Materials

  • Prepare master mix: (Total volume 50 µL)
    • 5X Rxn Buffer 10 µL
    • Oligo 1 (5µM) 7.5 µL
    • Oligo 2 (5µM) 7.5 µL
    • dNTP mix 1 µL
    • DMSO 1 µL
    • ddH2O 22 µL
    • Phusion 0.5 µL
  • NOTE: you will need 10µl of the master mix per colony, plus for positive and negative controls. Adjust volumes appropriately.
  • Oligos 1 and 2 are the primers for the BioBrick part, VF2 and VR. Make sure to dilute the concentration to 5 µM to prepare the appropriate amounts.


To prepare the cells

  • If you have a liquid culture:
  • Prepare as many PCR tubes as you have cultures you want to amplify. Add 100 µL of ddH2O to each of those PCR tubes.
  • Take 3 µL from each culture you want to PCR amplify and add to the PCR tubes (make sure to properly label each tube).
  • If you have plated colonies:
  • Prepare a sterile environment (wipe down counter with ethanol, get out a bunsen burner and light with a striker).
  • Sterilize metal innoculating loop with bunsen burner and scoop up one colony and mix into the appropriate PCR tube.

Procedure

  • Prepare connected PCR tubes (one for each colony, one for positive control, and one for negative control)
  • Add 10 µL master mix into each tube
  • Immediately cap the negative control to prevent cross-contamination.
  • Add 1 µL of diluted cell culture to its corresponding PCR tube (make sure to label everything)
  • Use a positive control that you know will work and has a known part
  • Close all caps and place in PCR Machine
  • Run PCR program COLONPCR_Protocol
  • Once this is complete, you will be able to analyze these colonies using gel electrophoresis and determine which colonies have the appropriate parts.
