Quantum-Si (Nasdaq: QSI) announces a new preprint from Northwestern University researchers demonstrating the combined use of their Next-Generation Protein Sequencing™ (NGPS™) technology and Individual Ion Mass Spectrometry (I2MS) for analyzing interleukin-6 (IL-6), a key immune regulator and therapeutic target.

The study reveals that NGPS provided single amino acid resolution for IL-6 peptide fragments critical to receptor binding and function, while I2MS enabled intact proteoform detection and localized modifications, including glycosylation. The combination of these technologies offers comprehensive coverage of IL-6's structural and functional diversity, potentially advancing therapeutic research in complex diseases like cancer and autoimmune disorders.

Quantum-Si (Nasdaq: QSI) has announced the formation of its Scientific Advisory Board (SAB) to guide its next-generation proteomic technologies development. Dr. Gloria M. Sheynkman, Assistant Professor at the University of Virginia, has been appointed as Chair of the SAB. The board includes distinguished experts in proteomics, genomics, bioinformatics, chemistry, and engineering.

Key board members include Dr. Benjamin A. Garcia from Washington University School of Medicine, Dr. Bradley L. Pentelute from MIT, and Dr. Denis Zaccarin, former Senior VP of R&D at PacBio. The SAB will focus on shaping scientific strategy, identifying emerging trends, and strengthening scientific community engagement. They will also support Quantum-Si in prioritizing applications and fostering collaborations for their next-generation protein sequencing (NGPS) technology and Proteus™ platform.

Quantum-Si (Nasdaq: QSI) has announced a strategic partnership with IDEX Health & Science for the development and manufacturing of the optics module for their Proteus™ proteomics platform. IDEX Health & Science, a global leader in life science optics, fluidics, and microfluidics, will leverage their expertise through their Melles Griot and Semrock product lines to support the design, development, and manufacturing of the Proteus optics module.

The partnership aims to utilize IDEX's experience in complex optical systems for life sciences instrumentation, with QSI targeting to bring the novel platform to market by the second half of 2026. The collaboration is expected to accelerate scientific advancements and mitigate risks associated with timelines and product launches, ultimately contributing to breakthroughs in drug discovery, diagnostics, and human health.

Quantum-Si (Nasdaq: QSI) announced its participation in the Festival of Genomics UK, scheduled for January 29-30, 2025, at ExCeL London. Dr. Richard Broadhead will present on Next-Generation Protein Sequencing™ and its impact on proteomics research, featuring the company's Platinum® Pro platform.

The presentation will showcase three key advancements:

• A new Protein Barcoding Kit for multiplexed peptide barcoding
• Library Prep Kit V2 for streamlined sample preparation
• Integrated software for unified data generation and analysis

The technology enables single-molecule protein sequencing with high precision in protein identification and proteoform characterization, particularly in distinguishing proteoforms from amino acid changes, alternative splicing, and post-translational modifications. This capability enhances the integration of proteomic data with genomic and transcriptomic research.

Quantum-Si (QSI) has announced the granting of 44,893 restricted stock units (RSUs) to new employees through its 2023 Inducement Equity Incentive Plan. The grants, approved by the Compensation Committee of QSI's Board of Directors, serve as inducement material for new hires in accordance with Nasdaq Listing Rule 5635(c)(4).

The RSUs will follow a vesting schedule where 25% will vest on March 20, 2026, with the remaining portion vesting in 12 equal quarterly installments thereafter. Vesting is contingent upon continued employment with the company. These equity awards are exclusively granted to individuals who were not previously QSI employees, as part of their employment compensation package.

Quantum-Si (Nasdaq: QSI) has released a new preprint demonstrating the integration of their benchtop Platinum® instrument with protein barcoding technology. The study showcases a novel workflow that enhances multiplexed protein analysis with improved sensitivity and accessibility compared to traditional methods like mass spectrometry.

The research validated eight peptide barcodes designed for minimal detection bias and maximum sensitivity, featuring a streamlined workflow that reduces sample input requirements and hands-on time to under one hour. The system demonstrated a ten-fold dynamic range for detecting low-abundance proteins.

The combination of QSI's Platinum® Pro instrument with their protein Barcoding Kit offers advantages over DNA barcodes by providing direct quantitative readout of protein expression and localization. This advancement has potential applications in protein engineering, targeted drug delivery, and nucleic acid therapy development.
