The key equipment for qPCR is a specialized thermocycler with fluorescence detection modules which is used to monitor and record the fluorescence in real-time as amplification occurs A typical workflow of qPCR for gene expression measurement involves RNA isolation reverse transcription qPCR assay development qPCR experiment and data analysis
What is qPCR data analysis?
Gene expression analysis by real-time qPCR has been a key enabler of a routine and robust approach for measuring gene expression in genes of interest, as well as monitoring biomarkers. This section will provide the key features of qPCR data analysis and describe examples of common methods to analyze data from a qPCR assay.
What is the exponential phase of qPCR?
Important Parameters of Quantitative PCR (qPCR) Analysis Exponential Phase It is important to quantitate your qPCR at the early part of the exponential phase of amplification instead at the later cycles or at the plateau. At the beginning of the exponential phase, all reagents are still in excess.
How does a qPCR machine measure fluorescence?
The qPCR machine measures the intensity of fluorescence emitted by the probe at each cycle. During the first cycles, there is not enough fluorescence to be detected, but the reaction rapidly produces more and more amplicons and the fluorescence builds up. A qPCR curve has typically an exponential phase followed by a plateau phase.
What is a typical workflow of qPCR for gene expression measurement?
typical workflow of qPCR for gene expression measurement involves RNA isolation, reverse transcription, qPCR assay development, qPCR experiment and data analysis. Special attention is needed for preventing RNA degradation.
