PCR Verification of Successful GGA

If you want to use PCR to verify that GGA has happened, you can amplify the plasmid DNA inside the cells you grew overnight. After PCR, you will need to analyze the PCR product (often called an amplicon) by gel electrophoresis (2.0% agarose gel).

  1. For each PCR you want to perform on your eXperimental cells (e.g. X1, X2, X3), remove 2 µL of cells from the overnight culture. This will serve as your template.
  2. Use 2 µL of negative control (N) cells as template to see the MW of the PCR product when no GGA has occurred.
  3. Add the 2 µL of cell cultures to the labeled tubes for your particular receiving plasmid.
  4. The tubes already contain the paired PCR primers (see list below) and the green GoTaq master mix that includes buffer, dNTPs and Taq DNA polymerase. The volume of this tube is currently 23 µL and will be 25 µL after you add the template cells.
  5. Put your labeled tubes (treatment and group name) into the thermocycler. Your tubes will be incubated as follows:

  1. 95° C for 5 minutes, 1 time
  2. 95° C for 30 seconds
  3. 54° C for 30 seconds
  4. 72° C for 1 minute
  5. return to step #2 29 more times
  6. store at 22° C indefinitely
  • When the PCR is completed, they will be stored until next week when you will load 20 µL of each into the wells of a 2% agarose gel.
