Abstract:
1. A primer for amplifying a target nucleic acid sequence, wherein the primer is a labeled nucleic acid including at least one of structures represented by the following formulae (16), (16b), (17) and (17b) and exhibits an exciton effect: where in the formulae (16), (16b), (17) and (17b), B is an atomic group having a natural nucleobase (adenine, guanine, cytosine, thymine, or uracil) skeleton or an artificial nucleobase skeleton, E is: (i) an atomic group having a deoxyribose skeleton, a ribose skeleton, or a structure derived from either one of them, or (ii) an atomic group having a peptide structure or a peptoid structure, Z L D is CR, N, P, P═O, B, or SiR, and R is a hydrogen atom, an alkyl group, or an arbitrary substituent, b is a single bond, a double bond, or a triple bond, or in the formulae (16) and (16b), L where in the formulae (16) and (17), E is the atomic group described in item (i), and at least one O atom in a phosphoric acid linkage may be substituted with an S atom, in the formulae (16b) and (17b), E is the atomic group described in item (ii), and in the formulae (17) and (17b), the respective Bs may be identical to or different from each other, and the respective Es may be identical to or different from each other.
