Protillion's transformational drug discovery and optimization platform generates precise protein data with the scale to bridge advanced computation and real-world results

Platform can identify and optimize new protein therapeutics to accelerate R&D productivity

BURLINGAME, Calif., Dec. 19, 2022 /PRNewswire/ -- Protillion Biosciences, a privately held biotech company working to identify and optimize new protein therapeutics and accelerate biologic research and development productivity, today announced the completion of an $18 million Series A financing from ARCH Venture Partners and Illumina Ventures. The Company's platform enables its commercial drug discovery partners to perform true quantitative analysis on complete protein libraries, producing actionable insights in days; a process that can take months using current industry best practices. Protillion's proprietary technology can generate and analyze massive experimental datasets at perfect amino acid resolution, enabling novel machine-learning approaches to antibody and binder discovery.

The funds will be used to scale the Company's unique hardware infrastructure and development teams to meet the demand for future partnerships in therapeutic antibody discovery. Protillion is actively identifying opportunities to supercharge discovery processes for potential pharma partners through its cutting-edge technology.

"For the first time, quantitative binding measurements for millions of biologic candidates can be seen up-front, and big data is available much earlier in the discovery process," said Protillion co-founder and CEO Curtis Layton, Ph.D. "Our mission is to find better medicines via transformative technology that enables us to identify the best therapeutic molecules every time."

Launched in 2019, Protillion's technology was developed by Dr. Curtis Layton in the Stanford University laboratory of co-founder William Greenleaf, Ph.D., to pioneer a new approach to high-throughput interrogation of biochemical systems. Dr. Layton developed ultra-high-impact technology approaches for drug discovery by uniting a broad array of interdisciplinary fields, including protein engineering, next-generation sequencing technology, molecular biology, in vitro transcription and translation, computational biology, software development, and various engineering disciplines.

"Protillion's technology enables exquisite exploration of protein sequence space, facilitating a generational shift in high-throughput protein discovery," said Sean Kendall, Partner at ARCH. "It bridges key gaps between computational methods and real-world performance, opening the door to the rapid development of novel and truly optimized biologics."

In addition to Dr. Layton, co-founders of Protillion include David Walt, Ph.D., of the Wyss Institute at Harvard University, Brigham and Women's Hospital, and Harvard Medical School. Dr. Walt is a pioneer of single-molecule detection and analysis techniques and the scientific founder of Illumina, Inc., Quanterix Corp., and several other cutting-edge life science companies. He will serve on Protillion's Board of Directors. William Greenleaf, Ph.D., of the Stanford University School of Medicine is a member of Bio-X, the Biophysics Program, the Biomedical Informatics Program, and the Cancer Center. His prolific lab has generated many high-impact tools to better understand complex biological systems.

About Protillion Biosciences

Protillion Biosciences is a Stanford University spinout commercializing disruptive technology for therapeutic antibody and binder discovery. While current state-of-the-art antibody discovery and optimization techniques may take months of laborious laboratory procedures executed by highly-skilled practitioners, Protillion's high throughput instrumentation can characterize the binding affinity on the order of 1 million antibody variants in a 2-day automated run. Our unique approach enables the identification of better antibody candidates on an exponentially faster timeline. For more information, visit www.protillion.com.
