Abstract: The invention is directed to constructs and compositions containing multimeric forms of nucleic acid. Multimeric nucleic acids comprise single-stranded nucleic acids attached via biotin to streptavidin and bound with a functional group. These constructs can be utilized in vivo to treat or identify diseased tissue or cells. Repeated administrations of multimeric nucleic acid compositions produce a rapid and specific amplification of nucleic acid constructs and their attached functional groups. For treatment purposes, functional groups may be toxins, radioisotopes, genes or enzymes. Diagnostically, labeled multimeric constructs may be used to identify specific targets in vivo or in vitro. Multimeric nucleic acids may also be used in nanotechnology and to create self-assembling polymeric aggregates such as membranes of defined porosity, microcircuits and many other products.

Abstract: The invention provides a method for purifying or isolating double stranded DNA intact using triple helix formation. The method includes the steps of complexing an oligonucleotide and double stranded DNA to generate a triple helix and immobilization of the triple helix on a solid phase by means of a molecular recognition system such as avidin/biotin. The purified DNA is then recovered intact by treating the solid phase with a reagent that breaks the bonds between the oligonucleotide and the intact double stranded DNA while not affecting the Watson-Crick base pairs of the double helix. The present invention also provides a method for purifying or isolating double stranded DNA intact by complexing the double stranded DNA with a specific binding partner and recovering the complex during electrophoresis by immobilizing it on a solid phase trap imbedded in an electrophoretic gel.

Abstract: The present invention defines a DNA:protein-binding assay useful for screening libraries of synthetic or biological compounds for their ability to bind DNA test sequences. The assay is versatile in that any number of test sequences can be tested by placing the test sequence adjacent to a defined protein binding screening sequence. Binding of molecules to these test sequence changes the binding characteristics of the protein molecule to its cognate binding sequence. When such a molecule binds the test sequence the equilibrium of the DNA:protein complexes is disturbed, generating changes in the concentration of free DNA probe. Also described herein is a method to capture DNA that has been released from the DNA:protein complex.

Abstract: The present invention relates to a method for measuring the amount of a target nucleic acid in a sample using a standard which is designed to have one base difference compared with the gene of interest or a “target nucleic acid sequence.” Use of such standard in combination with a method of “enhancing” the difference in the standard and the test nucleic acid sample using, for example, a base extension reaction carried right at the mutation site allowing amplification of the standard and target nucleic acids with the same efficiency and facilitating quantification of the target nucleic acid. Thereafter a means of quantifying the “enhanced” standard and target nucleic acid samples is used to determine the amount of the target nucleic acid. In the preferred embodiment, the quantification means is Mass Spectrometry.

Abstract: The invention provides a method for detecting and quantifying the amount of target molecules, such as nucleic acids or proteins in a sample. The target molecules are first recognized and bounded by target-specific probes, generally nucleic acids or proteins that bind specifically to the targets, each of which is labeled with a short single-stranded nucleic acid probe, either DNA or RNA, with distinct molecular weight. This label is called an oligonucleotide mass tag. One or several standard oligonucleotide sequences can be designed with similar sequence but distinct molecular weight to those oligonucleotide mass tags. Then the oligonucleotide mass tags associated with bounded probes and the standard sequences are co-amplified using a pair of common primers. The presence and/or amount of each oligonucleotide mass tag, which corresponds to the amount of corresponding target molecule, is determined by a primer extension reaction and quantification of the primer extension product.

Abstract: The present invention provides a method for determining nucleic acid sequences of a template nucleic acid that requires no prior knowledge of the nucleic acid sequence present in the template nucleic acid. The method is based on combining information about the mass of a fragment, the mass of any one nucleotide and the combinations thereof, and the sequence specificity of a nucleotide cutter, either enzymatic or chemical cutter, to determine a sequence of a nucleic acid fragment. This method allows for de novo detection of sequences in a target nucleic acid without requiring any prior sequence information. This method is called Partial Sequencing by Fragmentation (PSBF) and it works by fragmenting a target into oligo- or polynucleotides whose masses or lengths are uniquely associated with known sequences. The identities of these sequences are determined solely by the specific fragmentation method used, and are always independent of the target. PSBF can be implemented using electrophoresis, mass spectrometry or any other method that can be used to distinguish the size of the cut nucleic acid sequence fragments.

Abstract translation: 本发明提供了一种确定模板核酸的核酸序列的方法，其不需要模板核酸中存在的核酸序列的先验知识。 该方法基于组合关于片段的质量，任何一个核苷酸的质量及其组合的信息以及核苷酸切割剂（酶或化学切割机）的序列特异性，以确定核酸片段的序列。 该方法允许从头检测靶核酸中的序列，而不需要任何先前的序列信息。 这种方法被称为通过片段化分段测序（PSBF），它的作用是通过将目标片段分成其质量或长度与已知序列唯一相关的寡核苷酸或多核苷酸。 这些序列的身份完全由所使用的具体碎片方法确定，并且始终与目标无关。 PSBF可以使用电泳，质谱法或可用于区分切割的核酸序列片段的大小的任何其它方法来实现。
