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 dd. PCR 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. Sample partitioning is the key to droplet digital PCR. In traditional PCR, a single sample offers only a single measurement, but in Droplet Digital PCR, the sample is partitioned into 2.

PCR technology uses a combination of microfluidics and proprietary surfactant chemistries to divide PCR samples into water in oil droplets Hindson et al. The droplets support PCR amplification of the template molecules they contain and use reagents and workflows similar to those used for most standard Taq. Man probe based assays. Following PCR, each droplet is analyzed or read to determine the fraction of PCR positive droplets in the original sample. These data are then analyzed using. Poisson statisticsto determine the target DNA template concentration in the original sample. Droplet Digital PCR surpasses the performance of earlier digital PCR techniques by resolving the previous lack of scalable and practical technologies for digital PCR implementation. Serial dilution is laborious and introduces the possiblity of pipetting error competing chip based systems rely on complex fluidics schemes for partitioning. Droplet Digital PCR addresses these shortcomings by massively partitioning the sample in the fluid phase in one step. The creation of tens of thousands of droplets means that a single sample can generate tens of thousands of data points rather than a single result, bringing the power of statistical analysis inherent in digital PCR into practical application.

PCR technology enables high throughput digital PCR in a manner that uses lower sample and reagent volumes and reduces overall cost compared with other methods while maintaining the sensitivity and precision that are the hallmarks of digital PCR. The benefits of dd. PCR technology include Absolute quantification dd. PCR technology provides an absolute count of target DNA copies per input sample without the need for running standard curves, making this technique ideal for measurements of target DNA, viral load analysis, and microbial quantification. Unparalleled precision the massive sample partitioning afforded by dd. PCR enables the reliable measurement of small fold differences in target DNA sequence copy numbers among samples Increased signal to noise ratio high copy templates and background are diluted, effectively enriching template concentration in target positive partitions, allowing for the sensitive detection of rare targets and enabling a 1. Removal of PCR bias error rates are reduced by removing the amplification efficiency reliance of q. PCR, enabling the detection of small 1. Simplified quantification neither calibration standards nor a reference the Cq method is required for absolute quantification. Reduced consumable costs reaction volumes are in the pico to nanoliter ranges, reducing reagent use and the sample quantity required for each data point 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. Superior partitioning dd. PCR technology yields 2. Technical Services.
