Droplet Digital PCR for Gene Copy Number Variation


Copy number variations (CNVs), from single gene to segmental duplications, are increasingly recognized as critical features of the human genome. Droplet Digital PCR (ddPCR) technology enables accurate and reproducible copy number determination via a simple, cost-effective workflow amenable to high throughput.

Samples with copy numbers of 5 vs. 6 are easily resolved, as are samples that are heterogeneous for gene amplifications. This technology has immediate implications for researchers interested in resolving somatic mosaicism, tumor heterogeneity, or other applications where fine quantitative discrimination is essential.

The QX200 Droplet Digital PCR System, Bio-Rad's second-generation digital PCR system, provides absolute quantification of target DNA or RNA molecules using EvaGreen or TaqMan hydrolysis probes, yielding unmatched sensitivity and precision for a wide variety of applications.
