  2. Reverse transcription polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcription...

    In this article, RT-PCR will denote Reverse Transcription PCR. Combined RT-PCR and qPCR are routinely used for analysis of gene expression and quantification of viral RNA in research and clinical settings. The close association between RT-PCR and qPCR has led to metonymic use of the term qPCR to mean RT-PCR.

  3. Real-time polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Real-time_polymerase_chain...

    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 ...

  4. Variants of PCR - Wikipedia

    en.wikipedia.org/wiki/Variants_of_PCR

    RT-PCR is widely used in expression profiling, which detects the expression of a gene. It can also be used to obtain sequence of an RNA transcript, which may aid the determination of the transcription start and termination sites (by RACE-PCR ) and facilitate mapping of the location of exons and introns in a gene sequence.

  5. Digital polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Digital_polymerase_chain...

    Real-time Digital PCR (rdPCR) combines the methodologies of digital PCR (dPCR) and quantitative PCR (qPCR), integrating the precision of dPCR with the real-time analysis capabilities of qPCR. This integration aims to provide enhanced sensitivity, specificity, and the ability for absolute quantification of nucleic acid sequences, contributing to ...

  6. Transcriptomics technologies - Wikipedia

    en.wikipedia.org/wiki/Transcriptomics_technologies

    Amounts of individual transcripts were quantified using Northern blotting, nylon membrane arrays, and later reverse transcriptase quantitative PCR (RT-qPCR) methods, [17] [18] but these methods are laborious and can only capture a tiny subsection of a transcriptome. [12]

  7. Detection of genetically modified organisms - Wikipedia

    en.wikipedia.org/wiki/Detection_of_genetically...

    Quantitative PCR (Q-PCR) is used to measure the quantity of a PCR product (preferably real-time, QRT-PCR). [2] It is the method of choice to quantitatively measure amounts of transgene DNA in a food or feed sample. Q-PCR is commonly used to determine whether a DNA sequence is present in a sample and the number of its copies in the sample.

  9. Polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Polymerase_chain_reaction

    A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.
