Droplet Digital PCR (ddPCR)

Droplet Digital PCR (ddPCR) is a precise laboratory technique used to measure tiny amounts of DNA. It works by dividing a sample into thousands of tiny droplets, each acting as a mini-test tube. This allows scientists to perform multiple reactions simultaneously. In each droplet, a specific DNA target can be detected and quantified if present. By counting the positive droplets after amplification, researchers can determine the exact number of DNA molecules in the original sample. ddPCR is particularly valuable in areas like cancer research and genetic testing, offering high sensitivity and accuracy in DNA analysis.
