Platinum by Quantum-Si is revolutionizing proteomics with its Next Generation Protein Sequencing (NGPS) technology. This benchtop system brings single-molecule protein sequencing into focus, enabling researchers to achieve a level of resolution and insight that was previously unattainable. Platinum utilizes N-terminal amino acid (NAA) recognizers to sequence proteins with high precision, allowing for the identification of proteoforms, post-translational modifications (PTMs), and other variations that are critical to understanding biological systems.
What makes Platinum truly transformative is its simplicity. Unlike traditional proteomics setups requiring expensive and complex instrumentation such as mass spectrometers, Platinum requires only the sequencer itself and basic laboratory equipment to establish a fully functional proteomics lab. This accessible approach lowers the barriers to entry for protein analysis, making cutting-edge research feasible for a wider range of labs.
At the heart of Platinum is its innovative approach to sequencing. By systematically cleaving amino acids and recording light-based kinetic profiles, the system generates unique signatures for each peptide. This process provides unprecedented accuracy in identifying protein sequences, even in complex mixtures. Platinum also boasts integrated, cloud-based data analysis tools, ensuring seamless and efficient interpretation of results.
Designed with accessibility and automation in mind, Platinum eliminates many of the bottlenecks associated with traditional proteomic techniques. Its compact footprint and simplified workflows make it a perfect fit for labs of all sizes.
At the core of Platinum’s technology are molecules called recognizers, which bind to specific amino acids and generate unique kinetic signatures. These recognizers enable the system to identify and sequence proteins with unmatched precision and efficiency.
