WebSo the general formula to calculate the number is: n × 2 c y c l e s = number of DNA molecules at the end of the PCR n is the number of molecules set into the reaction So for our 600 DNA molecules with 25 cycles this would give: 600 × 2 25 = 20.132.659.200 or roughly 20.1 billion molecules of DNA. Share Improve this answer Follow WebTo calculate primer efficiency values, use the following equation. The formula to do this in Excel can be found below. = (10^ (-1/The Slope Value)-1)*100. This will give you a primer efficiency score as a percentage. Hopefully, this is between 90 – 110%. By using the above dataset, the efficiency comes to 98%.

PCR amplifies a specific region of a DNA strand (the DNA target). 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.
