Use a Bigger SWATH Library and Get More Protein Coverage From Your Sample

If you have a TripleTOF® System and you’re using SWATH Acquisition for your quantitative proteomics experiments, you’ve made the right choice. SWATH is a data independent workflow that enables data to be acquired for every detectable analyte in a complex sample. You create a digital map of the sample that can be mined for new information any time new biological insights are hypothesized. It’s all there!

A rising star in food allergen research: proteomics of shellfish allergen

A rising star in food allergen research: proteomics of shellfish allergen

It’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)

Multi-Laboratory Study Highlights the Quantitative Reproducibility of SWATH Acquisition (Nature Communications Paper)

Reproducibility 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

We 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

Happy Birthday to SWATH Acquisition! 5 Years of Innovation

With 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).

5 Tips for Calibrating a QTOF Mass Spectrometer

Do you have questions about your mass spec? How about a workflow? Our community members are involved in active discussions and receive expert answers from customers like you, SCIEX scientists, and support specialists every week. One recent topic concerned the automatic calibration on TripleTOF® systems as answered by Dr. Christie Hunter whose focus is developing and testing innovative MS workflows for omics research through working collaboratively with the instrument, chemistry, and software research groups.

The Aebersold group at ETH Zurich focuses on proteomics research, including the development of techniques to study the proteome as an integrated entity. In collaboration with SCIEX, the group established SWATH® Acquisition mass spectrometry, a data-independent acquisition (DIA) method capable of fragmenting multiple peptide species concurrently. The resulting comprehensive data set can be retrospectively re-mined, enabling maximum benefit to be derived from any study.
