SCIEX, a global leader in life science analytical technologies, presents the ZenoTOF 7600 system, a new accurate mass LC-MS/MS instrument. The new system enables scientists to identify, characterize and quantify molecules better than ever before by generating data that has been previously unattainable. This breakthrough will solve real analytical challenges and help advance the development of new precision diagnostics and biotherapeutics.
“Only a step-change in innovation will meet the evermore ambitious goals of scientists around the world. This new platform and mindset in accurate mass has the power to change people’s perspective and profoundly impact lives.”
- Joe Fox, President of SCIEX.
The ZenoTOF 7600 system includes the proprietary Zeno trap and electron activated dissociation (EAD) fragmentation for the first time in a commercial instrument. Zeno trap pulsing overcomes the traditional duty cycle challenges of orthogonal TOF technology, delivering up to 20x the sensitivity and enabling the routine detection of important low-abundant molecules. In combination, tunable EAD fragmentation ensures novel structural information can be extracted and quantified from diverse compound types – a capability that is not possible by using high resolution alone.
“The fact that we can now add alternative fragmentation to our existing workflows, and with higher sensitivity at the same time is really extraordinary. It's a real change in how data are generated and the biological insight we can get.”
- Matt Champion, Associate Professor, University of Notre Dame.
Extraordinary sensitivity in combination with EAD fragmentation will push new boundaries in biomarker discovery and biopharmaceutical therapies
To advance the detection and treatment of disease, it is critical to understand how thousands of proteins, lipids and metabolites in the body are regulated and modified. Biomarkers, the molecules that change when we are ill, are used by doctors as the “canary in the coal mine” warning system. So far, scientists have only scratched the surface in biomarker discovery. The ZenoTOF 7600 system will help scientists uncover more and better biomarkers, bringing us closer to true precision medicine where the right drug is given to the right patient at the right time.
Compared to previous systems, the ZenoTOF 7600 system can quantify up to 40% more proteins and analyze samples 5x faster for large biobank studies. In addition, EAD fragmentation brings new capabilities to understand how the proteins are post-translationally modified – an important but challenging area in biomarker research.
“The ability to exactly tailor kinetic energy for EAD optimizes the MS/MS spectra and maximizes quantification accuracy. The use of Zeno trap pulsing provides significant gains in sensitivity, further improving the utility of this approach for characterizing PTMs.”
- Birgit Schilling, PhD, Associate Professor, Director of the Mass Spectrometry Center, The Buck Institute
The ZenoTOF 7600 system is transformational for lipidomics and can fully characterize an individual lipid from a single spectrum using EAD fragmentation. This will enable the discovery of novel lipid markers for cancer and inflammatory disease, precisely identifying and quantifying individual species that has been previously impossible.
“We were never able to characterize all the way down to the double bond position of lipid species, or identify the exact position of side chains. I see the ZenoTOF 7600 system as a really important advancement in being able to completely profile the lipidome from the top to the bottom.”
- James Cox, Research Associate Professor, University of Utah.
To bring life-saving next-generation biopharmaceutical therapies to market quickly and safely, critical quality attributes must be rapidly and comprehensively analyzed. For the first time, EAD fragmentation allows biopharmaceutical scientists to precisely detect and quantify protein glycosylation patterns and differentiate isomeric amino acids. Both are critical to ensuring that therapies are safe and do not produce adverse reactions.
“As biopharma scientists seek to develop more complex and sophisticated biotherapeutics, the challenge of analytics also becomes more complex. The ability of EAD to routinely and precisely characterize these biologics will change the game and make therapies accessible to patients much faster.”
