Description
Product Overview
The ProbeSeq Procalcitonin (PCT) Binding PeptideProbe™ System provides sequence-optimized peptide ligands for selective detection of procalcitonin, a clinically established biomarker for systemic bacterial infection and sepsis progression. The system enables quantitative measurement of PCT levels in biological samples to support research in infection diagnosis, antimicrobial stewardship, and inflammatory response monitoring.
This product supports development of rapid infection diagnostics, sepsis screening assays, and point-of-care testing technologies. Peptide probes are engineered for high binding specificity, rapid target recognition, 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 inflammatory biomarker panels.
Peptide Probe Technology Advantages
Peptide binding probes enable direct biomarker recognition with high structural stability and reproducible performance. Compared to antibody-based detection methods, peptide probes offer improved chemical robustness, tunable affinity, rapid binding kinetics, and strong compatibility with biosensor platforms and surface immobilization strategies.
Molecular Detection Mechanism
The peptide probe selectively binds procalcitonin molecules through sequence-specific molecular interactions. Target binding produces a measurable signal change through reporter activation, fluorescence detection, or electrochemical response depending on assay configuration.
The system supports quantitative monitoring of infection biomarkers and real-time inflammatory response analysis.
