Disclosed is a nucleic acid hybridization assay composition for detecting the presence or absence of a target oligo- or polynucleotide in a sample. The composition comprises: a solid matrix having at least one surface which is substituted with a first intercalator capable of binding dsDNA, dsRNA, or DNA-RNA hybrids; a second intercalator, which may or may not comprise at least one fluorophore, said intercalator or said fluorophore, each acting as either an energy donor or an energy acceptor: and an oligo- or polynucleotide probe which is specifically hybridizable with the target oligo- or polynucleotide and has directly or indirectly bound thereto, at least one lanthanide metal chelate or at least one fluorophore, each acting as either an energy donor or an energy acceptor. Also disclosed are a method and kit for its use.
本发明公开了一种核酸杂交检测组合物,用于检测样品中目标寡核苷酸或多核苷酸的存在或缺失。该组合物包括:具有至少一表面被第一插入剂取代的固体基质,该第一插入剂能够结合dsDNA,dsRNA或DNA-RNA杂交物;第二插入剂,可以包含至少一个荧光团,该插入剂或该荧光团各自作为能量给体或能量受体:以及一种寡核苷酸或多核苷酸探针,该探针能够与目标寡核苷酸或多核苷酸特异性杂交,并且直接或间接地结合至少一种镧系金属螯合物或至少一种荧光团,该荧光团或螯合物各自作为能量给体或能量受体。本发明还公开了其使用的方法和试剂盒。
