PCR using a GoTaq® polymerase


Amplify a specific section of DNA.


Following are the instructions from the Promega website.

  1. Set up the thermocycler at the right temperatures.

  2. In a 200 µL PCR tube, introduce :
    • 1.25 µL of forward primer (10µM)
    • 1.25 µL of reverse primer (10µM)
    • 2.5 µL of dNTP (2 mM)
    • 5 µL of GoTaq® Reaction Buffer
    • variable volume of template DNA
    • 0.12 µL of GoTaq® polymerase
    • to 25 µL of nuclease-free water

    Those products are not dangerous at first sight, but in case of spreading or contacts with any part of the body, it is recommended to wash this part and to dry it after. Use a different pipette tip for each sample. It is also important to close tubes after putting the different reagents. DNA is more sensitive to its environment while it is not circulared in a plasmid and introduced into a cell. Therefore, a spreading has very few chances to lead to any bad consequences.

  3. Put the 200 µL PCR tube into the thermocycler.

  4. Turn on the device.

    It was noticed that it exists a certain number of different thermocycler models. Each device has its own user guide which should be thoroughly read before using the device. The use of Thermocyclers can present risks. Indeed it is an electric device which can become very hot, and in case of misused, people can be injured.
