Colony PCR
Supplies needed:
- PCR tubes
- BioBrick PCR primers (VF2, VR)
- Taq polymerase
- 10x Reaction Buffer
- 10mM dNTPs
- dH2O
Colonies
Steps:
- Make master mix of PCR components except the DNA. Keep on ice. https://static.igem.org/mediawiki/2013/b/ba/PCR_A.JPG 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)
- Aliquot 25µL per PCR tube, keep tubes on ice. *Following steps must be done near the flame*
- Touch toothpick/ pipet tip/ loop tp colony, then index plates, then dip in the PCR tube. *Turn of flame*
- Run PCR:
- Turn machine on
- Load samples in machine
- Select appropriate temperatures and times
- 95°C for 10s
- 94°C for 30s
- 60°C for 30s
- 68°C for 1min per kb of expected product (round up)
- Repeat 2-4 30times
- 68°C for 20 mins
- 4°C forever
- Once finished, remove the PCR tubes from the machine.
- Verify PCR products agerose gel or store PCR tubes at 4°C or -20°C.
