摘要
A method is provided which enables quick, convenient, inexpensive, and high sensitivity confirmation of nucleic acid amplification after a nucleic acid amplification reaction. The DNA fragment in accordance with the present invention is a single-stranded DNA fragment containing a hairpin structure which in turn contains a bulge, wherein the DNA fragment is used as being attached to the 5' end of a primer used in nucleic acid amplification. The nucleic acid amplification confirmation method in accordance with the present invention quantifies a hairpin primer containing the DNA fragment at its 5' end by using bulge-binding fluorescent molecules after carrying out PCR or like nucleic acid amplification reaction using the hairpin primer. SNPs are detected quickly and conveniently at low cost and with high sensitivity by applying the nucleic acid amplification confirmation method, for example, to allele specific PCR.
