Identify Peptides with Kinetic Signatures
Accelerating the Path to Discovery
A kinetic signature comprises the measurable characteristics of the series of dynamic recognizer events that uniquely identify a peptide.
Kinetic signatures change dynamically with alterations in amino acid and post-translational modifications (PTMs), providing a reliable means to accurately align peptides to their respective proteins.
Unlike other technologies, kinetic signatures offer a robust and confident approach to this alignment.
As Next-Gen Protein Sequencing becomes more widespread, kinetic signatures will be crucial to identifying every amino acid and every PTM, making Quantum-Si’s technology key to advancing our understanding of the proteome.

How NGPS Compares to Other Methods
NGPS Takes Mass Spectrometry to New Depths
Our technology identifies proteins using unique kinetic signatures based on the binding kinetics of amino acid recognition events. In contrast, mass spectrometry infers protein identification based on the mass:charge ratio, which may not distinguish protein variants of similar size.
