Expert Statements
Jeff Hawkins, President and Chief Executive Officer of Quantum-Si
“Demonstrating detection of 19 amino acids is an important step toward our goal of detecting all 20 amino acids by the end of 2026.”
Jeff Hawkins, President and Chief Executive Officer of Quantum-Si
“We are now focused on deploying this capability into a developmental sequencing kit for use by our R&D team.”
Jeff Hawkins, President and Chief Executive Officer of Quantum-Si
“Given the pace of progress in our recognizer program, we are growing increasingly confident in our ability to demonstrate detection of all 20 amino acids by year-end 2026.”
Jeff Hawkins, President and Chief Executive Officer of Quantum-Si
“At World HUPO, we demonstrated that Proteus delivered significant improvements across every key measure of sequencing performance using a developmental kit that detects 18 amino acids.”
Jeff Hawkins, President and Chief Executive Officer of Quantum-Si
“Once this 19-amino-acid capability is deployed into a developmental sequencing kit, we expect it to even further increase Proteus sequencing performance.”
Jeff Hawkins, President and Chief Executive Officer of Quantum-Si
“Combined with the significant performance improvements presented at World HUPO, this progress further strengthens our confidence in the continued advancement of the Proteus platform toward commercial launch in the second quarter of 2027.”
BRANFORD, Conn., Oct. 08, 2026 (GLOBE NEWSWIRE) -- Quantum-Si Incorporated (Nasdaq: QSI) (“Quantum-Si,” “QSI” or the “Company”), a proteomics company redefining protein analysis through single-molecule protein sequencing, today announced that it has demonstrated detection of 19 amino acids in its Proteus™ development program and is now working to deploy that capability into a developmental sequencing kit for routine use on integrated Proteus instruments. Building on the interim Proteus results presented at the 2026 World HUPO Congress, this latest milestone reflects continued progress in the Company’s amino acid recognizer program and reinforces its confidence that detection of all 20 amino acids is well within reach by year-end 2026.
“Demonstrating detection of 19 amino acids is an important step toward our goal of detecting all 20 amino acids by the end of 2026,” said Jeff Hawkins, President and Chief Executive Officer of Quantum-Si. “We are now focused on deploying this capability into a developmental sequencing kit for use by our R&D team.
