Two-step RT-PCR, as the name implies, occurs in two steps. First the reverse transcription and then the PCR. This method is more sensitive than the one-step method. Kits are also useful for two-step RT-PCR. Just as for one-step PCR, use only intact, high-quality RNA for the best results. The primer for two-step PCR does not have to be sequence ...
Following the extension of the OE-PCR reaction, the PCR mix or the eluted fragments of appropriate size are subject to normal PCR, using the outermost primers used in the initial, mutagenic PCR reactions. In addition, the combination of OE-PCR and asymmetric PCR could be used to improved the efficiency of site-directed mutagenesis. [2]
RT-PCR (or Reverse Transcription PCR) is used to reverse-transcribe and amplify RNA to cDNA. PCR is preceded by a reaction using reverse transcriptase, an enzyme that converts RNA into cDNA. The two reactions may be combined in a tube, with the initial heating step of PCR being used to inactivate the transcriptase. [4]
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.
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 ...
There are three components that are critical to the KASP assay: 1) a purified DNA sample, 2) two allele-specific forward primers, and 3) a common reverse primer. A minimum of 5-10 ng of the extracted DNA sample is required for the method to function properly. The DNA sample is purified by adding a mixture of chemicals to the buffer solution. [2]

RC-PCR provides significant advantages over other methods of amplicon library preparation methods. Most significantly it is a single closed tube reaction, this eliminates cross contamination associated with other two-step PCR approaches as well as utilising less reagent and requiring less labour to perform.
