It is primarily used to measure the amount of a specific RNA. This is achieved by monitoring the amplification reaction using fluorescence, a technique called real-time PCR or quantitative PCR (qPCR). Confusion can arise because some authors use the acronym RT-PCR to denote real-time PCR. In this article, RT-PCR will denote Reverse ...
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. Real-time PCR can be used ...
It also acted as a précis for the broader form of the guidelines. [5] Other researchers have been creating further versions for specific forms of qPCR that may require a supplementary or different set of items to check, including single-cell qPCR [ 6 ] and digital PCR (dPCR). [ 7 ]
The RT-LAMP technique is being supported as a cheaper and easier alternative to RT-PCR for the early diagnostics of people that are infectious for COVID-19. [6] There are open access test designs (including the recombinant proteins ) which makes it legally possible for anyone to produce a test.

Rapid amplification of cDNA ends (RACE) is a technique used in molecular biology to obtain the full length sequence of an RNA transcript found within a cell. RACE results in the production of a cDNA copy of the RNA sequence of interest, produced through reverse transcription, followed by PCR amplification of the cDNA copies (see RT-PCR).
Variants of PCR represent a diverse array of techniques that have evolved from the basic polymerase chain reaction (PCR) method, each tailored to specific applications in molecular biology, such as genetic analysis, DNA sequencing, and disease diagnosis, by modifying factors like primer design, temperature conditions, and enzyme usage.
The three core RPA enzymes can be supplemented by further enzymes to provide extra functionality. Addition of exonuclease III allows the use of an exo probe for real-time, fluorescence detection akin to real-time PCR. [1] Addition of endonuclease IV means that an nfo probe can be used for lateral flow strip detection of successful amplification.
