Real-Time PCR (qPCR), endpoint PCR, and dPCR – how to choose, when to combine, and why it matters for modern molecular research
PCR isn’t one-size-fits-all. This guide breaks down the distinct roles of real-time PCR (qPCR), endpoint PCR, and digital PCR (dPCR)—and shows how they complement each other in gene expression analysis and related workflows, from early screening to quantitative and absolute measurements.
This guide walks through:
- qPCR basics: How real-time fluorescence tracking enables fast, reproducible quantification across a wide dynamic range
- Endpoint PCR: Fundamentals and where the technique shines for qualitative detection
- dPCR explained: How
partitioning into thousands of micro-reactions enables absolute quantification
without standard curves, supporting low-abundance/rare targets and other
challenging analysis.
- Smarter PCR
method decisions: When to stay with qPCR versus when to transition to dPCR for higher
sensitivity or absolute quantification.
- Better inputs/better
results: How sample preparation quality (especially RNA purity/integrity and
reverse transcription performance) directly impacts downstream PCR
reliability—particularly for quantitative applications.
The
guide includes a clear method-transition framework tailored to gene expression analysis.
