The future of qPCR is here, and it’s digital.
Bio-Rad’s QX100 Droplet Digital PCR system provides an absolute measure of target DNA molecules with unrivaled precision and accuracy. The QX100 system partitions each sample into 20,000 individual nanoliter-sized droplets. PCR-positive and PCR-negative droplets from every sample are then counted to provide absolute target quantification in digital form. The QX100 system provides a revolutionary approach to target DNA quantification. Click here for more information or contact your Bio-Rad Sales Representative to learn more.
The QX100™ ddPCR™ system lets you:
- Detect rare target sequences with unmatched sensitivity for cancer and viral research
- Measure small differences in target copy number variations (down to 1.2x differences)
- Determine absolute gene expression levels without a standard curve or the ΔΔCq method
