Rapid isolation of high molecular weight plant DNA.
Nucleic Acids Research, 1980 A method is presented for the rapid isolation of high molecular weight plant DNA (50,000 base pairs or more in length) which is free of contaminants which interfere with complete digestion by restriction endonucleases. The procedure yields total cellular
