SCIEX Partners with University of Manchester to Develop Biomarker Discovery Centre and Multi-Omics Centre for Precision Medicine

SCIEX, a global leader in life science analytical technologies, has today announced that The University of Manchester, UK, has invested in a large suite of high-end SCIEX mass spectrometers for targeted and next-generation proteomics for its new Stoller Biomarker Discovery Centre. With SCIEX’s SWATH® Acquisition technologies, the Centre will be one of the biggest clinical proteomics facilities in the world. It will focus on industrializing proteomics research, and spearhead a series of biomarker development projects and international collaborations.

AB SCIEX Next-Generation Proteomics Platform Transforms Proteomics Research

AB SCIEX, a global leader in life science analytical technologies, recently introduced the TripleTOF® 6600 system with SWATH™ Acquisition 2.0 – the company’s revolutionary solution for quantitative proteomics. This high-resolution, accurate-mass system, combined with the new SWATH™ Acquisition 2.0, brings new power to proteomic data challenges for advanced biomarker discovery and systems biology. As the emphasis in proteomics research shifts from cataloguing to comprehensive quantitation, the AB SCIEX solution is uniquely positioned, enabling the quantification of thousands of proteins across large sample sets with a level of data completeness and quantitative accuracy and precision that have only been achievable by “gold-standard,” targeted MRM in the past.

National Cancer Institute Awards Labcyte $1 Million for Novel High-Throughput Cancer Biomarker Detection

Labcyte Inc., the acoustic dispensing company, has been awarded $1 million to create an innovative process to detect cancer-related proteins in samples, with initial work in breast cancer detection. The unsurpassed precision and accuracy of Labcyte acoustic liquid handling enables biomarker detection by measuring multiple proteins with a MALDI mass spectrometer.

The Ongoing Collaboration Aims to Exploit the High Throughput, Robustness and Ease of Use of MALDI-TOF Instruments

At the 12th HUPO World Congress, Bruker Corporation (NASDAQ: BRKR) recently announced the start of a second-phase collaboration agreement with SISCAPA Assays Technologies, Inc. (SAT). The ongoing collaboration aims to exploit the high throughput, robustness and ease of use of MALDI-TOF instruments as an alternative to nano-LC-MS technology currently used in many SISCAPA assays.

AB SCIEX Proteomics Scientist Wins HUPO 2013 Science and Technology Award

The Human Proteome Organization (HUPO) recently awarded Christie Hunter, Ph.D, director of proteomics applications at AB SCIEX, its 2013 Science and Technology Award at an award ceremony during last week’s HUPO 2013 conference in Japan. Dr. Hunter was recognized for her contributions to the development and commercialization of a breakthrough approach for targeted proteomics. The analytical strategy of targeted proteomics was recently named “Method of the Year” by Nature Methods.

Targeted proteomics is a standardized, biological research workflow that focuses on reproducibly quantifying a specific subset of proteins within a sample. It generates data that is vital for biologists to answer hypothesis-driven, biological questions.

A decade ago, proteomics research was dominated by discovery workflows, which provided valuable information on a single sample but lacked the reproducibility to generate robust quantitation across a larger sample set. New innovation was needed at the time to move the field beyond simply producing large lists of identified proteins and toward providing highly quantitative answers.

This led to the development of a multiple reaction monitoring (MRM)-triggered, tandem mass spectrometry (MS/MS) workflow at AB SCIEX to rapidly create high sensitivity MRM assays to target peptides that are unique to their associated proteins. This workflow was made possible by the combination of triple quadrupole and linear ion trap functionality in a single system called the AB SCIEX QTRAP® System.

Dr. Hunter ‒ in collaboration with researcher Dr. Leigh Anderson, the founder of the Plasma Proteome Institute and head of SISCAPA Assay Technologies ‒ pioneered a workflow that applied MRM to the targeted quantification of proteins and peptides in plasma by mass spectrometry. In their initial publication[1], Dr. Hunter and Dr. Anderson demonstrated that a targeted workflow could be applied to multiplexed quantitation of proteins in human plasma with high reproducibility and high confidence in the results.

The impact of the paper resulted in broad adoption of the MRM technique around the world to accelerate the verification and validation of putative protein biomarkers, generating more than 800 citations, according to Google Scholar. Less than a decade after this important work, most proteomics laboratories today use a triple quadrupole-based mass spectrometer to perform MRM analysis.

“We congratulate Dr. Christie Hunter on receiving such a prestigious award from HUPO in recognition of her significant contributions to the rise of targeted proteomics as a viable technique to advance biomarker research,” said Dave Hicks, Vice President and General Manager of the Pharmaceutical and Academic Business at AB SCIEX.

“Dr. Hunter and her AB SCIEX colleagues continue to participate in exciting collaborations with leading proteomics researchers around the world to drive new innovations in software, chemistries and instrumentation that further expand quantitative proteomics workflows for the growing community of mass spectrometry users at large,” added Hicks.

Currently, Dr. Hunter is playing a pivotal role in the development of higher specificity workflows for targeted protein quantitation to overcome situations where sensitivity is limited by interferences or background. She is involved in the investigation of the utility of differential mobility separations for added selectivity of quantitation of peptides in complex mixtures. She is also working to enhance data-independent acquisition strategies, such as SWATHTM Acquisition, for quantitative proteomics to increase the multiplexing and reproducibility that can be achieved in a single experiment.
