EAD vs. ETD: Choosing the right fragmentation technique for small molecule Met ID studies by Kirsten Craven | Blogs, PharmaIn drug discovery and development, Metabolite Identification (Met ID) plays a critical role in understanding biotransformation pathways, ensuring safety, and meeting regulatory requirements. Advanced mass spectrometry techniques have revolutionized this process, particularly through electron-based fragmentation methods such as Electron Activated Dissociation (EAD) and Electron Transfer Dissociation (ETD). While both techniques leverage electron interactions to generate informative fragment ions, they differ significantly in mechanism, performance, and suitability for Met ID workflows.

Harnessing the Power of MRM3 for Large Molecule Quantitative Bioanalysis by SCIEX Community | Biopharma, BlogsIn a previous blog outlining the advantages of high-resolution accurate mass measurements for protein quantitation using the TripleTOF 6600, it was noted that although the triple-stage quadrupole demonstrated high sensitivity when operated in multiple reaction monitoring mode (MRM), the relatively low-resolution measurement of m/z failed to discriminate Rituximab response from nominally isobaric interferences given the complexity of the proteolytically digested samples (June 28/2016). While the accurate mass filtering capabilities of the TripleTOF 6600 represents one mechanism for achieving increased selectivity over MRM, the triple quadrupole/linear ion trap (LIT) hybrid platform represented by the QTRAP® 4500, 5500, 6500 and 6500+ systems provides an alternative technique by leveraging a third stage of MS, often referred to as MRM3. In this blog, we outline the MRM3 scan function and survey several large molecule applications which utilize the additional stage of fragmentation in the LIT to yield significant improvements in achievable detection limits when compared to MRM.

Quantitation of Antibiotics and Insecticides in Poultry Feed using LC-MS/MS by SCIEX Community | Blogs, Food / BeverageQuantitating antibiotics and insecticides in poultry is serious business. Overuse can lead to antibiotic resistance while insecticide residuals can cause harmful side effects in humans. In the United States, for example, the Federal Drug Administration (FDA), has offered up a plan to limit common antibiotics in feed, which are used to encourage growth. However, this is a voluntary plan, and as the following application note, “Quantitation of Antibiotics and Insecticides in Poultry Feed using LC-MS/MS,” points out, antibiotics have been shown to accumulate in poultry feathers, which are in turn used for nutritional elements in the feed.
Screening Novel Psychoactive Substances with Confidence by SCIEX Community | Blogs, ForensicHow do you know what you can’t see? This is the challenge many a lab faces as they relentlessly test for novel psychoactive substances (NPS) as unknown samples with an ever-changing ingredient list make discovery difficult work at best. There are many reasons for the complexities of which you can discover in this application note, “Accurate Mass Screening Workflows for the Analysis of Novel Psychoactive Substances.” However, the biggest of which is that non-targeted findings can turn up thousands of molecular features in a single sample. Sifting through the peaks is laborious, and many are normal besides.
Why Study Lipids? by Baljit Ubhi | Blogs, Life Science Research, LipidomicsI had an opportunity to follow up with Steven M Watkins, Ph.D. to talk about the importance of studying lipids in disease. Steve has been working in the lipids field for over 20 years and is one of the foremost experts in lipid biology. Steve founded Lipomics in 2000, an early metabolomics company focused on quantitative lipidomics and had followed that company through a series of changes that led to its involvement in the clinical diagnostic development and global metabolomics. Steve authored over 70 peer-reviewed publications including several book chapters on lipids and lipid metabolism. His presentations on this topic are fascinating and very informative, so I wanted to capture some of his thinking here!

The last rule, UCMR3, was published May 2, 2012, and is the focus of the following application note, “Analysis of Perfluoroalkyl (PFFA) Acids Specified under the UCMR3 Using the QTRAP® 6500 LC-MS/MS system,” which can be found in the Food and Environmental Compendium.
SCIEX helps set food standards in China by Brandon McInnis | Blogs, Food / BeverageOne of the biggest concerns of Chinese citizens is food safety1. Even though China ranks second in global economies2, crowding, industrial pollution, labor and certain agriculture practices have contributed to this.

Discover the new and accurate SCIEX way to enhance your routine food allergen testing by SCIEX Community | Blogs, Food / BeverageFood allergy is an immune-mediated, adverse reaction to an antigenic protein. Even limited exposure to an antigen can provoke a significant reaction in sensitive individuals, causing rashes, itching and swelling in the mouth, nausea, vomiting, and asthma. Additionally, food allergies are the leading cause of anaphylaxis, an acute, potentially deadly allergic reaction. The prevalence and severity of food allergies are rising, with approximately 150 million people suffering from food allergies worldwide.1, 2 Presently, there is no cure for food allergies, and sufferers must rely on the correct labeling of foods to avoid consuming allergens. Hence, the development of sensitive and accurate analytical methods to screen for the presence of allergens in food products is necessary for the prevention of potentially life-threatening health problems for allergy sufferers.

Protein Quantitation Workflows using the TripleTOF 6600: A Case Study for Rituximab by SCIEX Community | Biopharma, BlogsAlthough the triple-stage quadrupole (QQQ) mass spectrometer remains the pillar for quantitative LC-MS/MS bioanalytical assays, due in part to the platforms’ high duty cycle when operated in multiple-reaction monitoring (MRM) mode, the applicability of high-resolution mass spectrometry (HRMS) has become of increasing importance for protein quantitation given the complexity of proteolytically digested samples in the surrogate peptide approach. While the QQQ demonstrates high sensitivity and specificity, the relatively low-resolution measurement of m/z may fail to differentiate analyte response from nominally isobaric background interference. In contrast, HRMS with accurate mass assignment of product ion allows interference to be resolved through judicious selection of a post-acquisition mass extraction window whose tolerance is largely dictated by the effective resolution and stability of mass calibration.
