Protocols

DNA precipitation with sodium acetate

(estimated time: 1 hour)

  • Add 1/10 DNA solution volume of sodium acetate 3 M
  • Add 2.5 DNA solution volume of absolute ethanol
  • Freeze at -80°C for 30 min
  • Centrifuge at 13000 rpm, 4°C for 20 min
  • Decant supernatant
  • Add 50 µl of 70% ethanol
  • Centrifuge at 13000 rpm, 4°C for 20 min
  • Remove all supernatant with a pipette
  • Air dry pellet until ethanol is totally removed
  • Elute with 5-10 µl of ddH2O
