    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: DNA which encodes the polypeptide streptavidin has been isolated as a fragment 2 kb in length derived from a restriction endonuclease digestion of the chromosomal DNA of Streptomyces avidinii. The nucleic acid sequence of the gene and the amino acid sequence of the polypeptide have been determined. A fused gene has been prepared which comprises the streptavidin gene fused to a gene encoding the human LDL receptor. Expression of the gene fusion results in a fused streptavidin-human LDL receptor polypeptide. Methods are provided for using the fused gene to produce labeled, chemically modified proteins in vivo and to isolate a protein knowing only the nucleotide sequence of the gene encoding the protein.

    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.
