    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 relates to supramolecular bioconjugates and to methods for assembling and utilizing supramolecular bioconjugates. Supramolecular bioconjugates comprise a plurality of first nucleic acids and a plurality of mediators wherein each mediator comprises a second nucleic acid complementary to a sequence within said plurality of first nucleic acids. To assemble a supramolecular bioconjugate, one or more sets of bioreactive agents are coupled to the plurality of mediators, forming a plurality of bioreactive complexes. The plurality of bioreactive complexes are hybridized to the plurality of first nucleic acids to form the supramolecular bioconjugate. Bioconjugates can be used to detect and isolate targets, to screen samples for targets such as antigens, to treat patients with multiple agents or to diagnose disorders in the form of a kit.

    Abstract: Chromosomal abnormalities are responsible for a significant number of birth defects, including mental retardation. The present invention is related to methods for non-invasive and rapid, prenatal diagnosis of chromosomal abnormalities based on analysis of a maternal blood sample. The invention exploits the differences in DNA between the mother and fetus, for instance differences in their methylation states, as a means to enrich for fetal DNA in maternal plasma sample. The methods described herein can be used to detect chromosomal DNA deletions and duplications. In a preferred embodiment, the methods are used to diagnose chromosomal aneuploidy and related disorders, such as Down's and Turner's Syndrome.

    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. Numerous exemplary target test sequences (SEQ ID NO:1 to SEQ ID NO:600) are set forth. The assay of the present invention is also useful to characterize the preferred binding sequences of any selected DNA-binding molecule.

    Abstract: The present invention defines an assay useful for screening libraries of synthetic or biological compounds for their ability to bind specific DNA test sequences. The assay is also useful for determining the sequence specificity and relative DNA-binding affinity of DNA-binding molecules for any particular DNA sequence. Also described herein are potential applications of the assay, including: 1) the detection of lead compounds or new drugs via the mass screening of libraries of synthetic or biological compounds (i.e., fermentation broths); 2) the design of sequence-specific DNA-binding drugs comprised of homo- or hetero-meric subunits of molecules for which the sequence specificity was determined using the assay; and 3) the use of molecules for which sequence specificity was determined using the assay as covalently attached moieties to aid in the binding of nucleic acid or other macromolecular polymers to nucleic acid sequences.
