High complexity of the lipidome

The complexity of the lipidome is diverse in the structure and there are many combinatorial isoforms that are available within nature.  Currently, many different techniques are required to fully characterize a lipid molecule. What if you could do it in a single...

Overcoming uncertainty in your PFAS analysis

Overcoming uncertainty in your PFAS analysis

Just 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.

Nitrosamines: Where are we now?

Nitrosamines: Where are we now?

Nitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.

Detecting low levels of drugs and their metabolites in hair and nail samples using LC-MS/MS

Detecting low levels of drugs and their metabolites in hair and nail samples using LC-MS/MS

You 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.

Guide decisions during cell line development with more information at the intact level

Guide decisions during cell line development with more information at the intact level

Monitoring 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

Maximize NPS analysis with accurate mass spectrometry

LC-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

Unlock the benefits of nominal mass spectrometry for NPS analysis

The 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.

The Promise of Precision Medicine

Here is the latest update on the Worldwide Efforts to Accelerate Precision Medicine

The NIH recently issued a press release in early July announcing $55 million in awards. According to the release, the $55 million award in the fiscal year 2016 will go towards building the foundational partnerships and infrastructure needed to launch the Cohort Program of President Obama’s Precision Medicine Initiative (PMI). The PMI Cohort Program is a landmark longitudinal research effort that aims to engage 1 million or more U.S. participants to improve the ability to prevent and treat disease based on individual differences in lifestyle, environment, and genetics.

Why Study Lipids?

Why Study Lipids?

I 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!

Improved complex sample processing for higher quality of results, reproducibility and depth of proteomic analysis

SCIEX partners to improve depth of proteome coverage
SCIEX and Pressure BioSciences address a major challenge for researchers performing complex sample preparation by marketing a complete solution to increase the depth, breadth, and reproducibility of protein extraction, digestion, and quantitation in all tissue types, especially challenging samples like tumors.

Industrialize Your Quantitative Proteomics Using a More Simplified Sample Prep

Industrialize Your Quantitative Proteomics Using a More Simplified Sample Prep

in part 1 and part 2 of this blog series we discussed how you can increase your efficiency for high throughput quantitative proteomics by industrializing your sample analysis and data processing. Microflow SWATH® Acquisition on your TripleTOF® system coupled with OneOmics™ data analysis tools allow you to run samples faster, collect data faster, and process your data files faster. It all adds up to getting more meaningful biological information in a shorter amount of time.

Industrialize Your Quantitative Proteomics Using a More Simplified Sample Prep

Industrialize Your Quantitative Proteomics with the OneOmics Project

For many labs, the days are long gone when it was acceptable to run only a few samples a week for your quantitative proteomics projects. The pressure for faster turn-around times, to support larger cohort studies, to sustain multiple research directions, and to transition from a purely unbiased discovery mode to verifying something truly unique and interesting, all demand a faster pace. Many labs are now being asked to analyze a hundred samples a week or more. In part 1 of this blog series, we saw how moving to a microflow SWATH workflow can dramatically increase your throughput with little compromise on overall results. In this part, we’ll address what to do with all of this data because it’s just no good if all we’ve done is move the bottleneck downstream.
