Abstract
Nucleic acids can be made available for amplification or other treatment after lysis by contacting the lysate with polyethyleneimine to form a precipitate with the nucleic acids. The nucleic acids are then released from the precipitate by contact with a strong base, and the released nucleic acids are kept in solution with an anionic phosphate ester surfactant. This method for preparing specimen samples is simple and quite rapid.
