| 摘要 |
This invention relates to a method of incorporating an exo-sample nucleotide into the amplified product strands resulting from a nucleic acid amplification process. Once the product strands have been obtained and analyzed (e.g., by hybridization, Southern blot, etc.), the exo-sample strands can be selectively destroyed by acting on the incorporated exosample nucleotide. Two embodiments are presented. ID a first embodiment, the exosample nucleotide is incorporated by carrying out the amplification reaction in the presence of an excess of exo-sample nucleotide triphosphate. In a second embodiment, the exo-sample nucleotide is incorporated by carrying out the amplification reaction in the presence of an oligonucleotide which has, as part of its sequence, one or more exosample nucleotides.
