Post-translational modifications (PTMs) are where so much of biology’s complexity lives, but they are also some of the hardest molecular features to analyze with confidence. Phosphorylation, asymmetric dimethylarginine (ADMA), and O-GlcNAcylation (O-GlcNAc) often occur at low abundance, can be highly labile, and frequently require precise site localization to understand their biological meaning.

For phosphorylation analysis, the platform identified 5,892 unique phosphosites from IMAC-enriched samples and 2,941 unique phosphotyrosine sites after phosphotyrosine enrichment, highlighting strong performance for both broad and highly targeted signaling studies. Just as importantly, the data show that HCD and EThcD provide complementary value, with each fragmentation method contributing unique site identifications and helping resolve ambiguous assignments.The note also highlights the value of EThcD for more analytically demanding PTMs. In ADMA-enriched samples, EThcD delivered more ADMA peptide-spectrum matches and more unique modified peptides than HCD, supporting improved confidence in site characterization. For O-glycopeptides, the Orbitrap Excedion Pro MS uses an intelligent HCD-product-dependent-EThcD strategy that triggers EThcD only when oxonium ions are detected, improving productivity while preserving the fragmentation detail needed for confident glycosite localization.Overall, this technical note shows how Orbitrap Excedion Pro MS enables researchers to go deeper into PTM biology with greater sensitivity, better site confidence, and smarter acquisition. For scientists studying signaling, regulation, and disease mechanisms, it presents a powerful approach for expanding PTM coverage without compromising analytical rigor.<blockquote><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/tn_004377_ov_phosphorylation_ptm_etd_excedion_pro_tn004377_na_en_71f681655f.pdf">Download the technical note</a></h5></blockquote>Visit us on&nbsp;<a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/showcase/72003132/admin/dashboard/">LinkedIn:</a>&nbsp;#PTM #OrbitrapExcedionPro #glycosylation #phosphorylation

The countdown is almost over. In just one week, the international chromatography community will meet in Prague for the <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/events/644">35th International Symposium on Chromatography (ISC 2026)</a>, taking place from September 6–10, 2026. Whether your registration has been confirmed for months or you are still deciding whether to join, now is the time to finalize your plans. Here is what you need to know before ISC 2026 begins.<a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/companies/314">ISC</a> is the oldest conference series dedicated to separation science, with symposia organized since 1956. This September, the Prague Congress Centre will welcome researchers, industry experts, instrument manufacturers, young scientists, and other specialists for five days of chromatography and separation science, covering everything from fundamental research to pharmaceutical, environmental, food, health, and omics applications.But before the scientific sessions begin, there are a few practical details worth checking.<h4>ISC officially starts on September 6 – but activities begin a day earlier</h4>The official dates for ISC 2026 are Sunday, September 6 through Thursday, September 10, but for some participants the conference starts already on Saturday, September 5.The first Short Courses are scheduled for Saturday (<a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/6770">SC 1 – Modern HPLC Separation in Theory and Practice</a> and <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7312">SC 2 – mzmine for LC-MS data analysis</a>), with additional courses continuing on Sunday morning and afternoon. If you have registered for a Short Course, make sure to check its exact date and starting time before arranging your journey to Prague.Sunday then marks the official opening of ISC 2026, with the Opening Ceremony, Award Ceremony, <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7361">plenary lectures</a>, and Welcome Reception introducing delegates to the week ahead.<h4>Haven’t registered yet? You can still join ISC 2026</h4>Missed the late-registration deadline? It is still possible to attend.Onsite registration has been available since August 26, 2026, giving last-minute participants another opportunity to join the symposium. Current onsite registration fees are:<ul><li>Industry: €1,150</li><li>Academic: €890</li><li>Student: €390</li><li>Short Courses: €270</li></ul>The Short Course fee covers participation in up to three Short Courses.One practical point for last-minute registration: bank-transfer payments closed on August 19, so only card payments are now accepted.Full registration includes access to oral and poster sessions, the exhibition, the Sunday Welcome Reception, scheduled lunches and coffee breaks, the electronic Book of Abstracts, and a Prague public transportation pass.<h4>Where is ISC 2026 and how do you get there?</h4>ISC 2026 will take place at the:Prague Congress Centre<ul><li>5. května 65</li><li>140 21 Prague 4</li><li>Czech Republic</li></ul>The venue is particularly easy to reach by public transport. It is located directly on Prague’s Metro Line C at Vyšehrad station, just around five minutes by metro from Muzeum station in the city centre.The Prague Congress Centre brings the lecture halls, exhibition spaces, meeting rooms, and other conference facilities together in one venue, making it easy to move between scientific sessions, posters, industry activities, and the exhibition throughout the day.And since full conference registration includes public transportation in Prague, getting around the city during ISC should be straightforward.<h4>When can you pick up your conference materials?</h4>The registration desk will already be open during the Short Courses and will remain available throughout the symposium.Registration opening hours:<ul><li>Saturday, September 5: 8:30–17:00</li><li>Sunday, September 6: 7:30–19:00</li><li>Monday, September 7: 7:30–18:00</li><li>Tuesday, September 8: 7:30–19:00</li><li>Wednesday, September 9: 8:00–18:00</li><li>Thursday, September 10: 8:30–14:30</li></ul>If you are arriving in Prague on Sunday, allowing some extra time for registration before the Opening Ceremony will make the start of the conference considerably more relaxed.<h4>Now is the time to build your personal ISC program</h4>With several parallel sessions running throughout the week, trying to decide where to go only after arriving at the venue may mean missing something important.The <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7477">main scientific program</a> is organized around three broad areas:<ul><li>Fundamentals</li><li>Bioanalysis and omics applications</li><li>Hyphenated techniques</li></ul>These are complemented by <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7280">Tutorials </a>+ Young Speakers, plenary and invited lectures, poster sessions, the international exhibition, vendor seminars, and industry-focused activities.Before leaving for Prague, take another look at the Interactive Program and mark the lectures, posters, and other activities that are most relevant to you. If you are presenting your own work, this is also the right time to double-check your assigned session, room, and presentation time.And don’t focus only on the oral program. Poster sessions and exhibition breaks are among the best opportunities to discuss new research directly with authors, meet instrument and technology specialists, and make new contacts.<h4>Don’t overlook the vendor seminars and industry program</h4>ISC 2026 is not limited to academic presentations. The conference also includes an extensive industry component, with activities covering current challenges in separation science and practical applications of new analytical technologies.During the lunchtime sessions, participants can attend <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7736">vendor seminars</a> presented by companies including Avantor, Shimadzu, Advanced Materials Technology, Restek, and Thermo Fisher Scientific. Topics range from stationary-phase selectivity and chromatographic modelling to HPLC and LC-MS column technologies and advanced characterization of biotherapeutics.The conference also includes dedicated <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7777">Industry Activities</a> from Monday through Wednesday, bringing together academic and industrial perspectives on topics relevant to analytical laboratories and the future of separation science. One of the discussions, for example, will examine how education in separation science can better reflect the skills required by modern industry, while another will focus on sustainability and the practical implementation of greener analytical workflows.On Wednesday, participants can also join the <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/7801">Publishing Workshop</a>, another activity worth adding to the schedule if scientific publishing is part of your work.<h4>Test your chromatography knowledge at the ISC Quiz</h4>Not every session needs to be completely serious.On Tuesday, September 8 from 18:30 to 19:30, ISC will host an interactive Chromatography Quiz, combining practical questions, chromatography fundamentals, unusual facts, and lighter challenges.There is no advance registration required. Any registered conference participant can join, but remember to bring a smartphone—the quiz uses live participation through a QR code.Results will be scored in real time, and prizes will be awarded to the top three participants.<h4>Start networking from the first evening</h4>The scientific program may be the main reason to attend ISC, but the conversations between sessions can be equally valuable.The first major networking opportunity comes immediately on Sunday.The Welcome Reception will take place on September 6 from 18:30 to 20:00 in the second-floor foyer of the Prague Congress Centre. It is open to registered participants and accompanying persons and includes a light buffet and drinks.As it takes place immediately after the opening program, it is an ideal opportunity to reconnect with colleagues, meet new contacts, and start conversations before the full parallel scientific program begins on Monday.Another social highlight will be the Gala Dinner on Wednesday, September 9 from 19:00 to midnight at the National House Vinohrady.The Gala Dinner requires a separate €100 ticket, is not included in the standard registration fee, and has a smart-casual dress code. Participants should also note that transportation to and from the venue is not organized by the conference.<h4>And perhaps leave a little time for Prague</h4>A conference schedule can fill up quickly, but ISC 2026 is taking place in one of Europe’s most walkable cities.If you find some free time between sessions, Vyšehrad is only about a 10-minute walk from the Prague Congress Centre and offers panoramic views across Prague and the Vltava River. It is an easy option for a short walk without travelling back into the historic city centre.See you at ISC 2026 in Prague!

ACQUITY Advanced Polymer Chromatography (APC) Columns are designed for polymer scientists like you, with novel capabilities for chromatographic efficiency, speed and resolution that cannot be matched by conventional GPC methods. With these columns, you can quantify and characterize polymer samples with confidence and accuracy while maximizing productivity.The Ethylene Bridged Hybrid (BEH) particles used in ACQUITY APC Columns enable rapid solvent switching and the ability to use multiple conditions for the same bank of columns. Conventional polymeric stationary phases are dedicated to a single set of analytical conditions and solvent because the chromatographic bed is vulnerable to shrinking and swelling. By eliminating this undesirable behavior, ACQUITY APC Columns allow for maximum robustness and method development flexibility.<h4>Overview</h4><ul><li>Eliminate the shrinking and swelling that often occurs with polymeric stationary phases upon solvent switching with a stable chromatographic column bed&nbsp;</li><li>Achieve unmatched separation speed, resolution, and chromatographic efficiency from optimized pore volumes and particle size</li><li>Meet workflow requirements with 1.7 and 2.5 μm columns for organic and aqueous size-based separation</li><li>Achieve industry-leading column-to-column reproducibility with exceptionally reliable columns from a tightly controlled column manufacturing process</li><li>Recommended Use: For rapid and accurate chromatographic characterization of synthetic polymer and macromolecular species.&nbsp;</li></ul><h4>ACQUITY APC Column Featured Technologies</h4><h5>BEH Technology</h5><ul><li>Rugged hybrid organic/inorganic base particle</li><li>Improved peak shape for bases- low silanol activity</li><li>Wider operating pH range for method development flexibility</li><li>Mechanical strength for maximum column efficiency at UHPLC operating pressures</li></ul><h4>ACQUITY APC Column Characteristics</h4><h5>ACQUITY APC XT Columns</h5><ul><li>Designed to provide high efficiency sized-based separations for organic soluble polymer characterization</li><li>Uses BEH particle technology</li><li>Stable column bed that resists shrinking and swelling for easy mobile-phase solvent switching</li><li>Features an extended temperature range up to 90 °C</li><li>Designed for organic solvent-based separations</li></ul><h5>ACQUITY APC AQ Columns</h5><ul><li>Designed to provide high efficiency sized-based separations for water soluble polymer characterization</li><li>Uses BEH particle technology</li><li>Robust separations up to 45 °C</li><li>Designed for aqueous-soluble polymer separations</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_ACQUITY_APC_Columns_2268ceb5f5.jpeg" alt="Waters: ACQUITY APC Columns" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_ACQUITY_APC_Columns_2268ceb5f5.jpeg 234w," sizes="100vw" width="1024" height="682"><h4>Unprecedented capacity for rapid solvent switching</h4>Use multiple conditions for the same column bank with rapid solvent switching using the rigid hybrid particles in ACQUITY APC Chromatography Columns. Conventional polymeric phases are often dedicated to single analysis conditions because the chromatographic bed is vulnerable to shrinking and swelling that can be potentially harmful to the column. By eliminating this constraint, ACQUITY APC Chromatography Columns provide more freedom for method development and deliver advanced polymer characterization for a diverse range of samples.<h4>Reduce calibration time by a factor of 3-5x and increase resolution</h4>With long conventional Gel Permeation Chromatography (GPC) run times of up to one hour or more, analyses of standards and samples can be quite time-consuming. In addition to long GPC run times, the large extra-column volume of conventional GPC systems can result in peak bandspreading, reducing the resolution and thus accuracy of the calibration points. Combined with the lower dispersion ACQUITY APC System, small particle ACQUITY APC Columns deliver less bandspreading and narrower, sharper peaks compared to the conventional GPC system. Additionally, robust sub-3-µm APC Column Technology supports higher flow rate and backpressures, thereby improving resolution.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_A_comparison_of_run_times_and_resolution_for_polystyrene_standards_Mp_100_K_10_K_and_1_K_on_a_conventional_GPC_system_and_the_ACQUITY_APC_System_37cfb15ed5.jpeg" alt="Waters: A comparison of run times and resolution for polystyrene standards (Mp: 100K, 10K, and 1K) on a conventional GPC system and the ACQUITY APC System.

Each step of our column manufacturing process is monitored and tightly controlled to maintain unmatched product reproducibility. Every test, from raw material characterization to final batch analysis, is designed to ensure that ACQUITY APC Columns perform the same from column-to-column, batch-to-batch, and year-to-year.
