Quantum-Si detects 19 amino acids in Proteus program; targets all 20 by year-end 2026, launch in Q2 2027

Quantum-Si Inc

Quantum-Si demonstrated detection of 19 amino acids in its Proteus development program, up from the 18-amino-acid developmental kit presented at the 2026 World HUPO Congress.
Company is now deploying the 19-amino-acid capability into a developmental sequencing kit for routine use on integrated Proteus instruments by its R&D team.
CEO Jeff Hawkins said detection of all 20 amino acids is "well within reach by year-end 2026" and that the company is "growing increasingly confident" in hitting that milestone.
Management expects the 19-amino-acid capability to further increase Proteus sequencing performance and reiterated its commercial launch target for the second quarter of 2027.
