Two-temperature pcr
WebThe position and orientation of the primers in a PCR reaction allow copy numbers to build up exponentially. The innovation with PCR is in having two primers flanking the target sequence. If you were to set up a reaction with one primer, you could make one DNA copy at a time. But with two primers, copy numbers grow exponentially with each cycle. WebAlways use the default 50 mM salt concentration in the calculation. For primers ≤20 nt, use the lower T m given by the calculator for annealing. For primers >20 nt, use an annealing …
