DNA precipitation with sodium acetate
(estimated time: 1 hour)
Materials needed:
- sodium acetate

- previously cut plasmid
- Add 1/10 digestion volume of sodium acetate 3 M
- Add 2.5 digestion volume of absolute ethanol
- Freeze at -80°C for 30 min
- Centrifuge at 13000 rpm, 4°C for 20 min
- decant supernatant
- Add 50 l of 70% ethanol
- Centrifuge at 13000 rpm, 4°C for 20 min
