    摘要: Apparatus and methods for carrying out biochemical processes directly on a substrate are provided. A substrate assembly includes a cartridge that removably supports a substrate in a fixed position, and a reaction containment member that is removably located on top of the substrate. The reaction containment member includes one or more cavities that form chambers directly above one or more target locations on the surface of the substrate. The chambers can be used to conduct biochemical processes directly over the substrate, as well as to perform thermal cycling of material contained inside the chamber using a heating element disposed directly on the substrate. The substrate assembly is preferably used in combination with a processing machine that dispenses materials into the chambers and that conducts biochemical reactions of materials contained within the chambers, without requiring the substrate assembly to be moved from one location to another location during the processes.

    摘要: In one aspect, described are methods of sequencing of polynucleotides using a sequential step procedure. The methods of the invention begin with the provision of a single-stranded polynucleotide template that is annealed with a primer, forming a template-primer complex. The methods of the invention can provide for adding discrete nucleotides by a polymerase to the template-primer complex, where the added nucleotides can be labeled. The methods of the invention can involve the identification of a polynucleotide or polynucleotides having a contiguous non-redundant string or a superimposed non-redundant string pattern. The detection of the presence of a non-redundant contiguous string can be used, for example, to identify a particular gene. Alternatively, for example, if the non-redundant contiguous string is not unique to a particular gene, the string can be used to form a DNA library that can then be searched, for example, with a second string. Similarly, a superimposed non-redundant string pattern can be used, for example, to identify a gene or to search a DNA library. Such strings can be used, for example, in annealing reactions and in computer searches of a database having a catalog of sequenced polynucleotides.
