SCIEX partners to improve depth of proteome coverageSCIEX 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.
How it’s done!Pressure Cycling Technology (PCT) Sample Preparation Systems utilize controlled cycles of pressure to break apart the tissue samples. Scientists see faster and improved sample processing, and a higher quality of results. When combined with SWATH® Acquisition, high quality protein quantitation results can be obtained on 1000s of proteins in 100s of samples. Thus, combining SWATH® Acquisition with PCT sample preparation makes reproducible proteome research feasible across the enormous diversity of complex biological samples.
Who developed it and Why?PCT-HD was developed by PBI scientists and engineers in collaboration with Professor Ruedi Aebersold and Dr. Tiannan Guo at ETH Zurich. Drs. Aebersold and Guo combined PCT-HD sample preparation with SCIEX’s SWATH Mass Spectrometry in an effort to standardize the protocol for reproducible, comprehensive quantitation from complex samples. This unique protocol is capable of processing up to 16 samples in six hours1, much faster than current methods.
“By addressing the significant challenges inherent in complex sample preparation to reproducibly analyze thousands of proteins in hundreds of samples, PCT-SWATH accelerates proteomics research in biologically and clinically relevant contexts,” states Dr. Aebersold. “This should increase the productivity of biomarker research, potentially leading to significant improvements in healthcare, including personalized medicine.
Why PCT-HD with SWATH®Acquisition?
The Goal and SolutionOur goal is to industrialize proteomics by enabling efficient, reproducible and automated workflows specifically targeting analysis of small tissue samples for life science research. As the promise of precision medicine research continues to evolve, researchers will need powerful tools and application support to perform the Omics research that creates the scientific foundation of precision medicine. This solution from SCIEX and PBI is expected to significantly expand the footprint of MS-based quantitation workflows in clinical research settings worldwide.
Most recently, the Aebersold lab has combined the latest PCT technology with SWATH® acquisition to achieve a 40% increase in peptide quantitation over traditional methods.1 This means deeper proteome coverage with less sample input requirements.
To learn more about how the PCT sample prep workflow, our partners at PBI have recorded a short video.

Depending on the samples that you are running on the system, it is possible for the Echo MS electrode to become dirty or occluded over time. Below are two different cleaning strategies that will be helpful for you to maintain your system and keep your electrodes running well.
Developing an analytical method can be one of the most rewarding jobs an analytical scientist can do, but it can also be one of the most complex and frustrating. To help guide your practical experiments and thought processes we spoke to Kean Woodmansey to benefit from his experience.
As analytical organizations grow, there is an even greater need to train scientists and operators more consistently to meet tight deadlines, handle increasing samples, and meet data quality expectations. A high rate of employee turnover also affects the productivity of labs worldwide. Consistent training helps today’s labs stay competitive, whether the goal is sample throughput, therapeutic development, or publication.
