The detection of pathological variants in ß-amyloid proteins, especially those related to the amyloid precursor protein mutation, is pivotal for monitoring the progression of Alzheimer’s disease. While traditional methods often miss these subtle yet crucial mutations, Quantum-Si’s next-generation protein sequencing™ technology offers a revolutionary approach. It not only detects early signs of Alzheimer’s through amino acid mutations in ß-amyloid proteins but also detects the amyloid precursor protein mutation with precision. This advancement paves the way toward a deeper understanding of the disease’s progression and the potential for refining treatment strategies.

In this application note, we show how Quantum-Si’s single-molecule protein sequencing platform can effectively detect individual amino acid alterations linked to the progression and severity of Alzheimer’s.

Figure 1 demonstrates the structural alterations in ß-amyloid proteins that lead to the formation of pathological plaques, a hallmark of Alzheimer’s disease. The figure provides a detailed view of how these proteins undergo changes, exposing hydrophobic regions that induce aggregation and subsequent plaque formation. This data contributes to a molecular-level understanding of Alzheimer’s pathogenesis.

Here we demonstrate the pulse patterns observed in one ß-amyloid mutation, contrasting it with the patterns of the wild type. This figure offers visual data on how single point mutations impact the sequencing process and, consequently, our understanding of Alzheimer’s disease.

Focusing on a key mutation, we observed the distinctive kinetic influences on recognizer binding. The clear differences in pulse durations (PD) between the peptides of interest highlight the power of Quantum-Si’s Platinum instrument in differentiating the Alpha variant from the Delta and Omicron variants through a single mutation.

Here we highlight the differentiation of the Omicron variant from the Alpha and Delta variants based on the detection of a single peptide. The capability to identify variant-specific peptides contributes to the accurate and precise distinction of SARS-CoV-2 variants using Quantum-Si’s Platinum instrument.
