[Abstract] This is a simple protocol for isolating genomic DNA from fresh plant tissues. DNA from this experiment can be used for all kinds of genetics studies, including genotyping and mapping. This protocol uses Edward’s extraction buffer to isolate DNA.

Materials and Reagents

  1. Ethanol (EtOH)
  2. Isopropanol
  3. NaCl
  4. EDTA
  5. SDS
  6. Tris (pH 7.5)
  7. Edward buffer (see Recipes)

Equipment

  1. Ceramic mortar and pestles
  2. Centrifuges (Eppendorf)
  3. Vortex (VWR International)

Procedure

  1. Add 400 μl Edward extraction buffer to a 1.5 μl tube.
  2. Take 2-3 small leaves or 1 big leaf, grind with pestle (2-3 weeks old).
  3. Vortex 5 sec, set at room temperature until all preps are ready.
  4. Spin at 16,000 rpm for 2 min.
  5. Transfer 300 μl of suspension to a fresh tube.
  6. Add 300 μl of isopropanol at room temperature for 2 min.
  7. Spin 5 min, wash pellet with 70% EtOH, and dry at room temperature.
  8. Resuspend in 100 μl H2O and store at -20 °C.
  9. Use 2 - 4 μl for PCR reaction to validate the presence of target DNA.

Recipes

  1. Edward buffer
    200 mM Tris (pH 7.5)
    250 mM NaCl
    25 mM EDTA
    0.5% SDS

Should it not be ul instead of ml throughout the procedures?

Yes, you are right. It should be ul, instead of ml. Guess it's a typo by the editorial team. sorry for that.

Can this method could be used for extraction of Medicago or red clover ?
