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
