    • The present invention provides a method for the detection of the presence of RNA variants comprising the step of performing a competitive cDNA synthesis comprising a first primer specific to a first RNA variant, a second primer specific to a second RNA variant, an RNA-dependent DNA polymerase, and RNA from said sample as a template, wherein said first primer and said second primer comprise an allele-specific nucleotide portion, a target-specific sequence and tag units with a common sequence and/or a discriminating sequence so that the sequence of said tag units is not complementary to said first or second RNA variant, wherein each of the cDNA products obtained from said competitive cDNA synthesis consists of the sequence of only one primer extended by the sequence complementary to one of the target RNA variants.
    • 本发明提供了检测RNA变体存在的方法,其包括进行竞争性cDNA合成的步骤,其包括对第一RNA变体特异性的第一引物,对第二RNA变体特异性的第二引物,RNA依赖性DNA 聚合酶和RNA作为模板,其中所述第一引物和所述第二引物包含等位基因特异性核苷酸部分,靶特异性序列和具有共同序列和/或鉴别序列的标签单位,使得序列 所述标签单元与所述第一或第二RNA变体不互补,其中从所述竞争性cDNA合成获得的每种cDNA产物由仅与一种靶RNA变体互补的序列延伸的一个引物的序列组成。
