WebJan 11, 2024 · “The Ct value is often known as the ‘threshold cycle’ or ‘cycle threshold’, is the measurable number of PCR cycles from where the fluorescence signal crosses the base (threshold) line. Let’s first understand a bit about the fluorescence chemistry of qPCR. WebRT-PCR is used to detect the presence of a specific DNA sequence in a sample. The process begins with the reverse transcription of RNA into cDNA (complementary DNA). The cDNA is then amplified using PCR. The …
