Quantum-Si interim Proteus data: 30x more alignments, 4.8x lower false discovery rate vs Platinum Pro

Quantum-Si Inc

Proteus delivered a median 4,094,411 alignments per single chamber versus 135,901.5 for Platinum Pro (30.1x), identifying all six control peptides in every run.
Median false discovery rate was 1.36% on Proteus vs 6.58% on Platinum Pro, a 4.8-fold improvement; the developmental kit detects 18 amino acids.
In a 24-protein panel not previously sequenced on either platform, Proteus detected all 24 proteins vs an average of 20.3 on Platinum, and 269,864 amino acids per run vs 63,366 (4.3x).
Company projects a full four-chamber Proteus run could yield roughly 60x more alignments than a two-chamber Platinum Pro run; instrument, consumable and software remain unoptimized.
CEO Jeff Hawkins presents the interim results at World HUPO 2026 in Singapore on Sept. 29, 2026 at 12:15 p.m. SGT in Room 330.
