Quantum-Si Inc — Investor Relations & Filings
Quantum-Si is a life sciences company focused on revolutionizing proteomics with its proprietary Next-Generation Protein Sequencing (NGPS™) platform. The company develops and markets the Platinum® and Platinum® Pro, the first commercial benchtop systems designed for single-molecule protein sequencing. By integrating a semiconductor chip with chemistry and biology, the platform provides real-time kinetic data with single-amino-acid resolution. This technology enables researchers to directly characterize proteins, identify variants, detect post-translational modifications (PTMs), and analyze proteoforms. The platform's applications support drug discovery, biomarker development, and antibody characterization, offering a simplified and accessible workflow to provide deeper proteomic insights compared to conventional methods.
