Method for treating nucleic acid that is to be amplified such that the nucleic acid is, after amplification, subsequently unamplifiable. Nucleic acid amplification is performed in a reaction containing means in the presence of an isopsoralen. The reaction is thereafter irradiated to render the amplified nucleic acid substantially unamplifiable.
