Description
The ProbeSeq Influenza A CRISPRDetect™ Guide RNA System provides sequence-optimized CRISPR guide RNA constructs for programmable recognition of Influenza A viral RNA. The system directs Cas enzymes to conserved genomic regions of the virus, enabling highly specific nucleic acid detection and rapid signal generation for molecular diagnostic development.
This product supports development of respiratory infection detection platforms, multiplex pathogen panels, and portable diagnostic technologies. Guide RNAs are engineered to promote strong target hybridization, efficient Cas activation, and stable performance across fluorescence, electrochemical, and lateral-flow readout formats.
The system is intended for research laboratories developing CRISPR-based diagnostics, point-of-care testing technologies, and microfluidic molecular detection systems.
Molecular Detection Mechanism
Target recognition occurs through CRISPR guide RNA hybridization to complementary Influenza A RNA sequences. Upon target binding, Cas enzyme activation triggers catalytic cleavage of reporter substrates or signal molecules, producing a measurable detection output.
The system supports direct viral RNA detection or amplification-assisted workflows. When combined with RT-LAMP or recombinase polymerase amplification (RPA), detection sensitivity can reach very low viral copy numbers. Guide RNA design promotes stable Cas complex formation while minimizing non-specific activation.
Target Design Strategy
Guide RNA sequences are selected from conserved Influenza A genomic regions such as matrix (M), nucleoprotein (NP), and hemagglutinin (HA) gene segments to ensure robust detection across circulating strains.
Design optimization prioritizes:
High sequence specificity and mismatch discrimination
Broad strain coverage across Influenza A subtypes
Minimal cross-reactivity with Influenza B and other respiratory viruses
Thermodynamic stability of guide–target hybridization
Compatibility with multiplex respiratory detection panels
Custom strain-specific or subtype-selective probes are available.
Assay Workflow Integration
The CRISPRDetect™ system supports flexible workflows including RNA extraction or crude sample preparation, optional nucleic acid amplification, CRISPR reaction assembly, and signal readout using compatible detection platforms.
Detection can be performed using fluorescence readers, electrochemical biosensors, lateral-flow systems, or microfluidic devices. Typical reaction input volumes range from approximately 5–20 µL depending on assay configuration.
