An aptamer capable of binding to a histidine peptide is provided. A nucleic acid used as the aptamer capable of binding to a histidine peptide is any of the following nucleic acids (a) to (d): (a) a nucleic acid having a base sequence represented by SEQ ID NO: 17: GGUN n AYU m GGH (SEQ ID NO: 17), where in the nucleic acid (a), N represents A, G, C, U, or T, n of Nn represents the number of Ns and is an integer from 1 to 3, Y represents U, T, or C, m of Um represents the number of Us and is an integer from 1 to 3, and H represents U, T, C, or A; (b) a nucleic acid having a base sequence obtained by substitution, deletion, addiction, or insertion of one or more bases in a base sequence of the nucleic acid (a) and being capable of binding to the histidine peptide; (c) a nucleic acid having a base sequence represented by SEQ ID NO: 18: GGCGCCUUCGUGGAAUGUC (SEQ ID NO: 18); and (d) a nucleic acid having a base sequence obtained by substitution, deletion, addition, or insertion of one or more bases in a base sequence of the nucleic acid (c) and being capable of binding to the histidine peptide. |
