    摘要: The present invention provides nucleic acid molecules which may be used as standards for estimating the size (in base pairs) and mass of linear, double-stranded or single-stranded nucleic acid molecules separated by size. The nucleic acid molecules of the invention may be DNA molecules, RNA molecules or DNA/RNA hybrid molecules, and may be double-stranded or single-stranded. The invention also provides methods for producing nucleic acid sizing ladders from these nucleic acid molecules, ladders produced by such methods, and methods for estimating the size and mass of nucleic acid molecules by comparison to these nucleic acid sizing ladders.

    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 exo-sample nucleotide. Two embodiments are presented. In a first embodiment, the exo-sample 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 exo-sample nucleotides.

    摘要: In the process according to this invention, 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. 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.
