RESUMO
A fast, very simple and efficient method of DNA extraction is described which takes advantage of DNA sedimentation induced by millimolar concentrations of ZnCl2. The zinc-induced sedimentation is furthermore strongly promoted by submillimolar phosphate anion concentrations. Within <30 min, the method recovers >90% of DNA irrespective of whether a plasmid DNA or short oligonucleotides are the extracted material. The method works with plasmid DNA and oligonucleotide concentrations as low as 100 ng/ml and 10 microg/ml, respectively, without using any expensive facilities or toxic chemicals.
