dPCR and qPCR are two major techniques employed in the quantification of nucleic acids, DNA, and RNA. Both provide very precise and sensitive measurements of the templates; however, they differ fundamentally in approach.
qPCR: A Real-Time Approach
The widely used technique of qPCR monitors, in real-time, the amplification of a target DNA sequence. It does so by measuring at each cycle the amount of fluorescence emitted during PCR, hence enabling quantification of the initial target DNA copy number.
dPCR: A Partition-Based Approach
In contrast, dPCR segregates a sample into several thousand independent reactions. Each partition represents an independent PCR reaction, and the presence or absence of the target sequence is determined in each partition at the end of the reaction. By counting the number of positive and negative partitions, the absolute number of target molecules originally present in the sample can be calculated.
