RT-PCR. Reverse transcription polymerase chain reaction ( RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR). [1] It is primarily used to measure the amount of a specific RNA.
Quantitative Real-Time PCR ( QRT-PCR ), sometimes simply called Real-Time PCR ( RT-PCR ), refers to a collection of methods that use fluorescent dyes, such as Sybr Green, or fluorophore -containing DNA probes, such as TaqMan, to measure the amount of amplified product in real time as the amplification progresses.
A real-time polymerase chain reaction ( real-time PCR, or qPCR when used quantitatively) is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). It monitors the amplification of a targeted DNA molecule during the PCR (i.e., in real time), not at its end, as in conventional PCR.
Recombinase polymerase amplification (RPA) is a single tube, isothermal alternative to the polymerase chain reaction (PCR). [1] By adding a reverse transcriptase enzyme to an RPA reaction it can detect RNA as well as DNA, without the need for a separate step to produce cDNA ,. [2] [3] [4] Because it is isothermal, RPA can use much simpler ...
Transcription-mediated amplification. Transcription-mediated amplification ( TMA) is an isothermal (performed at constant temperature), single-tube nucleic acid amplification system utilizing two enzymes, RNA polymerase and reverse transcriptase . "Amplification" means creating many more copies of a strand of nucleic acid than was present at ...
Schematics of RT-LAMP amplification, exemplified for SARS-CoV-2 detection. Reverse transcription loop-mediated isothermal amplification ( RT-LAMP) is a one step nucleic acid amplification method to multiply specific sequences of RNA. It is used to diagnose infectious disease caused by RNA viruses.
Reverse transcriptase. Crystallographic structure of HIV -1 reverse transcriptase where the two subunits p51 and p66 are colored and the active sites of polymerase and nuclease are highlighted. [1] A reverse transcriptase ( RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.
RACE can provide the sequence of an RNA transcript from a small known sequence within the transcript to the 5' end (5' RACE-PCR) or 3' end (3' RACE-PCR) of the RNA. This technique is sometimes called one-sided PCR or anchored PCR. The first step in RACE is to use reverse transcription to produce a cDNA copy of a region of the RNA transcript. In ...
