Nuclear DNA extraction from Algae
Total DNA isolation protocol
- Place 1.5 ml of algae culture into centrifuge tube.
- Spin down cells at 5000 rpm for 1 minute.
- Pipette off supernatant.
- Add 400 µl extraction buffer.
- Incubate for 15 minutes at 50ºC, inverting tubes several times during incubation.
- Centrifuge at 13000 rpm for 5 minutes.
- Transfer supernatant to new tube.
- Add 400 µl isopropanol.
- Invert several times.
- Place on ice for 5 minutes.
- Centrifuge at 13000 rpm for 10 minutes.
- Pour off supernatant and wash pellet with 500 µL of 70% ethanol, ensuring to resuspend the pellet.
- Centrifuge at 13000 rpm for 1 minutes.
- Decant ethanol and place tubes upside down on paper towel to dry off excess ethanol.
- Dissolve pellet in 50 µl elution buffer, place tube on bench for 4 hours.
- Centrifuge at 13000 rpm for 2 minutes.
- Discard the supernatant, DNA is in the pellet.
