Oligonucleotides for detection test of polymorphism of EGFR exon 19 and use therof

摘要

An oligonucleotide for a detection test of a polymorphism of EGFR exon 19, the oligonucleotide being at least one selected from the group consisting of a P1 oligonucleotide and a P1′ oligonucleotide, the P1 oligonucleotide having a 3′ end subjected to an extension inhibition treatment, which has an identity of at least 80% with respect to a base sequence including at least the 115th to the 123rd bases of the base sequence indicated in SEQ ID NO: 1 and has a length of from 9 to 80 bases; and the P1′ oligonucleotide having a 3′ end subjected to an extension inhibition treatment, which hybridizes under stringent conditions with a complementary strand of a base sequence including at least the 115th to the 123rd bases of the base sequence indicated in SEQ ID NO: 1 and having a length of from 9 to 80 bases.
