Webtemperature is 3-5 degrees Celsius below the melting temperature. Too high of an annealing temperature prevents optimal binding of the primers to the templates while too low of an annealing temperature can lead to non-specific binding and, subsequently, non-specific PCR products. Extension occurs after the primers hybridize to the templates. WebAnnealing temperature too low. Primer Annealing temperature should be 5°C lower than the lowest primer melting temperature (Tm). The time of annealing is 30 sec. Too low annealing temperature leads to high background, too high one may lead to no product in qPCR.
