Quantum-Si's Proteus Prototype Outperforms Platinum Pro in Customer Sample Testing
Event summary
- Quantum-Si completed sequencing of multiple customer samples on the Proteus prototype system in April 2026.
- Proteus prototype demonstrated significantly improved amino acid coverage, longer read lengths, and greater sequencing output compared to Platinum Pro.
- Testing used Version 3 Library Preparation Kit and a developmental sequencing kit with the latest amino acid recognizer set.
- Quantum-Si plans to expand customer sample testing through a formal pre-launch evaluation program.
The big picture
Quantum-Si's successful testing of customer samples on the Proteus prototype marks a critical step in its mission to redefine protein analysis. The prototype's superior performance over the existing Platinum Pro system positions Quantum-Si to capture a larger share of the proteomics market, which is increasingly demanding higher-resolution, single-molecule protein sequencing capabilities. The company's ability to scale production and meet customer demand will be key to sustaining its competitive edge in this rapidly evolving sector.
