    • The invention provides a method for detecting and quantifying the amount of target molecules, such as nucleic acids or proteins in a sample. The target molecules are first recognized and bounded by target-specific probes, generally nucleic acids or proteins that bind specifically to the targets, each of which is labeled with a short single-stranded nucleic acid probe, either DNA or RNA, with distinct molecular weight. This label is called an oligonucleotide mass tag. One or several standard oligonucleotide sequences can be designed with similar sequence but distinct molecular weight to those oligonucleotide mass tags. Then the oligonucleotide mass tags associated with bounded probes and the standard sequences are co-amplified using a pair of common primers. The presence and/or amount of each oligonucleotide mass tag, which corresponds to the amount of corresponding target molecule, is determined by a primer extension reaction and quantification of the primer extension product.
    • 本发明提供了用于检测和定量样品中靶分子如核酸或蛋白质的量的方法。 目标分子首先被目标特异性探针识别并结合,通常是与靶标特异性结合的核酸或蛋白质,其中每一个都用不同分子量的短单链核酸探针(DNA或RNA)标记 。 该标签称为寡核苷酸质量标签。 可以设计一个或几个标准寡核苷酸序列,其具有与那些寡核苷酸质量标签相似的序列但分子量不同。 然后使用一对普通引物共同扩增与有界探针和标准序列相关的寡核苷酸质粒标签。 通过引物延伸反应和引物延伸产物的定量来确定对应于相应靶分子量的每个寡核苷酸质粒标签的存在和/或量。

    • The present invention relates to a method for measuring the amount of a target nucleic acid in a sample using a standard which is designed to have one base difference compared with the gene of interest or a "target nucleic acid sequence." Use of such standard in combination with a method of "enhancing" the difference in the standard and the test nucleic acid sample using, for example, a base extension reaction carried right at the mutation site allowing amplification of the standard and target nucleic acids with the same efficiency and facilitating quantification of the target nucleic acid. Thereafter a means of quantifying the "enhanced" standard and target nucleic acid samples is used to determine the amount of the target nucleic acid. In the preferred embodiment, the quantification means is Mass Spectrometry.
    • 本发明涉及使用设计为与目的基因相比具有一个碱基差的标准或“靶核酸序列”来测量样品中靶核酸量的方法。 使用这样的标准物与“增强”标准差异的方法和使用例如在突变位点上携带的碱基延伸反应的测试核酸样品的方法相结合,可以扩增标准品和靶核酸 相同的效率和促进目标核酸的定量。 此后,使用定量“增强”标准和靶核酸样品的手段来确定靶核酸的量。 在优选实施方案中,定量方法是质谱法。
