Making Reverse pARA
From 2006.igem.org
PCR primers arrive Tuesday
- spin down tubes with dry DNA
- calculate volume dH2O to give 200 pmol/ul, label as "10X"
- dilute 10X to make 1X
Conduct PCR (30 cycles, use Tm to determine annealing temp)
- 1 ul Forward primer
- 1 ul Reverse primer
- 2 ul 10X with no Mg
- 2 ul 25 mM MgCl2
- 12 ul dH2O
- 1 ul Taq
- 1 ul plasmid with pARA (labeled I13453, in right freezer)
Add 5 ul 5X loading buffer and run on 7% PA gel (product should be 150 bp)
If this works, scale up the PCR to 5 x 20 ul, run new PA gel, and purify band. Elute in 2 x 40 ul.
Digest these two things in separate tubes with both XbaI and SpeI
- 150 bp pAra band from above
- plasmid I13522 (pTet-GFP, glows green with UV)
Design and set up ligations
- 20 ng pTet-GFP X/S only
- 20 ng pTet-GFP X/S + 10 ng pARA X/S
