An object of the present invention is to provide a method for accurately and quantitatively discriminating and detecting a wide variety of gene mutations, or particularly, single base substitutions or point mutations. In an ASP for analyzing gene mutations, or particularly, single base substitutions or point mutations, when a non-nucleotide component is added to the 5′ end of at least one of the ASP and a primer paired therewith before amplification by PCR and amplification products thereof are separated by ion-exchange chromatography, even the amplification products having the same length can be separated and detected.
本发明的目的是提供一种方法,用于准确和定量地鉴别和检测各种
基因突变,特别是单碱基替换或点突变。在用于分析
基因突变,特别是单碱基置换或点突变的 A
SP 中,当在 PCR 扩增前在至少一种 A
SP 的 5′端和与之配对的引物中加入非核苷酸成分,并用离子交换色谱法分离其扩增产物时,即使具有相同长度的扩增产物也能被分离和检测出来。
