PCR Setup—Six Critical Components to Consider

WebTwo primers are used in each PCR reaction, and they are designed so that they flank the target region (region that should be copied). That is, they are given sequences that will make them bind to opposite strands of the template DNA, just at the edges of the region to be … Primers can be made that bind at the extension temperature (72°C), but … Web21 apr. 2024 · The concentration of each primer should be between 0.1 and 0.5 µM. For most applications 0.2 µM produces satisfactory results. Too high primer concentrations increase the chance of mispriming, which results in nonspecific PCR products. Limiting primer concentrations result in extremely inefficient PCR reactions.
