RAA Technology

Rapid testing with ZC Bioscience

Recombinase-Aided Amplification binds the primer to a recombinase, opens the template strand at 30–42 °C and copies the target exponentially — no thermal cycler required. A labelled fluorescent probe reads the reaction as it runs.

Reagents arrive lyophilised and ready to use.
