When combined with the Version 4 Sequencing Kit which was launched in September 2025, the Company expects users will see significant improvements analyzing scarce biologic samples, complex mixtures, and detecting low abundance biomarkers.\n<\/p>\n<p>\nThe Version 3 Library Preparation Kit is a significant improvement over the current kit and requires 200 ng or less of total protein input. This represents a 100-fold improvement over the current kit. Furthermore, data from internal validation studies demonstrates that the Version 3 Library Preparation Kit enables detection of proteins in mixtures with as little as 1-2 ng of protein which equates to less than 1% relative abundance in a sample mixture. These capabilities will greatly increase the ability for users to process scarce biologic samples and detect low abundance proteins in applications such as signaling pathways.\n<\/p>\n<p>\nIn addition to the launch of the Version 3 Library Preparation Kit, the Company also announced the release of a suite of data analysis tool enhancements. The new analysis tools unlock the detection of an additional amino acid (methionine), further increase peptide alignment accuracy and improve overall protein inference performance and interpretability.\n<\/p>\n<p>\n\u201cThe Version 3 Library Prep Kit is by far the most sensitive kit the Company has released to date. With the ability to sequence proteins with as little as 1-2 ng of input, our customers will be able to explore low abundance biomarkers and biomarker panels that have been previously inaccessible with our technology,\u201d said Jeff Hawkins, President and Chief Executive Officer of Quantum-Si. \u201cIn addition, the new data analysis tools continue to enhance the accuracy and robustness of the data our customers are generating and expands the amino acid coverage to 15 amino acids on path to our goal of demonstrating detection of all 20 amino acids in 2026.\u201d\n<\/p>\n<p><b>About Quantum-Si Incorporated<br \/>\n<br \/><\/b>Quantum-Si is transforming proteomics with a benchtop platform that brings single-molecule protein analysis to every lab, everywhere. The Company\u2019s platform enables real-time kinetic-based detection and 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 is accelerating proteomic discoveries to improve the way we live.
