Copy Number Variation Analysis by Droplet Digital PCR.

The health impact of many copy number variants in our genome remains still largely to be discovered. Detecting and genotyping this often complex variation presents a technical challenge. Here we describe a 96-well format droplet digital PCR (ddPCR) protocol for genotyping a common copy variant in the human haptoglobin gene. ddPCR allows for high-throughput and accurate quantitation of gene copy numbers
