    Abstract: This invention relates to methods for detecting and sequencing of target double-stranded nucleic acid sequences, to nucleic acid probes and arrays of probes useful in these methods, and to kits and systems which contain these probes. Useful methods involve hybridizing the nucleic acids or nucleic acids which represent complementary or homologous sequences of the target to an array of nucleic acid probes. These probe comprise a single-stranded portion, an optional double-stranded portion and a variable sequence within the single-stranded portion. The molecular weights of the hybridized nucleic acids of the set can be determined by mass spectroscopy, and the sequence of the target determined from the molecular weights of the fragments. Nucleic acids whose sequences can be determined include nucleic acids in biological samples such as patient biopsies and environmental samples. Probes may be fixed to a solid support such as a hybridization chip to facilitate automated determination of molecular weights and identification of the target sequence.

    Abstract: The invention relates to bis-protein-DNA conjugates. A protein having a specific ligand binding activity is covalently linked to each end of a derivatized DNA molecule. These bis-protein-DNA conjugates can be used for immunoassays, PCR assays and measuring distances between proteins at up to 3.4 A resolution. The invention also relates to methods of synthesizing these bis-protein-DNA conjugates. Synthesis of the conjugates entails derivatizing the 5' or 3' end of a DNA oligonucleotide and covalently linking that DNA to a protein. The DNA can be conjugated to the proteins, including antibodies or Fab' fragments, using disulfide bond linkage.

    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.
