Jun 24, 2016 · (endpoint semi-quantitative PCR) or while the amplification is still progressing (real-time QPCR) In endpoint semi-quantitative PCR, fluorescence data are collected after the amplification reaction has been completed, usually after 30–40 cycles, and this final fluorescence is used to back-calculate the amount of template present prior to PCR

What is quantitative PCR?
Quantitative PCR (formally quantitative real-time PCR, qPCR) detection builds on the basic PCR technique and allows researchers to estimate the quantity of starting material in a sample.
What is the difference between qPCR and conventional PCR?
Since the products are detected as the reaction proceeds, qPCR has a much wider dynamic range of analysis than conventional, end-point PCR; from a single copy to around 1011copies are detectable within a single run.
What is the starting point of a real-time quantitative PCR assay?
Whatever the platform or chemistry involved, the starting point of a real-time assay is a tissue-specific RNA and the end point of a real-time reaction is an amplification plot.
