WebbPCR cycle number determination. PCR steps of denaturation, annealing, and extension are repeated (or “cycled”) many times to amplify the target DNA. The number of cycles is usually carried out 25–35 times but may vary upon the amount of DNA input and the desired yield of PCR product. If the DNA input is fewer than 10 copies, up to 40 ...

Most PCR methods amplify DNA fragments of between 0.1 and 10 kilo base pairs (kbp) in length, although some techniques allow for amplification of fragments up to 40 kbp. The amount of amplified product is determined by the available substrates in the reaction, which becomes limiting as the reaction progresses.
