Description
Product Overview
The ProbeSeq Cardiac Troponin PeptideProbe™ System provides sequence-optimized peptide probes for selective recognition of cardiac troponin proteins (cTnI and cTnT), key biomarkers of myocardial injury and acute coronary syndrome. The system enables quantitative detection of cardiac injury markers associated with heart attack, cardiac stress, and cardiovascular disease.
This product supports development of protein-based diagnostic assays, biosensor platforms, and rapid point-of-care cardiac testing technologies. Peptide probes are engineered for high binding specificity, strong target affinity, 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 biomarker detection platforms.
Peptide Probe Technology Advantages
Peptide probes provide selective biomarker targeting with smaller molecular size compared to antibodies, enabling rapid binding kinetics, improved surface accessibility, and strong compatibility with biosensor platforms. They offer tunable affinity, stable performance, and reproducible signal generation for diagnostic assay development.
Molecular Detection Mechanism
The peptide probe selectively binds cardiac troponin proteins present in biological samples. Target binding generates a measurable signal through fluorescence, electrochemical response, or reporter activation depending on assay configuration.
The system supports quantitative detection of cardiac injury biomarkers and integration with rapid diagnostic workflows.
