摘要： Embodiments of the invention relate to a branched or multichain nucleic acid switch adapted to switch from a first conformation to a second conformation upon ligand binding. The switch includes a probe strand, P, which includes the ligand binding domain; a switching framework which includes a cover strand (C), and a tether that holds P and C together and a signaling apparatus. Some embodiments include a toggle strand (T) where now the tether holds P, C, T, and the signaling apparatus together. As the switch changes between the first and second conformations; the signaling apparatus reports the state of the switch. The signaling entity is typically a lumiphore and a quencher located along the switching framework. Nucleic acid switches have applications in real time assays for diverse agents including infectious agents, environmental toxins, and terrorist agents, as well as screening' methods for such agents. Further applications are found for nanoelectronics, nanofabrication and nanomachines.
摘要翻译：本发明的实施方案涉及适合于在配体结合后从第一构象切换至第二构象的分枝或多核酸核酸开关。该开关包括探针链P，其包含配体结合结构域; 包括盖股（C）和将P和C保持在一起的系绳和信号装置的开关框架。一些实施例包括肘节线束（T），其中绳索现在将P，C，T和信号装置保持在一起。随着开关在第一种和第二种构象之间变化，信令装置报告交换机的状态。信令实体通常是沿交换框架定位的发光体和猝灭剂。核酸开关可用于实时分析各种物质，包括传染物，环境毒素和恐怖分子，以及筛选这些物质的方法。纳米电子学，纳米加工和纳米机器还有其他应用。

摘要： A method is disclosed to obtain oligonucleotide sequences with high affinity to target molecules. By design, the oligonucleotides have a defined primary and secondary structure. The affinity for binding to target species is classified or quantified by assay measurements using physical measurements rather than being based primarily on separations. Targets include but are not limited to proteins, polymers, biological membranes including cells and organelles and small molecules.

摘要： In one embodiment, the present invention relates to fluorescent nucleic acid constructs and methods of using these switchable constructs to rapidly screen for target molecule interactions. More particularly, an RNA/DNA chimera comprising a fluorophore-quencher pair and a nucleic acid construct is disclosed for the rapid screening of interactions between the HIV-1 nucleocapsid protein, NCp7, and a stem-loop region, SL3, of the HIV-1 RNA, or antagonists thereof. The compositions and methods disclosed herein can be used in preferred aspects of the present invention for diagnosing disease states, distinguishing the presence of infectious or toxic agents, drug discovery and design, and molecular electronic applications.
