| 摘要 |
Disclosed is a method for detecting mutation(s) in nucleotide sequence, which comprises performing a nucleic acid amplification reaction by using an oligonucleotide or a salt thereof as a primer and a nucleic acid in a sample as a template and detecting a reaction product, wherein the oligonucleotide is so modified at the nucleotide at the second position from the 3'-terminus as to inhibit the nucleic acid synthesis. Also disclosed is a kit for the method. According to the present invention, since it is possible to completely eliminate any false positive result in the determination and correspond to various mutation patterns by a single run of PCR1 reaction, it becomes possible to design a drug-resistance determination system, which can detect possible plural genetic mutations by a single run of multiplex PCR.
