Proteus Delivers 30x More Alignments
In a control peptide study, Proteus produced a median of 4,094,411 alignments per chamber versus 135,901.5 for Platinum Pro — a 30.1x improvement.
-
4.8x Lower False Discovery Rate
Proteus achieved a 1.36% median FDR compared to 6.58% for Platinum Pro, indicating substantially higher sequencing accuracy.
-
Full-Run Projection of 60x Improvement
Extrapolating single-chamber results, a full four-chamber Proteus run could deliver approximately 60x more alignments than a two-chamber Platinum Pro run (16.4M vs 0.27M).
-
Superior Protein Mixture Coverage
In a 24-protein panel, Proteus detected all 24 proteins (vs 20.3 average on Platinum) and 4.3x more amino acids per run (269,864 vs 63,366).
Analysis · QSI · Industrial Applications And Services
At World HUPO 2026, Quantum-Si presented interim development data for its next-generation Proteus protein sequencing platform, revealing dramatic performance gains over the current Platinum Pro instrument. Proteus delivered 30x more alignments per chamber, a 4.8x lower false discovery rate, and 4.3x more amino acid coverage. These results matter because Proteus is the company's core growth bet — its launch has been delayed to Q2 2027, and the company is fighting a Nasdaq delisting notice with revenue of only $344,000 last quarter. Strong interim data validates the platform's technical promise and could help the company raise capital or regain investor confidence, but the instrument is still in development and not yet fully optimized.
