Revised Protocol: How To Extract DNA From Anything Living



I just found this page on easy DNA extraction and precipitation this morning, and although it closely mirrors classic ways to extract DNA from onions or strawberries, I was impressed by the addition of meat tenderizer or contact lens solution as a source of peptidase.  I was also struck by the suggestion to use either rubbing alcohol (easy to come by) or denatured ethanol (harder to come by).  Along those lines, I found this interesting page on whether to use isopropanol (IPA) or ethanol for DNA precipitation.  Although DNA is less soluble in IPA and will therefore precipitate more easily than from ethanol, so will the salt, so I suppose it depends on whether you want to use the DNA afterwards.
