What are your melting temperatures? You can use the following equation to determine annealing temperature: Ta = average melting temperature of both forward and reverse primers then subtract 3 degrees from the total. However, its best to run a gradient PCR...

There is no "exact" annealing temperature of a pcr reaction. I would start the pcr with some degrees below the lower Tm-value (3 - 5 C). If there are non-spezific bands, rise the temperature stepwise (1 - 2 degree per step). Or, if possible, you can perfo...

Annealing Time An annealing time of 30-45 seconds is commonly used in PCR reactions. Increase in annealing time up o 2-3 minutes did not appreciably influence the outcome of the PCR reactions. However, as the polymerase has some reduced activity between ....

Primers, also known as "oligos," are short strands of nucleotides called oligonucleotides that are used as priming sequences in Polymerase Chain Reactions (PCR). The primers "base-pair" to the ends of the sequence you wish to copy, providing 3'-end attach...
