Web1 Introduction. Although standard reverse transcriptase-polymerase chain reaction (RT-PCR) is a remarkably sensitive technique, its sensitivity can be further increased by performing “nested” RT-PCR. This involves taking an aliquot of the product from the primary RT-PCR, and using it as a template for a secondary round of PCR amplification.

To amplify a segment of DNA using PCR, the sample is first heated so the DNA denatures, or separates into two pieces of single-stranded DNA. Next, an enzyme called "Taq polymerase" synthesizes - builds - two new strands of DNA, using the original strands as templates.
WebFor efficient priming, the design tool avoids primers with extensive self-dimer and cross dimer formations in order to minimize primer secondary structure and primer dimer formation. Click on the "Design Primers" button to get a list of appropriate PCR primer pairs. The output includes a proposed annealing temperature for each listed primer pair.
