    Abstract

    This is the common Polymerase Chain Reaction (PCR) protocol followed by the 2023 NUS-Singapore iGEM team.

    Before start

    Steps

    1.

    Prepare a PCR tube.

    2.

    Thaw the KOD OneTM PCR Master Mix (Blue) from the -20°C fridge.

    3.

    For a 50μL PCR sample, add the following into a PCR tube (follow the sequence):

    AB
    KOD OneTM PCR Master Mix (Blue)25μL
    Each Primer (2 primers in total)1.5μL
    DNA Template1μL
    DI Water21μL
    4.

    Vortex the PCR tubes to mix well.

    5.

    Place the PCR tube into the Thermal Cycler with the following conditions:

    **Lid Temperature: 105°C; Volume: 50μL

    ABC
    98°C10s
    68°C5sEdit: -1°C per cycle
    68°C1 minute
    Go to step 1, repeat the cycle 13 times
    98°C10s
    55°C5s
    68°C1 minute
    Go to step 5, repeat the cycle 25 times
    68°C5 minutes
    12°CInfinite Loop (∞)
    6.

    Upon finishing, cancel the current protocol and take out the PCR sample from the Thermal Cycler. Keep the sample in the 4°C fridge for storage. Otherwise, gel electrophoresis may be carried out to isolate the DNA fragment of interest.
