Quantum-Si

About

Quantum-Si, The Protein Sequencing Company™, is focused on revolutionizing the growing field of proteomics. Founded in 2013 by Jonathan Rothberg, the company is dedicated to making protein sequencing accessible to the broader proteomics and multiomics community. Quantum-Si has designed and developed a comprehensive solution encompassing hardware, consumables, and software to facilitate advanced protein detection and analysis. Their flagship products, Platinum and Platinum Pro, represent the world's first Next-Generation Protein Sequencers™ (NGPS™), enabling single-molecule, single-amino-acid resolution. This innovative technology integrates biology, chemistry, artificial intelligence, and semiconductor technology to empower researchers to study proteins at an unprecedented scale. The company's proprietary universal single-molecule detection platform is at the core of its NGPS™ technology, which allows for the sequencing of proteins by leveraging time-domain sequencing on a custom semiconductor chip. This approach provides a streamlined workflow compared to traditional methods like mass spectrometry and Edman degradation, offering an unbiased view of the proteome. Quantum-Si's technology is designed to identify protein variants and modifications with high precision, which is critical for advancing scientific research, drug discovery, and diagnostics. By making NGPS™ accessible to every lab, Quantum-Si aims to drive groundbreaking advancements and fuel a new era of biological understanding, moving beyond genomics to focus on the complex world of proteins and their role in health and disease. The company is publicly traded on Nasdaq under the ticker QSI and is headquartered in Branford, Connecticut.
