The present invention provides a novel molecule that can be used for detection of sIgA. The sIgA-binding nucleic acid molecule of the present invention is characterized in that it binds to secretory immunoglobulin A (sIgA) with a dissociation constant of 37.7 nM or less, and preferably includes a polynucleotide consisting of any of base sequences of SEQ ID NOs: 1 to 12 or a partial sequence thereof, for example. According to the sIgA-binding nucleic acid molecule of the present invention, it is possible to detect sIgA in saliva.
本发明提供了一种可用于检测 sIgA 的新型分子。本发明的 sIgA 结合型核酸分子的特征在于,它与分泌型免疫球蛋白 A(sIgA)的结合解离常数为 37.7 nM 或更低,并且优选包括由 SEQ ID NOs: 1 至 12 的任何碱基序列或其部分序列组成的多核苷酸。根据本发明的 sIgA 结合型核酸分子,可以检测唾液中的 sIgA。
