PCR

Briefly, a typical reaction is set up as follows:


1. set up pre-labeled reaction tubes on ice

2. add the following components:

- 2µL  PCR buffer (rock gently after thawing, quick spin before use)
- 1.2uL  Mgcl2
- 0.4uL  dNTPs
- 200nM final concentration of each primer 
- 0.2uL Taq enzyme
- template DNA

(note: the total volume of PCR is 20µL)

3. make sure reaction tubes are properly capped before placing in thermocycler

4. perform PCR with an initial heating step at 94C for 5 minutes followed by 25-35 cycles of 30sec at 94C, 30sec at 55C and 1Kb/min at 72C
