    摘要: A method of incorporating an exo-sample nucleotide (e.g. deoxyuridine in DNA) into amplified product strands resulting from a nucleic acid amplification process is disclosed. Once the product strands have been obtained and analysed (e.g. by hybridisation, Southern blot, etc.), the exo-sample strands can be selectively destroyed by acting on the incorporated exo-sample nucleotide.
    Two procedures are described. In the first procedure the exo-sample nucleotide is incorporated by conducting the amplification reaction in the presence of an excess of exo-sample nucleotide triphosphate.
    In the second procedure the exo-sample nucleotide is incorporated by conducting the amplification reaction in the presence of an oligonucleotide which has, as part of its sequence, one or more exo-sample nucleotides.

    摘要: A process for substantially amplifying template nucleic acid present in a sample is described, wherein the amplification may be performed without the need for prior knowledge of specific sequences. The process comprises apposition of random oligonucleotide primers to the template nucleic acid under conditions such that extension products of the primers are synthesised which are complementary to the template nucleic acid.

    摘要: An amplification procedure is performed on a first sample in which one or more of the four normal ribonucleoside triphosphates(rNTPs) or deoxyribonucleoside triphosphates (dNTPs) is replaced with an exo-sample nucleotide that is not present in nucleic acid to be amplified. After amplification, any contaminating amplified product that may be remaining is subjected to a physical, chemical, enzymatic, or biological treatment which renders nucleic acid containing the exo-sample nucleotide substantially unamplifiable. The treatment may be done as a separate step or it may be done in the presence of a second sample containing nucleic acid sequences to be amplified. The amplified nucleic acid sequences derived from the first sample which contaminate the second sample are not further substantially amplified during amplification of nucleic acid sequences of the second sample.
