For the better understanding of the three terms I have tabulated in the following manner -
RT - PCR
RT -qPCR
Q-PCR
1) Reverse transcription polymerase chain reaction is a laboratory technique combining reverse transcription of RNA into DNA and amplification of specific DNA targets using polymerase chain reaction.
2) It is primarily used to measure the amount of a specific RNA.
1) Commonly, in RT-qPCR, RNA transcripts are quantified by reverse transcribing them into cDNA first, as described above and then qPCR is subsequently carried out.
2) As in standard PCR, DNA is amplified by 3 repeating steps: denaturation, annealing and elongation.
1) Q-PCR or Quantitative PCR is a method by which the amount of the PCR product can be determined, in real-time, and is very useful for investigating gene expression
