Droplet Digital PCR Assays

What is droplet digital PCR?

Droplet digital PCR technology is a digital PCR method utilizing a water-oil emulsion droplet system. Droplets are formed in a water-oil emulsion to form the partitions that separate the template DNA molecules. The droplets serve essentially the same function as individual test tubes or wells in a plate in which the PCR reaction takes place, albeit in a much smaller format. The massive sample partitioning is a key aspect of the ddPCR technique. The Droplet Digital PCR System partitions nucleic acid samples into thousands of nanoliter-sized droplets, and PCR amplification is carried out within each droplet. This technique has a smaller sample requirement than other commercially available digital PCR systems, reducing cost and preserving precious samples.

Advantages of ddPCR

  • Absolute quantification — ddPCR technology provides an absolute count of the target DNA copies of each input sample, without the need to run a standard curve, making this technology an ideal choice for target DNA measurement, viral load analysis, and microbial quantification.
  • Unparalleled accuracy — the large number of sample partitions provided by ddPCR can reliably measure small differences in the copy number of target DNA sequences between samples.
  • Eliminate PCR bias —reduce the error rate by eliminating the dependence of qPCR on amplification efficiency, so that small (1.2 times) differences can be detected.
  • Lower equipment costs — the emulsion-based reaction system means that the PCR reactions can be performed in a standard thermal cycler without complex chips or microfluidics.
