Sensitivity Comparison of Digital PCR and Real-time PCR (qPCR)

In molecular biology research, the sensitivity of detection methods is crucial for accurately quantifying nucleic acids. When comparing the sensitivity of different techniques, two commonly used platforms are Digital PCR and Real-time PCR (qPCR). They have distinct approaches to quantification that impact their sensitivity. Digital PCR directly counts the number of target molecules by partitioning the sample into discrete reaction chambers, whereas Real-time PCR (qPCR) measures the amplification signal during the exponential phase.

The results demonstrated that Digital PCR and Real-time PCR (qPCR) exhibited comparable sensitivities for detecting low-abundance targets. Digital PCR had an advantage in accurately quantifying targets present at extremely low concentrations due to its ability to provide absolute quantification without relying on a standard curve. Both platforms offer high sensitivity for detecting low-abundance targets. Researchers should consider the specific requirements of their experiments and choose the appropriate platform accordingly.
