  2. Polymerase chain reaction optimization - Wikipedia

    en.wikipedia.org/wiki/Polymerase_chain_reaction...

    Secondary structures in the DNA can result in folding or knotting of DNA template or primers, leading to decreased product yield or failure of the reaction. Hairpins, which consist of internal folds caused by base-pairing between nucleotides in inverted repeats within single-stranded DNA, are common secondary structures and may result in failed PCRs.

  3. Digital polymerase chain reaction - Wikipedia

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

    Chip-based Digital PCR (dPCR) is also a method of dPCR in which the reaction mix (also when used in qPCR) is divided into ~10,000 to ~45,000 partitions on a chip, then amplified using an endpoint PCR thermocycling machine, and is read using a high-powered camera reader with fluorescence filter (HEX, FAM, Cy5, Cy5.5 and Texas Red) for all ...

    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.

  5. Helicase-dependent amplification - Wikipedia

    en.wikipedia.org/wiki/Helicase-dependent...

    The polymerase chain reaction is the most widely used method for in vitro DNA amplification for purposes of molecular biology and biomedical research. [1] This process involves the separation of the double-stranded DNA in high heat into single strands (the denaturation step, typically achieved at 95–97 °C), annealing of the primers to the single stranded DNA (the annealing step) and copying ...

  6. Nested polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Nested_polymerase_chain...

    Polymerase chain reaction itself is the process used to amplify DNA samples, via a temperature-mediated DNA polymerase.The products can be used for sequencing or analysis, and this process is a key part of many genetics research laboratories, along with uses in DNA fingerprinting for forensics and other human genetic cases.

  7. 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.

    Housing is too expensive, if there are options even available. Here's a breakdown of what's going on.

  9. Touchdown polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Touchdown_polymerase_chain...

    Scheme of touchdown PCR. The first annealing between primer and DNA occurs at the initial temperature, the second after the temperature has been lowered by Δ T {\displaystyle \Delta T} . Therefore, the product of the second annealing is disadvantaged by 2 − 1 {\displaystyle 2^{-1}} .
