Standard polymerase chain reaction (PCR) protocol.
For a 50 μL PCR reaction:
- 35 μL H2O
- 5 μL 10X PCR buffer
- 5 μL 2mM dNTPs (each)
- 1.5 μL 50mM MgCl2
- 1 μL 50μM sense primer
- 1 μL 50μM antisense primer
- 1 μL 5nM DNA template
- 0.5 μL TAQ DNA polyermerase
- In a PCR tube, mix the components on ice in the order they are listed above.
- Perform the following thermocycling program:
- 95 °C 5 min (initial melting)
- 95 °C 30 s (melting)
- TH 30 s (annealing)
- 72 °C 1 min for each 1 kb PCR product (elongation)
- Repeat steps 2-4 a total of 12-36 times (24 is standard).
- 72 °C 5 min (final elongation)
- 12 °C hold (storage)
- Clean PCR product with PCR Purification Kit.
