Description
Product Overview
The ProbeSeq MMP Cleavable PeptideProbe™ System provides sequence-optimized peptide substrates for selective detection of matrix metalloproteinase activity, including MMP-2, MMP-9, and related proteases. The system enables quantitative measurement of protease activity associated with cancer progression, tissue remodeling, inflammation, and disease pathology.
This product supports development of enzyme-based diagnostic assays, biosensor platforms, and point-of-care detection technologies. Peptide probes are engineered for high cleavage specificity, rapid enzymatic response, and stable signal generation across fluorescence, electrochemical, and microfluidic detection formats.
The system is compatible with molecular diagnostics workflows, lab-on-chip devices, and multiplex disease detection platforms.
Peptide Probe Technology Advantages
Peptide cleavage probes enable direct measurement of enzyme activity rather than simple biomarker presence, providing higher functional relevance in disease detection. Compared to antibody-based detection, peptide probes offer rapid kinetics, tunable specificity, strong biosensor compatibility, and reproducible signal generation.
Molecular Detection Mechanism
The peptide probe contains an MMP-specific cleavage sequence that is selectively hydrolyzed by target proteases. Enzymatic cleavage generates a measurable signal change through reporter release, fluorescence activation, or electrochemical response.
The system supports real-time monitoring of protease activity and quantitative analysis of disease-associated enzymatic processes.
Target Design Strategy
Peptide sequences are optimized for selective recognition and cleavage by disease-relevant MMP enzymes.
