Medical practitioners in Europe can use Bio-Rad’s CE-IVD marked QX200 Droplet Digital™ PCR (ddPCR™) System, IVD for highly-accurate diagnostic detection and quantification of nucleic acids, aiding clinical decision-making in the treatment of diseases ranging from cancer to transplant rejection and viral infection.

The system includes a QX200™ Droplet Generator, QX200™ Droplet Reader, and QuantaSoft™ software. The droplet generator and reader are CE-IVD marked for use in the European Union for in vitro diagnostics and are the only digital PCR instruments available for use in a clinical laboratory.

The QX200 Droplet Generator is used to partition a ddPCR reaction mixture into thousands of nanoliter-sized droplets. After endpoint PCR on a thermal cycler, droplets are read individually as they are streamed single file past a two-color optical detection system on the QX200 Droplet Reader. The PCR-positive and PCR-negative droplets are counted to provide absolute quantification of target DNA.
