    摘要: This invention provides fluoroassay which comprises labeling analyte molecules with a fluorescent material having a nucleic acid portion stained with a sufficient number of fluorochrome molecules so as to be measurable as fluorescent spots, and a reactive group binding to the analyte molecule specifically, immobilizing the labeled analyte on a solid phase, and counting the number of fluorescent spots. The nucleic acid portion of the fluorescent labeling material is a double-stranded or single-stranded nucleic acid, and the staining with the fluorochrome molecules is performed with intercalating type, minor groove binding type, or covalently binding to the nucleic acid type.

    摘要: The photocleavable cyclic oligonucleotide according to the invention is the one that possesses a base sequence having the hybridization ability toward DNA or RNA to targeted, and is further provided with the structure cyclized by a photocleavable group. Accordingly, the photocleavable cyclic oligonucleotide according to the invention, after having been introduced in vivo, is hardly susceptible to the nuclease decomposition reaction owing to its cyclic structure and thus it is capable of diffusing toward the predetermined sites in vivo with sufficient time. Moreover, by being irradiated with the light at an appropriate wavelength after a predetermined period of time, the photocleavable group as described above is cleaved photochemically, thus cutting the predetermined bond. This permits the oligonucleotide that was cyclic to be a linear oligonucleotide which expresses the function of an antisense oligonucleotide.
