Description
Product Overview
The ProbeSeq SARS-CoV-2 Spike PeptideProbe™ System provides sequence-optimized peptide ligands engineered for selective binding to the SARS-CoV-2 spike (S) protein. The system enables sensitive viral target recognition for diagnostic assay development, infection monitoring, and rapid detection technologies.
This product supports development of peptide-based viral detection platforms, biosensor devices, and microfluidic diagnostic systems. Peptide probes are designed for high target affinity, structural stability, and reproducible signal generation across fluorescence, electrochemical, and lateral-flow detection formats.
The system is compatible with multiplex respiratory pathogen panels and portable diagnostic platforms.
Peptide Probe Technology Advantages
Peptide probes provide rapid target recognition with smaller molecular size compared to antibodies, enabling improved surface accessibility, faster binding kinetics, and strong compatibility with biosensor platforms. They support stable performance and scalable manufacturing for diagnostic assay development.
Molecular Detection Mechanism
Peptide probes selectively bind SARS-CoV-2 spike protein through sequence-specific molecular interactions. Target binding produces a measurable signal through reporter activation, fluorescence detection, or sensor surface response depending on assay configuration.
The system supports direct viral detection or signal amplification workflows.
