摘要： An oligonucleotide is provided, which has at least a base sequence A, which is 10-30 nucleotides in length and homologous to a part of a specific nucleic acid sequence to be amplified, and a base sequence B, which is 10-30 nucleotides in length and complementary to a sequence 3' to the part of the specific nucleic acid sequence to be amplified. Sequences A and B are separated by a spacer region of 0-20 nucleotides. The oligonucleotide is used in an amplification method, wherein the oligonucleotide is mixed with a sample containing a specific nucleic acid sequence to be amplified and allowed to anneal to the specific nucleic acid sequence in the sample. The annealed oligonucleotide acts as a primer in an elongation reaction, whereas any nonannealed oligonucleotide is decomposed, except for at least part of the base sequence A. The elongation product is then denatured to a single strand for use as a template to which the remaining oligonucleotide anneals to form a primer for subsequent elongation. Also provided is a detection method, which allows for detection of a specific nucleic acid sequence in a sample, as well as reagent kits for use in the amplification and detection methods.
