Droplet Digital™ PCR (ddPCR™) is a breakthrough technology that provides ultrasensitive nucleic acid detection and absolute quantification. It is highly effective for resolving low abundance targets, such as allelic or structural variants, that are below the level of detection of other platforms. This technology is now approved for use in in vitro diagnostics.
With advanced multiplexing offerings, ddPCR technology maximizes the number of targets analyzed per well without sacrificing performance.
NEW PRODUCTQX600 Droplet Digital PCR System
Since its introduction, ddPCR technology has advanced critical fields of research through unmatched sensitivity, precision, and absolute quantitation. Now the QX600 System provides advanced, 6-color multiplexing to maximize the number of biomarkers interrogated per well, allowing the preservation of precious samples and reducing lab burden.

Droplet Digital PCR Technology
Based on water-emulsion droplet technology, Droplet Digital PCR fractionates a DNA sample in 20,000 droplets. PCR amplification of the template subsequently occurs in each individual droplet, and counting the positive droplets gives precise, absolute target quantification.
Read more about Droplet Digital PCR technology or learn how to transition your assay from qPCR to ddPCR.

-
DNA sample with target sequence is partitioned into droplets
-
Target and background DNA are randomly distributed among 20,000 droplets
-
Target sequence is amplified by end-point PCR in each droplet
-
Positive droplets are counted to give precise quantification of target sequences in sample
Benefits of Droplet Digital PCR
Absolute quantification — provides an absolute count of target DNA copies per input sample without the need for standard curves
Highest precision and sensitivity — enriched template concentration in target-positive droplets allows higher precision and sensitivity than real-time PCR
Removal of PCR efficiency bias — error rates are reduced by removing the reliance on amplification efficiency of qPCR
