Reverse transcription polymerase chain reaction - Wikipedia
网页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.

A beginner’s guide to RT-PCR, qPCR and RT-qPCR
网页2020年6月15日 · The conversion of RT-PCR testing to real-time RT-PCR or RT-qPCR allows high-throughput screening of patients, which is critical during a public health emergency. These tests have been rapidly designed following the deposition of the SARS-CoV-2 genome allowing prompt design of primers and probes specific for Covid-19.
What is Real-Time PCR (qPCR)? - Bio-Rad
网页What Is Real-Time PCR? In conventional PCR, the amplified DNA product, or amplicon, is detected in an end-point analysis. In real-time PCR, the accumulation of amplification product is measured as the reaction progresses, in real time, with product quantification after each cycle. The qPCR workflow below delineates the steps in real-time PCR.
Reverse Transcription Polymerase Chain Reaction - an overview ...
网页2021年8月27日 · Reverse transcriptase polymerase chain reaction (RT-PCR) is that technology by which RNA molecules are converted into their complementary DNA (cDNA) sequences by any one of several reverse transcriptases (RTs), followed by the amplification of the newly synthesized cDNA by standard PCR amplification. From: RNA Methodologies (Third Edition), 2005.
Reverse Transcription Polymerase Chain Reaction
网页Reverse transcription-polymerase chain reaction (RT-PCR) is a sensitive in vitro method and has a crucial role in medical science and biomaterial fields. RT-PCR is used for detecting and comparing the levels of mRNA and the surface proteins (Leong et al., 2007; Wang and Brown, 1999). PCR can be performed in real-time PCR and end-point PCR.
Reverse transcriptase (RT)-PCR: Principles, Applications
网页Reverse Transcriptase PCR (RT-PCR) is a variation of the polymerase chain reaction that amplifies target RNA. Addition of reverse transcriptase (RT) enzyme prior to PCR makes it possible to amplify and detect RNA targets. Reverse transcriptase enzyme transcribes the template RNA and forms complementary DNA (cDNA).
