In the case of low amplification efficiency, the concentration of primers can be increased; When non-specific reactions occur, the primer concentration can be reduced to optimize the reaction system. 2. PCR reaction conditions Step Temperature Time / Pre denaturation 94℃ 2 min / Denaturation 94℃ 30 s 25-35 cycles Anneal 55-65℃ 30 s 25-35 cycles Extend 72℃ 30 s 25-35 cycles Finally extended 72℃ 2 min / Attention:1) In general experiments, if the annealing temperature is 5 ℃ lower than the melting temperature Tm of the amplification primer, and the ideal amplification efficiency cannot be achieved, the annealing temperature should be appropriately reduced; When non-specific reactions occur, increase the annealing temperature to optimize the reaction conditions.2) The extension time should be set according to the size of the amplified fragment. The amplification efficiency of Es Taq DNA Polymerase in this product is 2 kb/min.3) The number of cycles can be set based on the downstream application of the amplification product. If the number of cycles is too small, the amplification amount is insufficient; If there are too many cycles, the probability of mismatches will increase, and non-specific backgrounds will be severe. So, while ensuring product yield, the number of cycles should be minimized as much as possible...
