Evaluation of microfluidic digital PCR for the detection of cancer biomarkers
Published: September 30, 2009
dPCR is achieved by sample partitioning prior to PCR amplification such that each reaction chamber contains one copy or less of target DNA. This dilution becomes the limiting factor and an accurate target molecule count is achievable. This study evaluates dPCR’s quantitative capabilities and investigates parameters influencing copy number quantification, using the Fluidigm Biomark instrument. Biomark technology combines dPCR theory with a microfluidics platform.
