Colony PCR


Supplies needed:


  • PCR tubes
  • BioBrick PCR primers (VF2, VR)
  • Taq polymerase
  • 10x Reaction Buffer
  • 10mM dNTPs
  • dH2O

Steps:

  1. Make master mix of PCR components except the DNA. Keep on ice.


    2. N=number of samples
    *Add about extra amount worth two samples to account for water control and pipetting error. (if regular PCR is done use ca.50-200ng template DNA and use Phusion and 10x Phusion buffer instead of Taq)

  2. Aliquot 25µL per PCR tube, keep tubes on ice.
    3. *Following steps must be done near the flame*

  3. Touch toothpick/ pipet tip/ loop tp colony, then index plates, then dip in the PCR tube.
    4. *Turn of flame*

  4. Run PCR:
    1. Turn machine on
    2. Load samples in machine
    3. Select appropriate temperatures and times
      1. 95°C for 10s
      2. 94°C for 30s
      3. 60°C for 30s
      4. 68°C for 1min per kb of expected product (round up)
      5. Repeat 2-4 30times
      6. 68°C for 20 mins
      7. 4°C forever

    4. Once finished, remove the PCR tubes from the machine.
    5. Verify PCR products agerose gel or store PCR tubes at 4°C or -20°C.
