Combined Workflow of Proteograph™ XT Assay and Thermo Scientific™ Orbitrap™ Astral™ Mass Spectrometer Robustly Identifies over 13,000 Protein Groups Across a Study of 2,840 Subjects

REDWOOD CITY, Calif., June 02, 2024 (GLOBE NEWSWIRE) — Seer, Inc. (Nasdaq: SEER), a leading life sciences company commercializing a disruptive new platform for proteomics, announced today that PrognomiQ has completed the largest and deepest unbiased mass spectrometry plasma biomarker study to date utilizing the Seer Proteograph™ Product Suite and Thermo Fisher Scientific’s Thermo Scientific™ Orbitrap™ Astral™ mass spectrometer. This pioneering research involved a multi-cancer case-control cohort of 2,840 subjects, achieving the detection of over 13,000 protein groups in plasma across the study, with an average of over 8,200 protein groups in plasma per sample.

PrognomiQ collected blood samples across 77 clinical sites in the U.S., and processed plasma samples using their in-house Seer Proteograph SP100 instruments and XT assays. The resulting peptides were sent to the Seer Technology Access Center (STAC) in Redwood City to be analyzed using the Orbitrap Astral mass spectrometers. This study demonstrates the combined power of two leading proteomics technologies and their ability to efficiently and rapidly conduct deep, unbiased plasma proteomics studies at scale. PrognomiQ’s findings highlight unprecedented depth and sensitivity in proteomics, unlocking significant biological insights for early cancer detection.

“This study represents a significant milestone in cancer biomarker research. The depth and breadth of data obtained have the potential to transform early cancer detection and build on earlier studies with the Seer Proteograph™ Product Suite,” said Bruce Wilcox, Chief Technology Officer of PrognomiQ.

Dr. Wilcox will present the complete study results in an oral presentation at the American Society of Mass Spectrometry (ASMS) Conference on Thursday, June 6 at 8:30 a.m. Pacific Time after sharing some findings at the user breakfast meeting hosted by Thermo Fisher on Sunday, June 2 at 8:00 a.m. Pacific Time.

“We are excited to see the impact that the Orbitrap Astral has on deep unbiased biomarker discovery in such a comprehensive study,” said John Lesica, President, Chromatography and Mass Spectrometry at Thermo Fisher. “Our collaboration with Seer to launch the STAC underscores our commitment to advancing proteomics research and, ultimately, its application in healthcare.”

“This study represents the largest and deepest unbiased proteomics study reported to date, and it is uniquely enabled by the Proteograph XT Assay kit and the Orbitrap Astral mass spectrometer,” said Omid Farokhzad, CEO and Chair of Seer. “The STAC provides a robust and cost-effective service for academic and biopharma customers to access the power of our combined platforms, enabling a new standard for proteomics discovery and translational research.”
