Purification of pSB1C3-pDawn

20 µL of ligation product + 80 µL of H₂O MQ
Add 1/10 (10 µL) of the volume of NaOAc 3M pH 5.2
Add 2,5 volumes (275 µL) of Ethanol 100%
Mix and stored at -20°C for 1 hour at least
Centrifuge 30 sec, 14000 rpm at 4°C
Discard the supernatant
Resuspend the pellet with 500 µL of ethanol 70%, invert up the tube several time
Centrifuge 5 min, 14000 rpm at 4°C
Discard the supernatant and let dry the pellet
Resuspend the pellet with the right amount of water following the final concentration expected (20 µL here)
