Higher accuracy, sensitivity, and absolute quantification

Digital PCR (dPCR) is quickly becoming the go-to, complementary technology to real-time PCR for precise nucleic acid quantitation as it can deliver a high level of sensitivity and robust performance in the face of inhibitors. Digital PCR is being leveraged in a variety of research applications, providing unparalleled confidence in rare target quantification, copy-number-variation (CNV), gene expression, and more.

Digital PCR works by compartmentalizing a bulk PCR reaction into thousands of nanoliter-scale reactions, each containing zero, one, or just a few DNA molecules. By counting positive reactions and applying Poisson statistics, absolute quantification of the sample is achieved. dPCR overcomes common limitations of qPCR, such as the need for standard curves, low accuracy when measuring rare targets, and lack of sensitivity in high background conditions.

Powerfully simple digital PCR technology

The Applied Biosystems QuantStudio Absolute Q Digital PCR System offers a powerful yet easy-to-use digital PCR experience through its unique Microfluidic Array Plate (MAP) technology. This proprietary technology enables consistent and automated compartmentalization of a sample into 20,000 microchambers with best-in-class <1% coefficient of variation (CV). Unlike other digital PCR systems, MAP technology does not use emulsion or other droplet-based methods to compartmentalize reactions. Rather, utilizing distribution channels, the reagent is delivered to the microchambers with great precision and consistency. Additionally, the QuantStudio Absolute Q system analyzes more than 95% of the loaded sample, ensuring highly-accurate digital PCR results.
