Abstract: Methods and compounds, including compositions therefrom, are provided for determining the sequence of nucleic acid molecules. The methods permit the determination of multiple nucleic acid sequences simultaneously. The compounds are used as tags to generate tagged nucleic acid fragments which are complementary to a selected target nucleic acid molecule. Each tag is correlative with a particular nucleotide and, in a preferred embodiment, is detectable by mass spectrometry. Following separation of the tagged fragments by sequential length, the tags are cleaved from the tagged fragments. In a preferred embodiment, the tags are detected by mass spectrometry and the sequence of the nucleic acid molecule is determined therefrom. The individual steps of the methods can be used in automated format, e.g., by the incorporation into systems.

Abstract: The identity of a nucleotide of interest in a target nucleic acid molecule is determined by combining the target with two primers, where the first primer hybridizes to and extends from a location 3′ of the nucleotide of interest in the target, so as to incorporate the complement of the nucleotide of interest in a first extension product. The second primer then hybridizes to and extends based on the first extension product, at a location 3′ of the complement of the nucleotide of interest, so as to incorporate the nucleotide of interest in a second extension product. The first primer then hybridizes to and extends from a location 3′ of the nucleotide of interest in the second extension product, so as to form, in combination with the second extension product, a nucleic acid fragment. The first and second primers are designed to incorporate a portion of the recognition sequence of a restriction endonuclease that recognizes a partially variable interrupted base sequence. i.e.

Abstract: Cationic polyelectrolyte comprising multiple quaternary ammonium residues, e.g., poly(diallyldimethylammonium)chloride (PDADMAC) may be used in analytical and separation techniques involving polynucleotides. This polymer and polynucleotides form a strong interaction that may be utilized in separation techniques for polynucleotides, and for stabilizing polynucleotides on a surface.

Abstract: The identity of a nucleotide of interest in a target nucleic acid molecule is determined by combining the target with two primers. The first primer is immobilized to a substrate and hybridizes to and extends from a location 3′ of the nucleotide of interest in the target, so as to incorporate the complement of the nucleotide of interest in a first extension product. The second primer then hybridizes to and extends based on the first extension product, which is immobilized to the substrate via the first primer, at a location 3′ of the complement of the nucleotide of interest, so as to incorporate the nucleotide of interest in a second extension product. The second extension product then dissociates from the first extension product and thus from the substrate and re-hybridizes to another first primer molecule that has not extended.

Abstract: A novel class or family of TGF-&bgr; binding proteins is disclosed. Also disclosed are assays for selecting molecules for increasing bone mineralization and methods for utilizing such molecules. In particular, compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member, particularly a bone morphogenic protein. Increasing bone mineral density has uses in diseases and conditions in which low bone mineral density typifies the condition, such as osteopenia, osteoporosis, and bone fractures.
