Abstract: Methods are described for separation and analysis, and a kit for separation and analysis, of single nucleotide polymorphisms, or mutations, in target nucleic acid using denaturing gradient electrophoresis through supporting media containing one or more immobilized nucleic acid capture ligand. The method is especially useful for analyzing genetic haplotypes in samples with multiple linked polymorphic sites.

Abstract: A method has been developed which utilizes functionalized optical fibers as a solid support for the assembly of combinatorial libraries of compounds. The optical fibers are used to direct light, heat or a combination thereof to the compounds tethered to the fibers surface. Utilizing the method of the instant invention reactions occurring by both photochemically and thermally allowed pathways are accessible. In a preferred embodiment of the invention, the optical fibers are used to screen the array by fluorescence spectroscopy of labeled target molecules which bind to the immobilized library compounds.

Abstract: This invention features methods, apparatus and kits for performing nucleic acid hybridization and amplification reactions on a support. Such methods and apparatus are useful in diagnostic and therapeutic processes for synthesizing nucleic acid and detecting target nucleic acids in a sample.
