Splet21. okt. 2013 · Design your PCR primers according to the following guidelines suggested by IDT scientists: Melting temperature (Tm): The optimal melting temperature of the primers is 60–64°C, with an ideal temperature of 62°C, which is based on typical cycling and reaction conditions and the optimum temperature for PCR enzyme function. Splet24. mar. 2024 · Primer length. The optimal length of a PCR primer lies between 18 and 24 bp. Longer primers are less efficient during the annealing step, resulting in a lower amount of PCR product. Conversely, shorter primers are less specific during the annealing phase, leading to more non-specific binding and amplification. However, there are exceptions to ...
SpletLogically, longer extension times can increase the yield of longer PCR products because fewer partial products are synthesized. Extension times depend on the length of the target; times of 10–20 minutes are common. In addition, template quality is crucial.
