The method or protocol includes: organelle isolation, deoxyribonuclease treatment, lysis, deproteinisation and a final DNA purification with sodium dodecyl sulphate and potassium acetate. The organelle DNA yield is 5–10 micrograms per gram of tissue and the DNA is fully restrictable. The technique is inexpensive and appropriate for the isolation of multiple samples of organelle DNA from a small amount of tissue.
