Droplet Digital PCR Technology and Workflow

The QX200 Droplet Digital PCR System consists of two instruments, the QX200 Droplet Generator and the QX200 Droplet Reader, and their associated consumables.

The QX200 Droplet Generator is used to partition ddPCR reaction mix into thousands of nanoliter-sized droplets. After PCR on a thermal cycler, droplets from each sample are analyzed individually on the QX200 Droplet Reader. Droplets are read well by well as they are streamed single file past a two-color optical detection system in a serial manner. Up to 96 samples can be processed per run. The PCR-positive and PCR-negative droplets are counted to provide absolute quantification of target DNA in digital form. Alternatively, amplified products can be extracted from droplets following PCR for downstream applications, such as sequencing or cloning.

Additional Instruments

The QX200 Droplet Digital PCR System requires the use of the PTC Tempo Deepwell Thermal Cycler or C1000 Touch Thermal Cycler with 96–Deep Well Reaction Module and the PX1 PCR Plate Sealer.
