Quantum-Si Inc. (QSI) shares surged 5.3% in after-hours trading following the release of a new preprint showcasing the company's innovative protein barcoding workflow for multiplexed protein analysis.
The study highlights the integration of Quantum-Si's benchtop Platinum® instrument with a novel protein barcoding approach, offering a sensitive and accessible solution for proteomics research. Key features include:
- Validated peptide barcodes with minimized detection bias and maximized sensitivity - Streamlined workflow reducing sample input and hands-on time - Demonstrated ten-fold dynamic range for robust detection of low abundance proteinsAccording to CEO Jeff Hawkins, the combination of Platinum® Pro and the protein Barcoding Kit enables "unmatched sensitivity and accessibility in proteomics research." The study underscores the advantages of protein barcode sequencing over DNA barcodes, providing a direct quantitative readout of protein expression and localization.
