What is Real-Time PCR (qPCR)? Bio-Rad

WebQuantitative PCR (Q-PCR) was used to measure the amount of PCR product. It is the preferred method to measure quantitatively the levels of transgenic DNA. Q-PCR is often … WebWhat does CT mean? In a real time PCR assay a positive reaction is detected by accumulation of a fluorescent signal. The CT (cycle threshold) is defined as the number of cycles required for the fluorescent signal to exceed background levels. CT levels are inversely proportional to the amount of target nucleic acid in the sample
