Digital Droplet PCR


Digital PCR is a breakthrough technology that provides ultrasensitive and absolute nucleic acid quantification. It is particularly useful for low abundance targets, targets in complex backgrounds, allelic variants (SNPs), and for monitoring subtle changes in target levels that cannot be detected with real-time PCR.

Droplet Digital PCR Technology


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.

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


High throughput-simple and easy-to-use workflow with 96-sample throughput does not require multiple dilution steps



Removal of PCR efficiency bias- error rates are reduced by removing the reliance on amplification efficiency of qPCR
