WebA self dimer and cross dimer potential is shown for the best primer option. Multiplex qPCR will give the best results if all primers in the reaction have similar melting temperatures (Tm difference ≤ 2 °C) and do not form strong 3’-duplexes (ΔG ≥ –2.0 kcal). Optimizing Primer Concentrations and Annealing Temperature (T a) A primer dimer (PD) is a potential by-product in the polymerase chain reaction (PCR), a common biotechnological method. As its name implies, a PD consists of two primer molecules that have attached (hybridized) to each other because of strings of complementary bases in the primers. As a result, the DNA polymerase amplifies the PD, leading to competition for PCR reagents, thus potentially inhibiting amplification of the DNA sequence targeted for PCR amplification. In quantita…
