Pcr primer linked to complementary nucleotide sequence or complementary nucleotide sequence including mis-matched nucleotides and method for amplifying nucleic acid using the same

Abstract

The present invention relates to a primer for PCR obtained by, directly or through inosine as a linker, linking a complementary nucleotide sequence or a complementary nucleotide sequence including a mis-matched nucleotide sequence to the 5′-terminal of a forward or reverse primer; and to a PCR method including a step of mixing a nucleic acid template in a PCR composition including the primer and then performing PCR on the mixture. The primer for PCR of the present invention includes a complementary nucleotide sequence or a mis-matched nucleotide sequence in a complementary nucleotide sequence, which is linked to the 5′-terminal thereof directly or via a linker, thereby lowering the sensitivity increase due to the increase in amplification products and reducing non-specifically occurring reactions in PCR.
