Quantum-Si Detects 18 Amino Acids Using Developmental Sequencing Kit

BRANFORD, Conn., Sept. 15, 2026 /CourierPR/ -- Quantum-Si, a company specializing in single-molecule protein sequencing, has announced a significant milestone in its research and development. The company has successfully demonstrated the detection of 18 out of the 20 amino acids using a developmental sequencing kit on its integrated Proteus™ instruments. This achievement is a crucial step towards the company’s goal of detecting all 20 amino acids by 2026.

Jeff Hawkins, the President and CEO of Quantum-Si, expressed his satisfaction with the progress.

The company's platform, which is designed to bring single-molecule protein analysis to every lab, has been praised for its ability to provide real-time, kinetic-based detection. This technology allows researchers to move beyond traditional, multistep workflows and directly access dynamic, functional protein insights with unparalleled resolution. By making protein analysis simpler, faster, and more informative, Quantum-Si aims to accelerate proteomic discoveries and improve the way we understand and interact with proteins.

Hawkins continued, "As we stated on our second quarter earnings call, the revised instrument timeline would allow us to progress further on amino acid recognizer development before finalizing our formulation for launch. The pace of improvement we are seeing continues to exceed our expectations, and by achieving detection of 18 amino acids now, we believe there is a potential to deliver all 20 amino acids in the commercial kit at launch."

The company's platform, known as the Proteus™, is expected to revolutionize the field of proteomics. By enabling real-time, kinetic-based detection, the Proteus™ aims to provide researchers with a more comprehensive understanding of protein dynamics. This technology could have significant implications for various fields, including drug discovery, disease diagnosis, and personalized medicine.

Quantum-Si's commitment to innovation is evident in its ongoing research and development efforts. The company's ability to detect 18 amino acids using its developmental sequencing kit on the Proteus™ instruments is a testament to its dedication to advancing the field of proteomics. As the company continues to work towards its goal of detecting all 20 amino acids, it remains optimistic about the potential impact of its technology on scientific research and medical applications.

In summary, Quantum-Si's achievement in detecting 18 amino acids using its developmental sequencing kit on the Proteus™ instruments is a significant milestone in the company's ongoing efforts to redefine protein analysis through single-molecule protein sequencing. The company's commitment to innovation and its goal of detecting all 20 amino acids by 2026 underscore its potential to transform the field of proteomics and drive advancements in scientific research and medical applications.
