A rising star in food allergen research: proteomics of shellfish allergen by SCIEX Community | 0 CommentsIt’s important to know what you’re eating, especially if you suffer from a food allergy. About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion

Detect the Signal, Not the Noise by SCIEX Community | 0 Comments Improving the specificity and selectivity of your assay Your LC-MS assay is only as good as its power to discern your target compound from everything else. Standards dissolved in clean solvents can make beautiful assays, but analytes in real-world samples can behave...
Pharma perspectives: The influence of LC-MS innovation on drug development outsourcing by Kean Woodmansey | Blogs, Pharma, ZenoTOF 7600 systemIt is no secret that (bio)pharmaceutical research and development is complex, both scientific and regulatory processes. Working for a contract research organization and more recently for SCIEX has provided an interesting perspective on trends the market experiences that affect many of us.
Overcoming uncertainty in your PFAS analysis by Karl Oetjen | Blogs, Environmental / IndustrialJust like gum on the bottom of a shoe, the existence of per- and poly-fluorinated alkyl substances (PFAS) in our environment is a sticky one. If you’re in the field of environmental testing, then you’re all too familiar with the threat these substances have on public health. While we have learned a lot about them over the years, there is still much more to understand. With the right detection methods, we can gather the information we need to empower us to make informed decisions on reducing the risks they impose.
Detecting low levels of drugs and their metabolites in hair and nail samples using LC-MS/MS by SCIEX Community | Blogs, Forensic, ToxicologyYou probably have heard of testing blood and urine samples for the presence of drugs and their metabolites. But do you know about the benefits of hair and nail analysis? In a recent webinar, Tina Binz, Deputy Head of the Center for Forensic Hair Analysis, University of Zurich, discussed the benefits of developing comprehensive and sensitive LC-MS/MS for the detection of low-level drugs and metabolites in keratinized matrices.
An overview: LC-MS analysis of targeted protein degraders and their metabolites by Kirsten Craven | Blogs, Pharma, ZenoTOF 7600 systemTargeted protein degraders (TPD) are a relatively new therapeutic modality that opens the potential to target disease-causing proteins. These disease-causing proteins have been highly challenging for traditional small-molecule therapeutics to treat, making TPDs an exciting new therapeutic modality.
Guide decisions during cell line development with more information at the intact level by Roxana McCloskey | Biopharma, Blogs, Intabio ZT system, ZenoTOF 7600 systemMonitoring product quality attributes (PQAs) throughout monoclonal antibody (mAb) development is vital to ensuring drug safety and efficacy. By adopting orthogonal analytical techniques and integrating new technologies that have the potential to provide more information, it is possible to improve product quality and manufacturing efficiency and make more informed decisions.
Maximize NPS analysis with accurate mass spectrometry by Pierre Negri | Blogs, Forensic, SCIEX OS software, Toxicology, ZenoTOF 7600 systemLC-MS/MS is a powerful analytical tool in forensic toxicology testing that can support a variety of testing regimes such as screening, confirmation and quantitative workflows. More specifically, analysis of NPS using LC-MS/MS provides many advantages, including the ability to reliably detect new drugs and their metabolites from a variety of biological matrices.
Unlock the benefits of nominal mass spectrometry for NPS analysis by Pierre Negri | Blogs, Clinical, Forensic, QTRAP / Triple Quad, ToxicologyThe development of analytical methods for the detection and quantitation of drugs and metabolites in a range of biological matrices is a challenging process. Forensic toxicology labs need a reproducible and reliable methodology to ensure the robustness of the data and the quality of the results. They also need robust and sensitive instrumentation that can detect drugs at trace levels with high specificity, especially when it comes to novel psychoactive substances (NPS), which can be difficult to monitor and control.
What has the Echo® MS system done for the pharma industry? (And don’t just take our word for it!) by Kirsten Craven | Blogs, Discovery, Echo® MS+ system, PharmaSCIEX was very proud to have an illustration of the Acoustic Ejection Mass Spectrometry (AEMS) technology that powers the Echo® MS system on the front cover of the Journal of the American Society for Mass Spectrometry in January 2023. The associated article—Ultrahigh-Throughput Intact Protein Analysis with Acoustic Ejection Mass Spectrometry—was co-authored by scientists from SCIEX and Merck.
Short-chain PFAS compounds are on the rise- Craig’s PFAS Vodcast Cora Young by Craig Butt | Blogs, Environmental / IndustrialRead time: 2 minutes Short-chain per- and polyfluoroalkyl substances (PFAS) are increasing in the Canadian Arctic environment, with the most rapid increases occurring post-2000, according to a recent study in Geophysical Research Letters (April 2020). For example,...
Identifying the unknown PFAS profile in firefighting foams/AFFF by Craig Butt | Blogs, Environmental / IndustrialAccording to a recent study from Harvard University, the US EPA, and NIEHS, traditional targeted analysis techniques poorly characterize the PFAS composition of contemporary PFAS-based firefighting foams, know as aqueous film-forming foams (AFFF). Using the EPA 533 PFAS drinking water method for the analyte list, the researchers found that targeted mass spectrometry methods accounted for <1% of organic fluorine content. This is important because it demonstrates that targeted analysis methods miss nearly all the PFAS compounds in modern AFFF mixtures, thus underestimating the risk to human health and the environment.
