Digital PCR, or dPCR, is a technique that allows for the precise quantification of nucleic acids in a sample. Unlike traditional PCR which amplifies target DNA or RNA molecules exponentially, dPCR partitions the sample into thousands of individual reactions, each containing a single molecule or few molecules of the target nucleic acid. This digital partitioning allows for absolute quantification without the need for a standard curve, making dPCR more accurate and sensitive than traditional qPCR. dPCR has applications in various fields including genomics, molecular diagnostics, and environmental monitoring.
