Basic Knowledge about DNA Extraction

... such as SDS is viable to remove lipid membranes. Besides, DNA associated with other cellular proteins can be degraded with the addition of a protease. What’s more, the precipitation of a protein can be achieved by adding salt such as ammonium or sodium acetate. When the sample is vortexed ...
