    Abstract

    Protocol for a PCR from a colony

    Steps

    1.

    Dissolve one colony in 20µL of nuclease-free water and heat at 80°C for 10 minutes.

    2.

    Prepare the following 50 uL reaction in a 0.2mL PCR tube on ice:

    AB
    Magnesium chloride (MgCl2) 25 mM4 µL
    5X Colorless GoTaq Buffer5 µL
    PCR Nucleotide Mix 10 mM0.5 µL
    Forward primer 10 uM1 µL
    Reverse primer 10 uM1 µL
    GoTaq DNA polymerase (5u/uL)0.2 µL
    DNA Colony10 µL
    Nuclease-free water3.3 µL
    TOTAL25 µL
    3.

    Gently mix the reaction and spin down in the microcentrifuge

    4.
