RPA Isothermal Amplification

Proprietary constant-temperature system removes PCR thermal cycling for much faster turnaround.

Pre-mixed lyophilized reagents enable one-step sample prep, easy to use for non-specialists.

Works like a "precision magnifier" — targets only the intended pathogen, no cross-reactivity, no false calls.

Detects as little as 1 copy/μL of trace pathogen, even during incubation, for fewer missed detections.

CRISPR-Enhanced Sensitivity

Fully automated sample-to-result workflow requires no specialized labs or trained technicians.

Closed reaction system prevents cross-contamination, reliable for clinics, farms, hubs and more.

Lab-Free On-Site POCT

Unlike assemblers, we produce our own key enzymes and reaction reagents. This ensures absolute supply stability and maximizes cost advantages for our partners.
