摘要： The present invention relates to compositions and methods for the detection and characterization of nucleic acid sequences and variations in nucleic acid sequences. The present invention relates to methods for forming a nucleic acid cleavage structure on a solid support and cleaving the nucleic acid cleavage structure in a site-specific manner. For example, in some embodiments, a 5′ nuclease activity from any of a variety of enzymes is used to cleave the target-dependent cleavage structure, thereby indicating the presence of specific nucleic acid sequences or specific variations thereof.

摘要： A horizontal electrophoresis assembly is described which is designed to utilize very thin gels of polyacrylamide. The assembly allows for water cooling of the gel during electrophoresis so that higher voltages can be applied to the gel without polymer degradation. The gel mold is made from a set of glass plates which are clamped into place defining a gel mold between them. In one embodiment, the site of field introduction is separated from the site of sample introduction so that the electric field is generally linear at the region of sample introduction.

摘要： An apparatus is disclosed to optically determine which of four fluorophores is attached to a band of DNA molecules on an electrophoresis gel. The apparatus includes four separate band pass interference filters and four wedge prisms to create four discrete areas of light on a detector. Digital comparison of the relative intensity of light sensed in the four discrete areas determines the identity of the excited fluorophore.
