    摘要: The present invention includes a method and device for performing automated SELEX. The steps of the SELEX process are performed at one or more work stations on a work surface by a robotic manipulator controlled by a computer. The invention also includes methods and reagents to obviate the need for size-fractionation of amplified candidate nucleic acids before beginning the next round of the SELEX process.

    摘要: Described herein are methods for identifying and preparing bivalent binding molecules to 7 transmembrane G protein-coupled receptors. The methods disclosed herein are based on the SELEX method for generating high affinity nucleic acid ligands. SELEX is an acronym for Systematic Evolution of Ligands by EXponential enrichment. The methods of this invention combine two or more binding domains to two or more different epitopes of the same 7 transmembrane G protein-coupled receptor. These bivalent binding molecules are useful as therapeutic and diagnostic agents.

    摘要: A Nucleic acid ligand “Biochip” is disclosed, consisting of a solid support to which one or more specific Nucleic acid ligands is attached in a spatially defined manner. Each Nucleic acid ligand binds specifically and avidly to a particular Target molecule contained within a Test mixture, such as a Bodily fluid. The Target molecules include, but are not limited to, proteins (cellular, viral, bacterial, etc.) hormones, sugars, metabolic byproducts, cofactor, and intermediates, drugs, and toxins. In principle, the Biochip could be used to test any chemically complex mixture provided that Nucleic acid ligands to components suspected of being present in the mixture are attached to the Biochip. Thus, the Nucleic acid ligand Biochip will have a wider use in environmental testing, etc.

    摘要: Methods are provided for the production of nucleic acid ligands against target molecules using a procedure known as Transcription-free Systematic Evolution of Ligands by EXponential enrichment (Transcription-free SELEX). The Transcription-free SELEX method assembles nucleic acid ligands from fragments of synthetic nucleic acids by annealing those fragments to a complementary template, and then ligating the fragments together.

    摘要: A method for detecting a target molecule in a test mixture suspected of containing said target molecule is described. The nucleic acid ligand capable of binding to the target molecule has a first sequence A and a second sequence B, which are partially complementary sequences that form an imperfect intramolecular duplex, which unwinds upon the binding of the target to the nucleic acid ligand. Sequences A and B are able to participate in extramolecular hybridization reactions only when the duplex is unwound. Three different cascade nucleic acids contain a first sequence and a second sequence, which are partially complementary sequences. At least one sequence is exactly complementary to A or B. The second sequence may be complementary to A or B, or may be a third sequence C, or its complement. The test mixture suspected of containing the target molecule is contacted with the nucleic acid ligand, causing the duplex of the nucleic acid ligand to unwind such that sequences A and B become available for extramolecular hybridization. This mixture is contacted with the first, second, and third cascade nucleic acids so that the unpaired A and B sequences triggers a cascade of intermolecular hybridization involving the cascade nucleic acids in which intermolecular hybridization takes place between A and its complement, B and its complement, and between C its complement, leading to the formation of a multimolecular hybridization complex. The presence of the multimolecular hybridization complex is then detected.
