    Digital PCR (dPCR) provides precise and absolute quantification of nucleic acids without a standard curve and without dependence on amplification efficiency. It is ultrasensitive; therefore, appropriate for testing allelic variants and targets of low abundance that are below the sensitivity limit of QPCR. It is also very precise, and is a better tool than QPCR when precise determination of the ratio of several nucleic acid sequences is required.

    Digital PCR Services
     
Avance Biosciences offers digital PCR services using Bio-Rad’s state-of-the-art Q200 digital droplet PCR system to support clients around the world.  We are specialized in assay development, validation, and sample testing to support GLP and cGMP submissions.

By employing multiple wells per sample, millions of droplets can be analyzed. Samples are partitioned into ‘droplets’ then large quantities (~20,000 of these partitioned droplets are analyzed using microfluidics technology to provide incomparable precision). Only the positive fraction of the sample is detected; therefore, dPCR can detect mutant alleles in circulating tumor DNA, event as few as 0.01% of cells such as L1 insertions, low-level pathogens, and relative expression in single cells.
