==Tips==
*50μL volume total volume
*1 ng template DNA and [300nM] of each primer (~200ng)
*Run at 55c regardless of melt temps from primer design programs
**2nd pass: run a temp gradient trial from 48-64c
**3rd pass: run PCR reaction with betane for low GC sequences
*Do a pcr clean up (elute with 30μL) and run a gel
==Controls==
*Digest a control fragment of similar length and also run on gel
==Steps==
#Dilute plasmid/template DNA to a concentration of 1ng/μL, and label this tube 'XXXX for PCR'
#*Dilution review: If start with 50ng/μL plasmid DNA, add to a tube 49μL of water and 1μL of the 50ng/μL plasmid DNA.
#Prepare 25μM tubes of each primer (if you don't have them already)
#Add in order: (50μL in little pcr-sized tube)
#*49μL of Tom's PCR mix
#*1μL template DNA (=1 ng template DNA)
#*.6μL of each primer (forward and reverse) (.6 μL of the 25μM primer yields roughly [300 nM])
#Run the tubes on the thermocycler at an appropriately designed program:
#*~95deg for 3:00
#*30 cycles of (a) melt (b) anneal (c) extend
#*~72deg for 10:00
