The History of Isotopic Labels for Quantitative Proteomics by Subhasish.Purkayastha@sciex.com | 0 CommentsProteomics has become a vital tool for biological scientists performing research on the healthy and diseased states of living things. It involves the large scale and systematic analysis of all proteins within a given cell, tissue, or organism. Because proteins are regulated by many different internal and external stimuli, the proteome is dynamic and quantities of proteins can change from one state to the next. Therefore, in order to be of the highest utility, proteomics experiments need to both identify and quantify proteins so that comparative studies can be done, such as between healthy cells and tumor cells, or the comparison of different treatment regimens.
The Promise of Precision Medicine by SCIEX Community | 0 CommentsHere 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.
Improved complex sample processing for higher quality of results, reproducibility and depth of proteomic analysis by ken.hamill@sciex.com | 0 CommentsSCIEX 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 with the OneOmics Project by Christie Hunter | 0 CommentsFor 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.
Easy switching of sources and LC flow regimes on the ZenoTOF 7600 system by Christie Hunter | Data acquisition, Ion sources, Life Science Research, Proteomics, SCIEX information, ZenoTOF 7600 systemThis series of videos outlines how a user can easily switch sources and operate the system in different LC flow regimes.
A rising star in food allergen research: proteomics of shellfish allergen by SCIEX Community | Blogs, Food / Beverage, Life Science Research, ProteomicsIt’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

Multi-Laboratory Study Highlights the Quantitative Reproducibility of SWATH Acquisition (Nature Communications Paper) by Christie Hunter | Blogs, Life Science Research, ProteomicsReproducibility is one of the key tenets of the scientific method. But in a recent survey published in Nature, more than 70% of researchers were not able to reproduce another scientist’s experiments, and more than half could not reproduce their own experiments1. While the reasons for this are many, at least some of them stem from issues inherent in data collection.
SCIEX Lands HUPO Science and Technology Award by Tom Knapman | Blogs, Life Science Research, ProteomicsWe are pleased to congratulate its research scientists Stephen Tate and Ron Bonner (retired) for being awarded this year’s Science and Technology award at HUPO 2017 in Dublin Ireland. The Science and Technology Award at HUPO recognizes an individual or team who were key in the commercialization of a technology, product, or procedure that advances proteomics research
Happy Birthday to SWATH Acquisition! 5 Years of Innovation by Christie Hunter | Blogs, Life Science Research, ProteomicsWith its introduction at the HUPO World Congress in 2010 in Sydney Australia by Ruedi Aebersold, SWATH® Acquisition instantly intrigued scientists around the world. Here was a new technique with the potential to revolutionize the way proteomics studies were performed! Based on a data independent acquisition strategy using a SCIEX TripleTOF® 5600 system, SWATH was able to consistently identify and quantify at least as many peptides and proteins as other far more mature proteomics strategies on the market, but with quantitative accuracy and reproducibility rivaling gold standard MRM experiments! This solution was made broadly available to researchers with a full launch of SWATH Acquisition in the Analyst® TF 1.6 Software on the TripleTOF 5600+ System at ASMS 2012 in Vancouver (A Mine of Quantitative Proteomic Information. Prof Dr. Ruedi Aebersold, Head of the Department of Biology, ETH Zurich).
