Quantum-Si Demonstrates Automated Protein Sequencing Workflow
Event summary
- Quantum-Si achieved a fully automated protein sequencing workflow on integrated Proteus instruments using a developmental KinetIQ Array.
- The KinetIQ Array now detects 17 amino acids, a four-month improvement from detecting 15 in December 2025.
- The demonstration involved a user-initiated process, with the instrument handling sample loading and data acquisition.
- Quantum-Si anticipates early access customers will have hands-on experience with the technology this summer.
The big picture
Quantum-Si's demonstration of a fully automated protein sequencing workflow represents a significant step towards commercializing its Proteus platform, which aims to disrupt the proteomics market. The rapid improvement in amino acid detection (adding two new amino acids in four months) suggests a potentially accelerated development cycle, but also highlights the challenges of scaling a complex technology. The company's success hinges on its ability to ramp up manufacturing and secure widespread adoption among researchers.
What we're watching
- Manufacturing Scale
- The ability to rapidly expand Proteus instrument production will be critical to meeting anticipated demand and achieving commercial launch by the end of 2026, given the reliance on manufacturing partners.
- Customer Adoption
- Early access customer feedback and adoption rates will be a key indicator of the technology's utility and potential for broader market penetration beyond the initial user group.
- Competitive Landscape
- The pace at which competitors develop and deploy similar automated protein sequencing solutions will determine Quantum-Si's long-term market share and pricing power.
