Applying Recombinase-Aided Amplification to rapid food-safety testing
Hangzhou ZC Bio-Sci & Tech Co., Ltd. is an R&D-driven biotechnology company based in Hangzhou, China. We develop and apply Recombinase-Aided Amplification (RAA), an isothermal amplification technology, and supply RAA-based reagents, extraction kits and portable fluorescence instruments. Since September 2016 the company has focused RAA on food safety, launching the animal-species, foodborne pathogen and GMO detection series. All reagents are for research use only.

RAA Reagents, Kits and Instruments
Food Safety Detection Series (RUO)
Seventeen RAA fluorescent kits covering meat species, foodborne pathogens and GMO elements. 24 tests per kit, read directly from the amplification curve.
Genchek Fluorescence Analyzer
A portable eight-well analyzer with dual FAM and ROX channels, built-in reagent mixing and automatic reporting. Up to sixteen targets per run.
Need a target that is not in the catalog?
We develop custom RAA assays and OEM reagent formats for new targets, sample types and workflows — tell us what you need to detect.
Why Choose RAA
RAA combines the specificity of a molecular method with a workflow simple enough to run outside the laboratory.
5–15 Minutes to Result
A labelled fluorescent probe is read in real time, so a result is typically available within 5–15 minutes.
37–42 °C, No Thermal Cycler
The reaction is isothermal: a heat block, water bath or the Genchek analyzer is all the equipment required.
Lyophilised and Ready to Use
Reagents ship as freeze-dried pellets — easy to transport, simple to run and free from freeze–thaw loss.
