Procedure

PCR mix

• 9 μL PCR SuperMix High Fidelity
• 6.25 pmoles VF2 primer
• 6.25 pmoles VR primer
• 1 μL colony suspension
  • dilute 1 colony in 100 μL water

PCR conditions

1. 95°C for 15 minutes
2. 94°C for 30 seconds
3. 62°C for 30 seconds
4. 68°C for 3.5 minutes
5. Repeat 2-4 39 times.
6. 68°C for 20 mins
7. 4°C forever

Agarose gel electrophoresis

1. Dilute the reactions four-fold with water.
2. Perform an agarose gel electrophoresis of 20 μL of each diluted reaction using a 0.8% E-Gel®.
3. Also electrophorese 1 μg of 2-log DNA ladder to verify the length of each PCR product.
4. Image gel with 302 nm transilluminating ultraviolet light using an ethidium bromide camera filter and an exposure time of 614 milliseconds.
