    Abstract: The present invention is directed to novel methods for in vitro and in vivo detection of target nucleic acid molecules, including DNA and RNA targets, as well as nucleic acid analogues. The present invention is based on protein complementation, in which two individual polypeptides are inactive. When the two inactive polypeptide fragment are brought in close proximity during hybridization to a target nucleic acid, they re-associate into an active, detectable protein.

    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: The present invention is directed to a method for detecting and quantifying rare mutations in a nucleic acid sample. The nucleic acid molecules under investigation can be either DNA or RNA. The rare mutation can be any type of functional or non-functional nucleic acid change or mutation, such as deletion, insertion, translocation, inversion, one or more base substitution or polymorphism. Therefore, the methods of the present invention are useful in detection of rare mutations in, for example, diagnostic, prognostic and follow-up applications, when the targets are rare known nucleic acid variants mixed in with the wildtype or the more common nucleic acid variant(s).

    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.
