If the DNA input is fewer than 10 copies, up to 40 cycles may be required to produce a sufficient yield. More than 45 cycles is not recommended as nonspecific bands start to appear with higher numbers of cycles.
Splet27. mar. 2024 · In order for a virus like the COVID-19 virus to be detected early in the body using real time RT–PCR, scientists need to convert the RNA to DNA. This is a process called ‘reverse transcription’. They do this because only DNA can be copied — or amplified — which is a key part of the real time RT–PCR process for detecting viruses.
