About QSI
Quantum-SI Incorporated is a life sciences company. The Company has designed and developed a hardware, consumable and software solution to provide a solution for protein detection and analysis. It has developed a proprietary universal single-molecule detection platform enables Next-Generation Protein Sequencing (NGPS), the ability to sequence proteins. Its launched product consists of Platinum, the Platinum Analysis Software and consumables. Its flagship protein sequencing instrument, Platinum, is designed to make the power of single-molecule detection and NGPS accessible. Platinum is designed to provide a streamlined workflow compared to legacy MS workflows. Platinum uses its proprietary semiconductor chip that leverages time-domain sequencing with an initial focus on NGPS for an unbiased view of the proteome.
