Quantum-Si announces two customer posters to be presented at AACR meeting

Quantum-Si (QSI) announced that there will be two customer posters presented at the American Association of Cancer Research annual meeting on April 17-22, 2026 in San Diego, California. Poster Title: Combining deep mutational scanning and next-generation protein sequencing to harness dominant protein variants to develop DNA repair inhibitors: In the first poster, the researchers describe a complementary genetic and proteomic approach to find and model the behavior of therapeutics targeting DNA repair enzymes. Poster Title: High-resolution detection of post-translational modifications using single-molecule protein sequencing: In the second poster, the researchers demonstrated the ability to resolve and quantify multiple PTMs using Quantum-Si’s single-molecule protein sequencing technology. The authors suggested that the technology could be used to add proteoform characterization to biomarker studies, providing additional resolution not readily available in broad biomarker screening panels. The authors further concluded that they expect this technology could democratize advanced protein characterization, making the high-resolution detection of PTMs available to a broader scientific community.
