of AI in the identification of emerging food systems risks</strong></h5><ul><li>Ákos Bernard Jóźwiak from Syreon Research Institute, Budapest, Hungary</li></ul><p>AI-assisted evidence synthesis – spanning curated scientific evidence, exposome data, and network analysis – is the backbone of next-generation emerging chemical food safety risk identification, enabling earlier signals and more resilient surveillance systems.</p><h5><strong>Challenges of microplastics analysis in the context of food safety</strong></h5><ul><li>Dorte Herzke from Norwegian Institute of Public Health, Oslo, Norway</li></ul><p>Food and food packaging are major sources of micro- and nanoplastic exposure. Plastics used in processing, storage, and packaging can release particles through heat, abrasion, and degradation.
